Big Lake South State Recreation Site sits along the southern shore of Big Lake, one of the most popular recreational lakes in Alaska’s Matanuska-Susitna Valley. Just a short drive from Wasilla, this recreation site offers easy access to Big Lake’s warm, shallow waters — a rarity in Alaska that makes it a favorite for swimming, kayaking, and canoeing during summer months.

The recreation site serves as a launch point for boating and fishing on Big Lake, where anglers target rainbow trout, landlocked salmon, and northern pike. A public boat launch makes it simple to get out on the water, and the lake’s size provides plenty of room for waterskiing and jet skiing alongside quieter paddle sports.

During winter, the frozen lake transforms into a hub for ice fishing, snowmachining, and cross-country skiing. The surrounding birch and spruce forests frame views of the Alaska Range and Denali on clear days, adding a dramatic backdrop to any visit.

Picnic areas and day-use facilities make this a solid stop for families looking to spend an afternoon lakeside without a long commitment. The site draws a loyal local crowd, reflected in its 4.3-star rating across 71 reviews, with visitors consistently praising the waterfront access and well-maintained grounds.

The best time to visit is June through August, when long daylight hours and warm temperatures make the lake ideal for swimming and paddling. Arrive early on summer weekends — this is one of the valley’s most popular spots, and parking fills quickly.
