Grover Hot Springs State Park, California
This is an awesome State Park located in Markleeville, CA. It's in close proximity to Lake Tahoe, CA, and offers many great day hikes for all ability levels in the area. Cycling, both road and mountain, are a personal favorite of mine, and I see many fisherman in the Carson River.. May through early October have been my favorite times of year to go. However, I have camped there and used the hot springs in February.
