The fourth campground in the area is about a mile away on Scout Lake. The lake is small but clear and warms up quickly for swimming. This is the local swimming hole for the Sisters community, but rarely is crowded. The campsites are perfect for medium size groups. All the sites can be reserved through the national reservation system.
Some sites are for double groups and one for a triple party.
But the whole campground can be reserved if you do so soon enough. In a year when the reservoirs on the west side of the Cascades are low, this should be a very popular area .
