Beautiful! Went counterclockwise, I’m out of shape...

Got to the trailhead around 7:30 on a Saturday and there were only a few spots left. Did the trail counterclockwise (Devil Thumb lake first) which led to a pretty challenging climb up the pass (carried 35lb packs). Pretty crowded up to that point, but then it dropped off. We camped right by King Lake which was beautiful but really exposed. Fortunately there was no lightening but we had to guy out every line on the tent due to high winds - kinda sketchy. Beautiful hike with plenty to explore off the trail too.

My first real Colorado hike. So beautiful and everything I hoped for and more. I recommend going clockwise (King's lake first), as it's a more gradual ascent compared to the other way.

Started kind of early in the morning, so took the 9AM shuttle from Nederland. Turned out to be a great idea as many people who parked on the side of the road were already hiking at least a mile if not more just to reach the shuttle bus drop off point.
Opted to run the loop in a counterclockwise direction. I think that is a much better way to go through this route. One reason is the morning sun provided great views along Devils Thumb Trail. Second: King Lake Trail drops below tree line pretty quickly so a potential afternoon thunderstorm would find you in the protection of a dense forest.
Otherwise not many people on the trails: every few minutes a group.
Fortunately I was able to complete the loop before the thunderstorm, that just moved in as the shuttle bus took be back to the RTD parking lot in Nederland.
Sunny day and an awesome experience. The views were spectacular!!! I can only recommend this loop.

One of the most beautiful hikes I've done! Get there early if you want a good parking spot. Passed by three beautiful lakes, waterfalls and met some fun people along the way! Highly recommend for an endurance hike!

Amazing hike!! Awe-inspiring views and ever-changing scenery. I have done a lot of hiking in CO and this is possibly my favorite.. Most go CW; this lends itself to a milder incline. Trails are very well marked. Little bugs, virtually no snow. Arrive earlier than you think; it was already slim pickings at 6:45am this morning.

We camped this loop over weekend and took backpacks. Nice trip, beautiful scenery, lovely flowers and not too busy. First night in Devil's thumb lake, second at Kings lake. I might reverse that if I had to do it again, because Devil's Thumb pass was a bitch much with a full pack at altitude and divide, but still highly recommended!

Wonderful, beautiful hike. However, with the loop we hit a glacier with no way around it (July 2017). We had to slide down it, but I would not recommend as it was very unsafe. I am not sure how everyone else is doing this loop as I didn't see any tracks on this glacier. I would love to come back for fishing.

Hands down the best hike I've been on this summer. I've done a majority of the hikes in the Nederland's area and this easily tops the list at number 1 in my opinion. It has the best components of every hike. It took me most of the day, about 10 hours in all, but that was with talking to other campers and hikers along the way, plus a few extra stops to rest. The views along the high lonesome Trail makes it all worth it, especially when overlooking Devils thumb lake and eventually kings lake. 10/10 would recommend this for well seasoned hikers.

Hiked May 19. Still tons of snow. Still fairly compact in the shade, started getting slushy in the sunshine. Snowshoes would have been really helpful. Hike was beautiful regardless. Amazing vistas. Didn't see another person after the 1st mile or so. Would have definitely lost the trail in the snow several times over if it hadn't been for some day or so old tracks. Saw a few mountain lion tracks. Will definitely repeat in summer.

This is an ambitious hike that has everything!!!! Water (in season), wildflowers, meadows, rugged mtn views, lakes, aspen, evergreen, you name it.

It was breathtaking in every way. wear waterproof shoes and get there early. We went during the week and saw 3 other people!

I've hiked this trail several times,early autumn and early spring. I love this trail for it's rugged beauty. In early autumn the aspens were golden yellow and the water falls were incredible. In early spring I had my three sons and the snow was still fairly deep. We had to go off train & over the ridge to avoid deep snow. The waterfalls were absolutely amazing. The spring melt made for a spectacular show. Great for dogs, a little tough for young kids. It is my favorite place.

The Devils Thumb trail is amazing to run and provides a great variety of conditions to keep it interesting. Technical conditions range from dirt single track to loose rock. There are some challenging hills, but these are usually followed by flat stretches to help recover before the next hill.
The trail to the lake is about 6 miles from TH. An additional mile can be tacked on by pushing up to the Continental Divide. That mile is tough with decent elevation gain. But it is worth it just on the view alone.
Do arrive at the TH (fork at July 4th Road and Hessie) early as roadside parking is limited and does fill up fast towards late morning. Additionally, there are very few people on the trail that early for the outbound leg.
Bring a camera.

You can make an excellent ~17 mile loop out of this trail if you continue up after Devil's Thumb Lake up to the continental divide, head south for about 2 miles then drop down to the King's Lake trail which will take you back to the Hessie trail head. Running I spent a little under 5 hours and it does add another +1,200 vertical feet to get up to the divide, but the view are worth it. I originally found this trail on the blog I linked to.

Beautiful hike once you get past the first mile or so. Not sure why it's rated difficult. I would give it a difficult if it was to the pass. Arrive at the trail head early if you like solitude.

Somewhat technical. Breathtaking scenerey (literally). Phenomenal trail. The only downside was the huge amount of people on the first mile or two of the trail.
