Botswana without a doubt! I was once taking a safari in a tiny dugout mokoro canoe in the Okanvango Delta and snapped this shot - it has not been photoshopped or instagrammed it was that gorgeous

Easy answer - Pokhara Nepal! After a sleepless night we got up about 4 am and drove to the base of Sarangkot We then hiked about 1 hour up the mountain and enjoyed the best sunrise ever - yah ever! Excited about heading back to Kathmandu this Sept

Isla Amantaní in the middle of Lake Titicaca, Peru.

It was one of those rare travel moments that transcends centuries and cultures, standing at the top of the island with new friends from Spain and Germany, worshiping the falling sun at the ancient temple of a pre-Incan culture.  Not only were the views gorgeous, but the setting evoked a feeling of being in touch with an ancient people who were intimately in touch with the natural world.  Truly breathtaking, and definitely the most unique experience I had while solo backpacking South America.  Highly recommended if you're traveling through Puno and have two days and a night to experience this place.

Seattle has been darn good for sunsets since I moved here almost a year ago. Here are two of my favorite snaps!

I took this one from the shores of Elliott Bay Trail late in 2013.And then this one just a few weeks ago from CenturyLink Field as I watched a Sounders game! Don't you want to move here yet??

Saskatchewan  We refer to our province as "The Land of Living Skies" and it is definitely that.  Our sunsets are magnificent, on any day when there is no cloud cover, which is almost every day!  I've seen wonderful sunsets in other North American places, and in the tropics, but none can exceed in beauty the ones I see at home. 

Sunsets are one of my favorite things to see when I travel.  They can be so different from any other one you have seen before, it all just depends on the place.  The best on for me was in the very south of Bali.  I spent all day at the beach and the sunset made the perfect end to a great day, here is a photo I took of it.P.S Debbie where was the sunset you just saw?

Definitely Paris on my first ever evening there! I'd landed in the pouring rain, but the clouds started to clear for sunset. This was taken along by Hôtel de Ville. Bit of a rubbish photo, but I love it - it always reminds of seeing Paris for the first time!  

Kalymnos, Dodecanese Islands, Greece.

One of the really best sunsets! I do not have many pictures now but the whole package (sunsets,places to see, things to do, tranquility and everything else)is just unbeatable! Try and see, you WILL come again and again! :)

I saw one of the most beautiful sunsets in Old Bagan in Myanmar. We climbed up the Shwesandaw pagoda 1 hour before sunset. Overlooking Bagan and its temples while the light turns from a warm yellow to a dark red is truly amazing.

I feel lucky to say it's where I call home now: Venice Beach. 

Hi Debbie!...

Here are some of the sunsets that I captured with my camera...

Salta

Casapueblo

Edinburgh

Nymphenburg Palace

Eiffel Tower

I love sunsets and sunrises ... and more if I am accompanied by a beautiful woman ... hahaha

:)

Old Bagan, by the river,

that sunset i saw reminds me of a crown

Hanalei Bay Kauai, Hawaii - where we've been blessed to live. 

One of the most amazing sunsets I have ever seen was in Oia , Santorini, Greece. However a bit more wonderful even is the sunrise.

Another amazing sunset I saw in Angkor Wat, Cambodia. You have to be in the right spot where not so many people go.

The sunset on a beach at Boracay Island was rather unexpectedly amazing.

Of the ones I've seen, Lake Namtso's (in Nam Co, Tibet) is the best. Here's a picture that doesn't do it justice, taken with my crappy Canon Elph back in 2006.

like the song says... a Waterloo Sunset: it is beautiful London

I am lucky to live in Mornington Peninsula and we look west over Port Philip Bay here are a few of my Sunset Pictures from this winter. I think we should all plan to take a sunset picture on a particular day i.e 11/11/14 Starting from the date line and creating a record of the sunset on that day as the sunsets around the world creating thousands of pictures in thousands of points on our planet. Come on lets make a record of that day. Please pass it on.

My best sunsets were in Key West and Sedona.

Now with Sedona the pictures turned out absolutely spectacular we got to the highest point at where we were staying Sky Ranch Lodgeand you had the view of the red rocks in the backgrounds and it was just so gorgeous! Sky Ranch Lodge also had a separate viewing area that was more private just for guests to watch the sunset. 

Here some of my best sunsets. 

40Seconds in BerlinPoint Bonita Lighthouse

Golden Gate Bridge

Key West

Coyote Point Marina

Dana Point

Los Angeles International Airport

Imperial Beach

London

Trippy has to work on the photo uploader. I had to upload pretty much every photo 2-3 times because of unexpected error. But this one only appeared after i uploded the photo and tried to insert it here. A lot of waiting with my slow connection at the hotel.

I think every Sunset is unique and the best part is they are never repeated even at the same place so saying one sunset is better than other will not be correct. As for me the I just loved the Sunsets in Kerala Fort KochiHere is my blog post about the same:  Sunset in Fort Kochi in Kerala, a state in South India, also rightly known as God's Own Country

When cruising east of Flores Island, Indonesia anchored in front of this active puffing volcano on Kumba Island when on the sailing yacht Silolona.

Oia in Santorini island, Greece. Pricey location, but worth it!

Outside of Menemsha I would have to say the best would be at Kalalau Beach.  The cliffs of Kalalau change colors as the sun sets and its really amazing.  

Here in Amsterdam we have a lot of water, an effect of that is we have a lot rain and clouds. Next to that, the sunsets are long (because of the location on the northern hemisphere). In this equation the color changes are beautiful, and they are rare. Notice the changes in the spectacle. Here' are some pictures of the start to end of the sunset, from the view of the restaurant REM Eiland. And please mind me saying I did not use a filter. 

Sorry for the lamps in the picture, I forgot to step outside.

Santorini

Hi,

I can send you only two different PhonsavanSunset on jars site n°1

Sunset on the jungle near Phonsavan

Sunsets on the Isles of Scilly are some of the best I have seen anywhere.

This was taken outside of Bamenda, near the grounds of the Mbingo Baptist Hospital in Cameroon, June 2012.  We were staying on top of a mountain and were eating down in the village (3/4 of a mile straight down the mountain from our house) when we saw the color start filling the sky. We dropped everything we were doing, and sprinted up to the house so we could see the sun set over the valley. Aaaaaand it was absolutely breath-taking.

Pupukea,  Sedona, Flagstaff, or  Florence

Although Phoenix, Arizona may not be the most exotic travel destination in the world, it has been a constant source of unforgettable sunsets for me. All of these photos were taken in Papago Park in Phoenix. With its dramatic landscapes and highly reflective fishing lagoons, Papago Park is the best place in Phoenix to witness a stunning sunset, especially during the winter months.

Amazing sunset photos. Here is one of mine, from earlier this summer in Duck

A great sunset has to be followed by a cool drink. Six Senses Laamu Hotel, Maldives

My best ones were in Curacao and in Bodrum

I have not seen the whole world yet, but saw some stunning sunsets in Maui(Lahaina) & St Lucia in the Caribbean.

Can't answer for the whole world but Cape Cod has amazing sunsets and a different looking sunset every night. One of my places!

Bark Bay (Apostle Islands), Cornucopia WI, USA ... Debbie, I want to share the photo's I have but I'm not sure how I can upload the photo!

#1 Langkawi Island in Malaysia 

or #2 Krabi islands in Thailand.

Mumbai wouldn't be considered among beautiful places in the world, it's a dusty humid city for the most part of the year, but a few weeks ago, I was able to capture a beautiful sunset while in the back seat of a speeding taxi.

Both of these were taken in Jamaica.

Cape Town has some of the best I have ever seen.  

Thailand especially Koh Tao

The most beautiful sunset I've ever seen and continue to see every time I go is from Carrot Bay on Tortolalooking over toward Jost van Dyke and St. Thomas.

This one in Malmo, Sweden was one of my favorites!

http://www.dtravelsround.com/2012/05/25/daily-wanderlust-sunset-malmo-sweden/

I lied above. Shortly after arriving in Korotogo, bush fire smoke gave us these.

One of my favorite places to watch the sun set is at my mom's house in Warsaw (Virginia). I must have a thousand photos of sunsets there.But my second favorite sunset was probably in Porto. The sunset seemed to last for hours, and the colors moved across the water and the bridges and the hills and the houses in a magical way.

Tough question Debbie....
Lately the best sunsets we saw were in Novalja

The sunset in the lost city Syrian Desert was pretty spectacular!

Maybe not too safe to travel there at the moment though...this was 5 years ago when I was there!

J.N. "Ding" Darling National Wildlife Refuge on Sanibel Island, Florida. From the watch tower you can see a beautiful panoramic sunset...and see a large flock of roseate spoonbills. (Was there August 2014)

I like the Town Lake Statesman Bat Observation Center in Austin TX

Honolulu HI North Shore

Wellington Harbour New Zealand

Cape Jervis coming back from Kangaroo Islandi like this question!

I don't know if it was the best, even when it's known as such, but I found the sunsets in Oia and Mikonos just wonderful. 

The sunste in the Grand Canyon is also beautiful because you see the mountains change colours from brown and greens to bright reds. 

Mykonos, Greece. 

I still think about this sunset to this day and like many of you have said, pictures cannot do it justice. 

The orange sky reflected on all of the white buildings in town, it was so unbelievably beautiful and an experience I will never forget. 

Over the Serengeti in Tanzania

Personally I would say that the view of the Freycinet Peninsula from Coles Bay in Tasmania, near Wine Glass Bay was the best I've seen.

I haven´t seen so many sunsets yet, but the one Crete was beautiful!

Bingin Beach in Bali

Great view of Blacksea from Trabzon  Turkey

Jericoacoara

Beautiful sunset, just sit on the dunes and watch the show!

This was the first sunset of my 2012 Kona vacation! Awesome sunset from the Royal Kona Resort!

I'd have to say Rio de Janeiro at Ipanema but given all the other photos I've seen in the answers, I'm having doubts about my answer now.

Kailua, Kona!

Ladies Beach in Kusadasi Turkey I think has the best sunset in the world by far.

Miami Miami Beach the sky goes on fire every sunset

Other great places to watch the sunsets around the World:

• Great Ocean Rd and Byron Bay in Australia
• Porto-Vecchio and Biarritz in France,
• Merzouga Campin Morocco
• Tanah Lot in Bali
• Sukhothai in Thailand

(Photos taken on my iPhone 5, no filter)

Swami's in SoCal.  BEAUTIFUL place to watch it go down.

The most beautiful are right out my front window  and deck on Scugog Island on Lake Scugog, Port Perry, Ontario, Canada

Cape Blanco Every night, we would walk down to the cliff, and watch the sun sink into the sea!  One evening we even witnessed the "green flash" !

South Africa. Yellows like an egg yolk, pinks like cotton candy, red and white like the ribbons on an old fashioned carousel. Can't beat it. Most beautiful sight I've ever seen.

Guernsey, Channel Islands. West coast

The sunset in the lost city of Palmyra in Syrian Desert was pretty spectacular!

Maybe not too safe to travel there at the moment though...this was 5 years ago when I was there!

Best sunset I've seen was Haleakalā 

The best sunsets in the world are in Winnipeg during the summer months. Sunsets last until 10:30 - 11:00p.m. And give the greatest bright red/orange suns you have ever seen.

The best sunsets I' ve seen were eather in the Turks and Caicos any island would do. But without over traveling the most recent best of the best sunsets were in Riviere Du Loup about 2 hours NE of Quebec City.  Just go to the dock next to the fery sit down and enjoy the show. (Sorry no photos, it was too wonderfull to stop watching.)

Vail and Arizona

South Africa. Too many gorgeous breathtaking landscapes for sunset peekaboo. Drove down the Garden Route National Park and had too many. But the best was up atop table mountain. Great friends, towards the end of the best vacation ever. Great question!

Marathon, Florida

Santorini

Guam, by far. No where else compares. Watch the sun set from Tumon Bay. I'm from California - the land of the setting sun - so it's hard for me to say it but it's true. Being out in the middle of ocean, with such dense rain clouds, you get a full spectrum of colors that can't be seen otherwise.

Balanced Rock, Arches National park, UT
Minutes before sunset everything looks like in fire. Never saw anything like that.

Oia from our balcony and a close second Conrad Maldives Rangali Island from our over water villa on our honeymoon ;)

From a photography point of view, I think that Prague has the best evening light (in the summer at least). 

Has to be Key West!!!

Prague

without any doubt

It's in the Himalaya Hills during the monsoons, when the sun is in its process to go down and it rains and you have a beautiful rainbow in front of you, you are practically sitting above the rainbow.

Tumon Bay, Guam

Gili Lankanfushi Maldives

SUNSET AT 'KHUVSGUL LAKE' OF MONGOLIA.

Kailua Kona - the vog creates amazing sunsets. 

Gili Islands!

Have seen many amazing colourful sunsets.

The most beautiful I've seen in the last 12 months was in Roda Corfu

I currently live in Ireland and love the sunsets in my town Carrick-on-Shannon. I never get tired of watching the sky here...the beautiful colors and clouds. I have being in other countries but love the ones here best.

Mallory square is the ultimate sunset if you like margaritas.  must have taken a few hundred pictures there over the years but like my salt shaker they are forever lost...

Haleakala Crater in Maui, Hawaii... Just saw this on my vacay to Maui last week. Amazing.

From the top of Mauna Kea on the big Island, Hawai'i! Almost 14,000 feet in elevation and watching it set into the clouds. Ahhh!

I have always been to to partial to the sunsets in Denver with the colors and the mountains.  

Someday I hope to see a sunset from everywhere in the world and then I can be a better judge!

boy the competition is tough, but I just watched a spectacular sunset on the top of Haleakalā Crater in Maui....

Experienced one of the most beautiful sunset's in Braga at the 
Bom Jesus do Monte

Best I've seen recently was certainly Mt Cargill just outside Dunedin, NZ. Our AirBn'B hostess casually mentioned there was a nearby spot good for sunsets so we drove up thinking we would get a nice view of the city from a hill. What we were treated to though was outstanding 270 degree panoramas on a night that just so happened to be an absolutely perfect one for a sunset. Just the right amount of clouds to let the light play and smatter the sky with orange, pink, purple, and all shades of blue as the sun made its exit. Was definitely the most unexpected of breathtaking natural beauties in a country filled with them. I only used the camera on my phone which doesn't even begin to properly capture it, but you get the picture. 

The most beautiful sunsets in the world is to be seen in little village close to Cape Towncalled Melkbosstrand. I am fortunate enough to live here and I have not seen a better sunset in 68 countries. The autumn sunsets are spectacular for the cloud formations and in the summer for the blood red sunsets. You can also see the moon set in the morning as the sun rises. The photos attached are not photoshopped or adjusted in any way.
