Henry Lake Trail is a 12.5 mile heavily trafficked out and back trail located near Almont, Colorado that features a lake and is rated as difficult. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible from June until September.
Directions from South Lottis Creek Campground: Hike south on South Lottis Trail, #428, about four miles from Lottis Creek Campground. Henry Lake Trail will veer to the right following South Lottis Creek.
Apparently there are 2 trails for Henry lake....
I'm with the first two posters, I have taken the longer rout myself a few times by taking the Lottie creek trail, but supposedly there is a shorter 2 mile rout coming from the southern side of Mount Henry that brings you up over the peak before you ascend down to the lake on the northern side of the peak. Either trail you take, you are sure to be surprised by the crystal clear waters and lush evergreens surrounding you at the base of the lake. Hoping to make it back up there this summer to do a little fishing and hiking the upper ridge around the lake(-:
I agree with first post. It is definitely more than 2 miles. Trail head is easy to miss if you aren't paying attention (I've done it once). Not far into the trail south lottis creek breaks off to the right. If you stay on main trail you will end up in Union Park, which is pretty, but not the lake. Great hike though!
Hang on speed racer. The trail to Lake Henry is 7 miles long and ascends over 3,000 feet in elevation. It is very rough like a riverbed with loose stones and large boulders everywhere. I have climbed it with a 50 pound backpack 7 times in the past 15 years, and while you are right in rating it difficult. I would add this. If you have to ask how difficult it is you cannot hike it. (It is much easier without a pack, but if you hike up without camping gear you will have to make the 14 mile round trip in one day)
If you can make it up you are in for a real treat. Spectacular views, crystal clear water, snowpack in July, and excellent fly fishing. You can take day hikes while you camp to the summit of Mt Henry, or the snowmelt ponds in the meadow above the lake that feed the stream/waterfall that enters the lake at the base of the peak.
