Didn't complete the trail, made it to the gnarly cascade and crossed, following cairins and finding the san isabel national forest sign and a trail that literally turned into a creek 20 yards later and was overgrown, turned back and camped by the cascades, still a great spot in the canyon.

Also, there are a handful of blowdowns, sketchy creek crossings, and as of the day we went, a moderate rock slide that obscures the trail about 3 miles up the canyon, creating moderate exposure...this trail needs work.

Great trail. Due to run off, water crossing was challenging. Start early, this is a long trail of you plan to go the full distance.

This is a fun trail but heads up that the water is high and water crossings are a no go if you are carrying a little one. Normally it would be okay, but with all the rain and run off makes it unsafe if you have a kiddo on your back. You can still do over a mile but the trail will have to wait until later in the summer when crossings are easier. Completely fine for individuals without kids. Lots of downed trees right now.

Needs a lot of work.

This trail has it all. Most of the trail is shaded which was good on a warm fall day. A small water fall is approximately 4 miles up the trail. It is 6.63 miles to the summit. Awesome views throughout the hike. If you plan on reaching the summit get an early start. I highly recommend this trail.

Loved this hike! Brought my brother from California and he had no problem with the altitude. Would love to do it again in the fall. We were the only folks on the trail!

I hiked up from Lower Greenhorn trail marker 5 miles before lightening & thunder turned me back.
a great hike...easy to lose the trail at the river crossings but rock signs will show you if u look for them.
I will definitely be trying to summit again soon.
this was my 1st scouting expedition on July 24, 2016.

Started at the trail Head near RYE CO. Trail solid until you hit a section the has been washed out from the flood of June 2013. The force that came down moved the river causing the trail to end in at least 3 spots. Got off trail more than once but keep to a 90 degree crossing the river and you'll find it again. Once too the rock slid on the north side of the canyon the trail is washed out again go straight across the river. It was high last week you need to pick a safe spot, look for rock piles to lead your way. Steady up hill to the avalanche areas which you traverse like 4 times until you hit timberline. Your close at this point. Trail is a solid 9 or 10 miles one way well worth it. A few good camp spots along the way or have someone pick you up on the east side trail head at the end of HWY 369.. GREAT HIKE

Starting out of Rye at around 6 in the morning with a great deal of overcast. With a gradual gain in elevation for the first 2 miles trees crowd the trail before it drops down to the creek a few miles in. This is when you start to break from tree cover and start attacking the switch backs on the southeast side of the ridge. You then come to what is known as the rock slides, capturing great views of the rest of the trail. The rock slide is short but very sweet that is for sure. You then drop down to the creek again and begin the final accent towards the top. It is the hardest few miles of the trail as you will experience the most elevation change. Switch backs and trees is something that should be expected for these last few miles. After repeating the switch backs a few hours later you will come upon a avalanche shoot where trees have been downed everywhere. You can see the top and the rest is history as you are within thirty minutes from the top. Enjoy the hike and respect the beauty of this amazing trail and hike!

Made it to the top from the west side (Ophir Creek) which is a short 4 miles or so. Have only made it to tree line from the east side (Rye, CO) along Greenhorn Creek. The east hike is more challenging because of the distance which is about 11 miles one way. This is a very pleasant hike in that it is mostly covered by forest until you get to treeline. Cell coverage is spotty. Watch for lightning.
