Gather the book club, because we're heading where Ernest Hemingway spent his last days: beautiful Sun Valley, Idaho. This ethereally perfect mountain town is not just for the Hemingway fans. Endless outdoor activities like backcountry skiing, sledding, and even heliskiing await the more intrepid ones in the crew. For the artsy hibernator, the town is filled with gallery exhibitions. And for another celestial experience on our list, stay at the Hotel Ketchum. The boutique hotel is located on the Dark Skies Reserve, where you'll get an untarnished look at our amazing galaxy. From bibliophiles to daredevils to the starry-eyed, Sun Valley seems to have something for everyone. It's a group-pleaser!
