I'm specifically looking at Whidbey Island because I'd love to experience a little bit of Washingtonian island life. How would I go about getting there? Is it easy to get around the islands by walking or public transportation?
On the non-Whidbey front, you might consider:
Mentioned in this answer:
If you don't already have a car with you in Seattle, you're going to need to rent one for your trip to Whidbey Island. I don't usually recommend having a car while in Seattle just because parking is way more of a hassle than it's worth, but for your trip to Whidbey Island, definitely rent one for that leg of your trip. There is public transportation, but the trip is quite a trek and all the stops would cut into your exploring time greatly. Another thing to consider is that Whidbey Island is not a metropolitan area and isn't heavily populated, so you'll definitely need a car to get around. There's a bus that runs around Whidbey Island, but as you can imagine, buses in such a remote place don't run very often, so I wouldn't depend on it. Buses also don't go to too many popular sightseeing spots. I'll break down the trip there to two steps and this is pretty much the best way to go about this trip:
A few notes about the ferry:
If you're unsure of where to go on the island, I have a few suggestions:
Should you get hungry at the ferry terminals on either side:
