Great, easy one night overnight to Echo Lake. We arrived at the trailhead at 8:00 AM Saturday morning with plenty of parking left. The trail to Echo Lake is straightforward and mostly in the shade, which made for a very pleasant hike even with overnight packs.
We found a good spot to camp with ample room for two tents and two hammocks and easy access to the lake for floating and swimming. Bugs were annoying but not as bad as I thought they would be. Hardly anyone else camping at the lake, so it was a quiet place to enjoy a sunny weekend.
