For more details on the hot springs click on an item I wrote for RV Short Stops.
We stayed at Burgdorf Campground, and bicycled to the hot springs, less than a mile away. (The Payette NF website indicated this campground was close, but in fact it re-opened in mid-June.) It fills quickly–there are only three (3) boondock sites available. Water and vault toilet only–no other amenities. When we camped there was plenty of free firewood from recently cut dead trees. $10/night (or $5 w/senior pass).
