There's a bit of a scramble up the last bit of trail to get to Cleo's Bath but it's worth it. You'll find a nice little pool to have a cool down swim or just to dip your feet in, before heading back towards the lake. Note: The water levels can be extremely high during the spring runoff so swimming may not be an option if you visit at this time.

There was a lot of controversy around the damming of the Tuolumne River and flooding the Hetch Hetchy valley over 100 years ago. The famous naturalist John Muir held it up as an equal to nearby Yosemite Valley, and though only a few grainy photos remain if definitely looks like he had a point. These days you can still be stunned by the vertical granite walls, dramatic waterfalls, and towering domes.
