Sebago Lake State Park

Maine's most popular camping destination on the shores of the state's deepest lake, with 250 campsites, sandy swimming beaches, boating, and the Portland Water District's source of supply stretching out from the campground.

Sebago Lake State Park

Field briefing

Sebago Lake State Park starts with access, not mileage.

Before you go

Sebago Lake is the gateway to Maine camping for Greater Portland families, and the 250-site campground at the lake's northeast corner is the hub of summer outdoor life in southern Maine.

Book early: reservations open in February, sites open up to 14 months in advance for some windows, and popular summer weekends fill within hours. The lake itself is the draw, with clear, deep water, two sandy swimming beaches, and excellent landlocked salmon fishing. The campground has water and electric hookups on 92 sites for RVs but remains a genuine state-park setting rather than a resort.

Best window
July and August when the lake warms enough for swimming (typically low to mid-70s F) and the campground operates at full capacity.
Signature routes
Witch Cove Beach and Naples Beach swimming, Sebago Lake paddling and boating

When to go

Weather, crowds, and what the season changes about the trip.

Spring

Low crowds

Cool with ice-out on Sebago Lake typically in late March or April. The campground opens in May, and spring fishing for landlocked salmon and lake trout begins as soon as the ice is gone.

Pack Layers for cool lakeside mornings, fishing gear if targeting early-season salmon, and a camp reservation if opening weekend is the goal.

Summer

Peak crowds

Warm and sunny, with lake surface temps reaching the low 70s F by late July. The campground is at or near capacity most of July and August; reserve early.

Pack Swimsuit and water toys for the beach, sunscreen for open lake swimming, and a camp reservation booked as early as possible in the season.

Fall

Moderate crowds

Crisp and colorful with foliage peaking in October. The campground is open through Columbus Day weekend (mid-October), and fall is a quieter way to enjoy the lake.

Pack Layers for cool evenings, a kayak or canoe for fall foliage paddling, and morning fishing for landlocked salmon feeding in cooler water.

Winter

Low crowds

The campground is closed November through April. Ice fishing for salmon, togue, and white perch is popular when the lake freezes, typically by January.

Pack Ice fishing gear, appropriate cold-weather insulation, and a check on ice conditions before venturing onto the lake.

Top things to do

  • Witch Cove Beach and Naples Beach swimming

    The campground side of the park has two guarded swimming beaches, Witch Cove Beach and Naples Beach, on the northeast corner of Sebago Lake, with sandy bottoms and lifeguards on duty in season.

  • Sebago Lake paddling and boating

    Sebago Lake is Maine's second-largest and deepest lake (316 feet at its deepest point). Canoe and kayak access from the campground puts paddlers onto a lake with more than 45 miles of shoreline and Sebago's notoriously clear water.

  • Landlocked Atlantic salmon and lake trout fishing

    Sebago Lake is Maine's most celebrated landlocked salmon fishery. The salmon were native to the lake and the Presumpscot River, and the population is sustained by active management. Spring and fall are the best seasons for trolling near the surface.

  • Nature center and evening programs

    The park's nature center runs summer interpretive programs for campers and day visitors, covering the lake's ecology and Maine wildlife. Evening campfire programs are offered throughout the summer season.
