Ponderosa State Park near McCall sits on a peninsula that reaches into Payette Lake, covered in old-growth ponderosa pine. The forest, lake and mountain scenery make it one of the most beautiful and popular parks in Idaho. Summer visitors enjoy swimming, boating, fishing and hiking along the shoreline trails, while winter turns the park into a destination for Nordic skiing. Campgrounds and picnic areas make it easy to enjoy the lake for a day or a week. A $5 per-vehicle entry fee applies, and camping costs $15 to $50 per night. Reserve early for summer weekends, when the park is at its busiest.
