Backpacked 2 nights up at Dorthy Lake and had the place to ourselves. Gorgeous mountains, meadow and lakes. But the hike up was HARD. The creek crossing was doable, but after that the trail is washed out and finding it again was a challenge. And once on it, many places were washed out so we had to navigate over rock falls and gullies to pick up the trail again. The air was clear during the day, with some haze, but the smoke blew in at night. A beautiful place but not easy to get there.

7/16 Love this hike but only made it to the creek. The trail is washed out in many areas. Some hikers have left stacked rocks as markers but it can get confusing. Be prepared to traverse rocks and climb up and down large washed out sections. Lots of loose rocks. It took us double the time because of this. It makes the trail very difficult. Be prepared.

went june 5-6, 2018. tough hike with amazing views. be sure to call or check-in and ask about snow levels. the bridge is out so also ask about the water level in the creek. hike is well worth it.

one option is to just do the easy hike to where the bridge is out and enjoy the waterfall and rapids.
