About Big Lake South
Big Lake South State Recreation Site provides boat launch access to the south shore of Big Lake — one of the Mat-Su Valley’s premier recreation lakes. The site offers day-use facilities and serves as a primary access point for fishing, boating, and watercraft recreation on the lake.
Big Lake South State Recreation Site on the southern shore of Big Lake provides camping and boat launch access to the lake’s warmer, more sheltered waters. The Mat-Su Valley is Alaska’s fastest-growing region — former farmland (this was a 1930s agricultural colony) now supports a suburban population serving Anchorage. Despite growth, the area retains Alaska’s wild character: moose regularly wander through campgrounds.
Things to Do
Boat launching, fishing for rainbow trout and landlocked salmon, waterskiing, jet skiing, picnicking, and accessing the lake for summer recreation. Winter brings ice fishing and snowmobile access.
Camping (27 sites), fishing, boating, swimming (the south shore warms faster), wildlife watching for moose, and using as a base for Mat-Su Valley exploration.
Plan Your Visit
Big Lake South is 60 miles north of Anchorage via the Parks Highway — making it one of the most accessible recreation sites near Alaska’s largest city. Big Lake itself is a major float plane base and fishing destination. Rainbow trout, arctic char, and landlocked salmon are caught year-round. Ice fishing in winter attracts thousands. The Mat-Su Valley (surrounding area) is Alaska’s fastest-growing region. Fire danger is high in summer; check conditions.
Insider Tips

Best Time to Visit
June-July: Peak fishing and longest daylight (20+ hours). August: Silver salmon runs begin. Winter: Ice fishing and aurora viewing — Big Lake’s dark skies produce excellent Northern Lights displays. September: Fall colors and moose rutting season (keep distance!).
