Family fun in Mammoth means lots of time spent outdoors, but what do you do when it rains? With kids in tow, you'll need toys, a good board game, and maybe some candy—ice cream wouldn't hurt either. Head to Mammoth Fun Shop for all of the above. Grown-ups will also find fun novelties, souvenirs, and gifts. Stop in for a coffee, milkshake, or root beer float and try out a game to play the next time you need some screen-free indoor fun.
