While many National Parks share a fair amount of overlap in terms of their features and offerings, Great Sand Dunes National Park offers two elements rare in most others: towering sand dunes and a whole lot of dog-friendliness. Outside of being able to explore the tallest sand dunes in North America, dogs and their owners can explore the forests, lakes and even grasslands that surround the park, many of which have their own activities. Of course, you'll have to watch out in summer since sand temperatures can reach 150 degrees mid-day, but otherwise, you'll have little to worry about besides having fun in this beautiful and unique natural setting.
Great Sand Dunes National Park is an absolute mecca for outdoor explorers and their dogs. With a wide array of different ecological systems spread throughout the park, tons of activities and just as much space to roam, plus the freedom to do so (even with your canine companion), this park is easily one of the best and most dog-friendly parks in the country.
