If playing in a giant sandbox appeals to you, the Great Sand Dunes National Park and Preserve near Alamosa is a must-visit. This giant dune field of 30sqmi (78sqkm) features at least one dune that’s more than 750ft (229m) high. Sledding down the dunes is a popular pastime, as is hiking and camping. There are also horseback riding trails and the scenic four-wheel drive on Medano Pass.
Visitors can stroke sea stars and horseshoe crabs in the sea life touch zone, hold Rosie the tarantula, stroll on the outdoor nature trail, and watch bees while learning how vital they are to the future of the planet. The Butterfly Pavilion and Insect Center have educational programs for all ages, from young children to seniors, and a gift shop filled with interesting items.
