Crumbaugh Lake Trail is a 2.4 mile out and back trail located near Old Station, CA that features a lake and is good for all skill levels. The trail is primarily used for hiking and is accessible from July until September.
This is a nice hike to bring the little ones on. It's fairly easy & short, passes Cold Boiling Lake (look for bubbles) before reaching Crumbaugh Lake, which is surrounded by meadows. If you have time & energy, you can take the cut-off at Cold Boiling Lake & take the back-way in to Bumpass Hell.
