Directions from Visitor Center: About 1/4 mile past the entrance to the Visitor Center, on the right side, is the entrance to the Montville Parking Area. If you get to the entrance for the Dune Parking Area, you have gone too far. The trail takes off on the east side of the parking lot.

When you reach the end of the trail, don't stop. The view east is a bit further along. Follow the dirt road and stay to the right up the hill, maybe 1/4 mile further. You will be rewarded with a view of the valley beyond. Enjoyed the hike very much.

I didn't hike the full trail, but it is somewhat shielded from elements, has a beautiful view of the dunes, and was overall very enjoyable

Just went on this trail this morning! It was a decent hike but very anticlimactic ending. We took the nature loop on our way back down, which adds hardly any milage, and that was probably the best part of the whole trail. Coolviews of the dunes on this end.

Beautiful spring hike! It’s a long hike to the end, but the views throughout were awesome! We saw big horn sheep and a followed the creek throughout. Afterwards we hit the dunes. Made for a great day.

Great trail! Some snow coverage but good traction.

We hiked the whole trail to the end and back. It led you through forests, side of the mountain and eventually to a grassland area. We went in October and choose a sunny day in the 60's to hike. It was the perfect temp! There's a old car hidden in the woods off to the right if you came from the entrance near the sand dunes. Took about 4 and a half hours with breaks and a kiddo.

Great hike

Beautiful trail through the woods and then meadows filled with wildflowers. The trail does follow the Creek, but there are only a few easy points to drop in so the pups can drink. We saw a bear across the creek early on but he ran off and we didn't see any wildlife after that. We started the hike at 7am and got back to the TH at 10 on the dot, and then included plenty of picture stops! Didn't see anyone until we were half way back down, so early is the way to go for privacy, not to mention nice cool temps and that gorgeous golden light streaming through the trees. Perfect hike!

Beautiful trail.... well marked & well kept. You follow Mosca creek the entire way - very peaceful. The views of the sand dunes are also marvelous. The first 3/4 mile is definitely the most difficult with the elevation gain. We saw very few other hikers. Be prepared for a plethora of mosquitos (the only reason I ranked it 4 stars - I wasn't prepared) !!

Made the round trip with a group of Boy Scouts ranging in ages 11 to 14. Tough on the way in with the elevation gain...well worth it! Nothing but smiles upon completion. Troop 524 recommends it!

This trail is moderately difficult with the elevation gain at an already high altitude. It provides wonderful views of the dunes and ascends into a beautiful alpine meadow setting.

A lovely, peaceful trail with great views of the sand dunes.

I absolutely loved this trail. It was beautiful! It took me, an asthmatic from Florida, just under 2 1/2 hours to get to the end (from the Great Sand Dunes NP). Frankly, I felt like the journey was far better than the destination.

If you're starting from the dune side, it's nearly entirely uphill. It is beside a creek (Mosca Creek, of course) the entire time--you always hear it. There are many places along the trail that allow you to get water from it (the best/safest spot is close to the end). The middle part (the most beautiful) is quite rocky, but easy to hike. There are beautiful meadows towards the end where you can camp with a permit. There are two flowing creek crossings without a bridge (and one with), but they're very shallow. The one nearest to the end is quite muddy.

There are opportunities for panoramas and photos at every turn. Expect to see people on the trail as the park is quite busy this time of the year. But this hike is simply worth it!

Great trail offering a lot of variety offering wooded areas, rocky trails and meadows. Beautiful views along the way. The trail followed a creek the whole way. Completed the hike in four hours which included a stop for lunch and then stop for a foot soaking in the creek. Great hike. Would do it again.

Sweet trail in the Great Sand Dunes National Park. I combined this trail with the Montville nature loop trail to add a bit more to it. Overall easy trail with awesome, variable terrain and great views.

My daughter and had a great day hiking this trail. It was the first time on this trail for us. It is well defined and beautiful from start to finish going from rocky hillside to wooded areas to open meadows,etc. My one recommendation is bring LOTS of bug spray. The mosquitos are intense!!

A great hike. The hike is closer to 8 miles up and back from parking lot TH (Trail Head)and 9 miles from the visitors center. All uphill from the sand dunes area TH up to the pass but not very steep.

Lots of pretty windflowers along the stream, and great views of the dunes through the pass as you gain elevation. For the first 1/4 mile of the hike, there's a cool historic guided tour providing insight into lives of the pioneers that lived and passed through years ago. The trail seemed to end in a meadow, though we were hoping to go to the top. Don't forget to bring bug spray! The mosquitos are thick through the woods.

This is my favorite trail to run and is closest to Alamosa. The scenery changes a few times-rock walls, aspen forest, meadow, and desert before getting to the official end of the trail. There's miles of forest service road on the backside. The summit is up to the right after the trail ends. Follow the road up to the 'T' and head right up the two track. There's a camping spot and you'll have a great vista at the top

Probably the most beautiful hike I've completed to date. We didn't even plan on going the whole way up, but we couldn't stop because we were enjoying it so much. Winds it's way through various kinds of forest, ends in a meadow, and follows a nice mountain stream almost the entire way. Gradual incline --nothing too difficult. Beautiful views of the mountains and dunes. Awesome for birding!

A few other hikers were disappointed that the end was abrupt and didn't lead to the other side of the valley, but if you take a left right at the other end of the trail and walk up the hill for another 5 minutes, you can see the other side. We didn't expect the trail to traverse the entire way across so we weren't bothered by the end. Amazing hike!
