Here is the girls celebrating making it up the switchbacks to finally reach the upper lake. It is not easy at all. The trails are only about a foot wide and very steep drop offs. It is almost 7 miles to get to the upper lake so all in all we walked over 13 miles. It was torture on the way back. We started the hike at about 11 a.m. and got back to the van at 9 p.m.
