Easy and scenic along the entire trail. Take bug spray along w/ or you will be feasted upon. Jenna Lampro (120) about 1 month ago N/A: 17 Completed 1 Reviews Incredible! Still a lot of snow on the trail and made getting to lake a bit difficult but it was worth it! The road to the trail head is still closed so we had to walk on the road for about a mile. Michael Cox (499) 11 months ago N/A: 11 Completed 8 Reviews Nice trail. Tons of mosquitoes. The lake was quite low. Valerie Doubleday (272) almost 2 years ago N/A: 7 Completed 7 Reviews Absolutely breathtaking hike. For the most part it's fairly easy. Multiple gorgeous places to take pictures or stop for a picnic. I recommend going in late June or early July to see both the wildflowers and the waterfall. If you decide to pass the lake and continue on to Pawnee Pass be aware that it does get more difficult. This trail can be crowded so go during the week if possible. Worth paying the fee at Brainard Lake entrance. One of the most beautiful places ever.
