South Rolly Lake is a 108-acre lake located within Nancy Lake State Recreation Area, approximately 67 miles north of Anchorage via Parks Highway. Access the lake by turning west onto Nancy Lake Parkway at Mile 67. 3 of Parks Highway, then driving 6.

5 miles to South Rolly Lake Campground at the road's end. The lake features an undeveloped boat launch accessible directly from the campground, with some campsites positioned right on the shoreline.

Only non-motorized watercraft and electric motors are permitted on the lake. The campground offers convenient amenities including canoe and kayak rentals through Tippecanoe outfitters, located within the campground itself.

South Rolly Lake connects to two smaller lakes via a channel, creating opportunities for extended paddling routes that function as a mini canoe trail system.

The lake reaches a maximum depth of 63 feet with a mean depth of 27 feet, providing ample water for paddling throughout the season.

Wildlife viewing opportunities include beavers, waterfowl such as loons and grebes, occasional swans, and moose in the surrounding area.

The lake is stocked with rainbow trout and also contains northern pike, making it popular among anglers who combine fishing with their paddling activities.

The campground provides practical support for paddlers with 98 campsites, picnic tables, fire rings, water pumps, and restroom facilities. A dock extends into the lake for easy water access.

The heavily forested setting creates a wilderness atmosphere despite the developed campground amenities. Additional paddling opportunities exist nearby, with short drives from the campground leading to access points for North Rolly, Rhein, and Tanaina lakes.

The area also connects to the more extensive Nancy Lake canoe trail system, including the popular Lynx Lake Loop trail accessible from Tanaina Lake.

The recreation area operates seasonally, with optimal paddling conditions typically occurring from late May through early September. All shoreline around South Rolly Lake is public property within the state recreation area.
