San Antonio, Texas
Looking for a location in Colorado I can perhaps rent a cabin for at least 3 people, possibly Airbnb places, but I've never been to Colorado. Ideally an area not too close to a big city, hoping to bring out a telescope, and do some fishing with my father.
Try Pagosa Springs and stay at Fireside Inn Cabins. They have a variety of wonderful cabins and are set within walking distance to the San Juan River for fishing. The night skies are beautiful for stargazing and for an added bonus at The Springs Resort & Spa offers 23 hot mineral pools to relax in from one of the warmest, biggest, mineral springs in the world.
