Super fun trail, very steep at points! I went on a cloudy day/windy day on accident, so definitely be aware of wind levels when you’re going to the Sand Dunes! ;)

So much fun! It was the perfect level of difficulty. There was one part where we crawled on all fours because it was so steep. We took our dog and he did really well. He wore boots the whole way to protect his paws. Highly recommend!

Absolutely loved this trail! We hit High Dune followed by Star Dune and it was about 7 miles long. Hiked on 12/5 and the weather was perfect. We hit some snow around Star Dune but it just made the hike more unique and memorable. Definitely give yourself more time than you think- the sand makes everything harder!

I don’t think there is really an official trail up there, but I would recommend to find the highest longest ridge to follow otherwise you may have to wither back track or bear crawl up a super steep dune (which we did) ugh! I did carry a rented board to the top and my 10yo daughter, wife, and I had a blast going down!

As others have said, there's no real "trail" here, but that just made it all the more fun! We went counter-clockwise and it definitely took us away from the crowds (most people seem to be concentrated around High Dune). The dunes were no joke to hike on! The amount of sand that came out of my boots afterwards was hilarious. We hiked the whole thing in the afternoon, but came back to do a portion again at sunset. HIGHLY recommend! It was absolutely STUNNING watching the sun set over the dunes. The light is much softer and creates gorgeous shadows on the dunes during the golden hour. My husband and I actually hiked with our telescope to the top of one of the dunes to watch the sunset and stayed there until the stars came out. Brutal hike with that telescope but so so worth it. The stars here are unlike anything I've ever seen. Be careful if you're going to night hike - it is absolutely pitch black, so be sure to have headlamps, a fully charged phone to get back to camp and your ten essentials just in case. :)

Super fun and tougher than you’d expect! This takes you away from most of the footsteps of others so even though I did in the late afternoon it felt like I had the whole thing to myself.

We made our own trial to get to High Dune. It’s pretty difficult to follow any “set trails”. The sand moved and there is not any marking. Following other’s footsteps is a good way to ensure you don’t get lost if you don’t have GPS

This was amazing! The pups loved the dunes, and you can really take them anywhere in the sand. There’s no specific “trail,” but the common paths are a bit more packed down and easier to walk on. We decided to venture off the beaten path and make our own trail toward the tallest dune, Star Dune. We didn’t make it all 750 feet, but we did go up to a dune at about 600! The dogs loved it, and you will too. Otherworldly, very unique experience. Couple things to think about - very windy with blowing sand, no coverage from the sun unless the clouds love you, and the earlier the better...we got there just after the park opened and it was filling up fast. Totally worth it though to have some more privacy among the dunes, and you’ll get better photos without all of the day’s footprints!

Beautiful weather leaving at 7a from the piñon campgrounds. Sand was still firm from rain the day before.

Just wow. First time here & got lucky with an open campsite with a perfect view & a stones throw from this trail. Didnt make it the entire way, we started late and the temp dropped quickly on us, high sandy winds are rough

Went on a windy, cloudy morning before a thunderstorm and it was a magical experience. Definitely follow the ridges where the sand is more firm. The wind was blowing the sand around, making beautiful eddies but blasting our legs. Wear pants on a windy day (easy to say when it was cloudy) and stay on the windward side of the ridges. Tips aside, one of the coolest things I’ve ever done, 100% recommend!!! The beauty was otherworldly. If you go beyond the first high dune ridge, all that you can see for miles are dunes and mountains. Update: we went again the morning after a steady rain, and the sand was solid and cool to walk on. Perfect conditions for hiking, and the patterns that showed up were breathtaking. I walked barefoot in the dunes for hours with plenty of sunscreen and plenty of water.

Beautiful hike, and though sandy, hot, and hard, it’s so worth it! We tried sliding down in a cardboard box, but it didn’t work very well for us and we ended up just tumbling down the dune. Overall, it was a wonderful trip!

Wow. Definitely worth the drive and $20 entry fee. Tough hike at times to get to the top. Gorgeous when you're there - sand dunes as far as you can see. Minus the temp, I felt like I could be in the Sahara. Did this hike at sunset as another viewer suggested, and it was stunning. Bare feet the whole way. Had my two dogs with me and I'd suggest getting booties for those bringing theirs. The paths to and from the dunes were lined with small cactus. Also, even if the sand isn't hot, I suspect running on this was pushing their paw pads apart. Both started showing signs of paw irritation and ended up putting them on - they went from 0 to 100 real quick. This was by far the most distinctive hike I've done. Very happy hiker here.

I didn't finish this hike all the way to the top of High Dune as we'd rented sand sleds from the Oasis store down the road and decided to run them on the lower slopes, but I don't regret not making it to the top. The sand gets to 140 degrees F in August and climbing up the dunes can be absolutely brutal. The views from the top sound great, but sand dune hiking can be more mentally challenging than it's worth (IMHO) and I would highly recommend sand sledding if you want a more fun experience in the dunes!

a truly amazing view from the top!

Ooops! The review below was for High Dunes Trail!

Sat May 27 2017

Amazing! Incredible! You can't comprehend how vast these Dunes are until you are actually there. Strenuous hike that took us about 2 hours round trip but well worth it, not only when you reach the top but also along the way when your in the middle of them. Definitely best to go earlier in the morning by 9:00 at the latest. This is a holiday weekend and on our way out we counted 175 cars in line to get in the park at 11:00 am!

One of my favorite places to hike. I've hiked along the dunes, Medano creek and in the forested areas to the East. The dunes were created due to high wind, so take that into consideration while packing your gear. This National Park is a gem and a must-visit location. Visit the interactive Ranger station and bring your camera for sunset shadows on the dunes.
