Lower Twin Lake is a great destination for a short walk, and it is an especially good choice for families. The hike is not very challenging, and the well-built trail winds through beautiful old-growth forests before leading to a rewarding lake that is great for swimming.

The hike begins on the far left edge of the Frog Lake Sno-Park under the blue blazes that mark the ski trail in the winter. The route begins as a gentle but persistent climb to a ridge through towering fir trees and a rich understory of huckleberry bushes, following the Pacific Crest Trail. Limited views of Mount Hood can be seen through the trees along the upper sections of the trail. On a saddle at the top of the ridge, at a clearly marked junction, head right toward Twin Lakes. From here the trail drops into the Twin Lakes Basin. Soon, filtered views of the lake appear, and after a half-mile, turn right at another junction toward multiple campsites in a clearing along the lake shore. This area is a good place to stop for lunch and a swim. An unmarked and obvious trail leads around the lake, sticking close to the shoreline. Approximately a dozen unmarked and well-developed backcountry campsites, most within view of the lake, dot the trail around the lake.

Hiking to Lower twin lake is easy and relaxing. You can keep going for more to the other lake, the butte, or even further up the PCT. My time spent here on video:
Great lake for enjoying the sun and water on a hot day. I went on a Sunday afternoon and it was somewhat busy, though many campsites were open. The lower lake was prettier than I expected. The Upper Lake was much more tranquil (not a soul in sight nor to be heard), and provided a glimpse of the top of Mt Hood. Well worth the effort, and I imagine this place would be a great overnight destination. The only downside of this trail was the trash at the trailhead- bins were overflowing, and the restrooms had bas of garbage inside and out. Oh, and no toilet paper in the restrooms. When enjoying this trail (and all outdoor spaces, really), please remember to pack out what you pack in.
mistakenly only did Frog Lake loop which is down the gravel road. Next time need to follow PCT out of parking area on left side.
