If you park at the upper lot, prior to entering the park, you've got a 2 mile walk to Brainard lake plus a mile to Long Lake. Get there early in the morning, late in the afternoon or during the week in order to park near Brainard Lake. The hike to Lake Isabella is a beauty! Not much grade increase until the last quarter of a mile. Pay attention to all of the warnings about the mosquitos. They are plentiful and huge (as in carry of small cattle huge!) Jeff Purcell (653) 18 days ago N/A: 14 Completed 14 Reviews Great hike. A must do. Go early in the summer months if the road to Brainard Lake is open. If so you can drive to Lake Brainard and save walking a few miles extra down the paved road. Isabelle is on the same route as going to Long Lake in case you have any trouble determining which direction to go as there are several roads around the Brainard recreation area. We hiked all the way to the little pond at the basin just past Lake Isabelle. Great views and a very nice hike. Chat Coats (294) 24 days ago N/A: 13 Completed 8 Reviews Great, scenic and very gradual hike to a breathtaking mountain lake expanse. Dallas Bernard (106) about 1 month ago N/A: 2 Completed 1 Reviews Awesome hike, worth every moment! 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 (522) about 1 year ago N/A: 12 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.
