Every single kind of Devils Tower memento that you can possibly imagine, from tshirts to hats to bells. Bumperstickers and magnets and models of the mountain (small, medium and large) and of course, postcards. No stamps today, though.
For me, the winner was that they were offering a completely free wifi signal. So I sat at one of their benches, used up their wifi to find directions to my next stop, wrote my postcards and enjoyed a frosty beverage before getting back on my way.
Plenty of parking and even room for the bigger vehicles. Clean bathroom and the prices are reasonable.
While you can stay here and save the $11 or so for entering the park, it's worth the money to get right close to Devils Tower. Don't come all this way and miss the last mile. read more
