We took the Reds Meadow Resort path back to Shuttle stop #10 which is recommended to get out because it is the last shuttle stop and usually fills up the shuttles leaving the area. The trail to the base of the Falls is closed now for 2018 for rerouting and restructuring and will reopen in 2019. Air quality was fine despite the fires but it was dry, hot and windy so bring enough water. The waterfall was beautiful and well worth the hike according to my seven year old! This trail has a steeper incline on the way back than to the Rainbow Falls trailhead so thats always an option to get to another shuttle stop too.
