Which pool fits your mood this month? Grab a towel and plan your next cold plunge.
1. North Fork Falls, Emigrant Gap, CA
Two waterfalls, two pools, one very happy swimmer. That is the deal at North Fork Falls in Placer County, California.
The upper cascade drops into a small, deep pocket of water. From there it slides over rock into a wider lower pool that feels made for floating.
Cedar, pine, and fir trees shade the banks, so the air stays cool even in August. The setting is quiet, which is rare for a summer waterfall.
Some visitors leap from the ledges into the deeper sections. I would test depth first, because the surrounding rock can be sharp and slick.
A short trail gets you down to the water. Wear shoes with grip and take your time on the descent.
Weekday mornings feel almost private here. Go early, claim a rock, and let the roar of the falls do the talking.

Turquoise water that looks unreal until you touch it. Emerald Bay State Park sits on the California side of Lake Tahoe, and the color alone justifies the drive.
Reaching the beach means hiking roughly a mile down from the highway. The views on that descent are ridiculous, and yes, you climb back up afterward.
Paddleboards and kayaks rule the shoreline. Paddlers often aim for Fannette Island, the only island in all of Lake Tahoe.
Historic Vikingsholm sits near the shore, with tours offered seasonally. It adds a Scandinavian twist to your beach day.
The bay is also designated an Underwater State Park. Divers explore sunken vessels below the surface, which few lake swimmers ever expect.
