Great Sand Dunes National Park is an absolutely gorgeous example of Mother Nature at her finest. The views are stunning in every direction, and it is one of those places that makes you stop, look around, and just take it all in.
That being said, walking and hiking in sand is very different than what you might expect. I am from Minnesota, and our hikes are definitely not like this. The dunes are beautiful, but they are also a workout. Going up takes effort, and if you get winded easily, it is worth knowing that there really are not benches or easy places to stop and rest once you are out on the sand. Coming down is much easier than going up, and honestly, a lot more fun.
Barefoot is definitely an option depending on the temperature of the sand. I wore long socks under pants with hiking shoes and did pretty well, but regular shoes are absolutely going to end up filled with sand. There is really no way around it. The sand will find you. It is committed.
Even with the challenge of hiking through the dunes, I would recommend this trip to anyone who wants to experience pure natural beauty. It is peaceful, unique, and absolutely worth seeing in person. Whether you hike far or just spend time taking in the view, Great Sand Dunes is a place that feels special.
