A simple walk through some beautiful forest!! Devil's Postpile was too cool with a nice little shaded area to eat lunch before the rest of the hike to Rainbow Falls. The trail is very sandy and therefore can tire you out a bit so just pace yourself because, although not difficult, we met with a few older folks on the trail that didn't find it to be so easy -- if that's the case for you there are two spots to cut the hike short and head up to Reds Meadow Resort, and you'll still see some amazing sights! Myself, my wife, my 12 year old daughter and 6 year old son did great but we were certainly tired at the end! Rainbow Falls is breathtaking, a great reward at the end of the hike! Just save your strength since you have to then hike back up and out 1.3 miles to the resort and/or shuttle.
