Marsh Lake Territorial Campground is a road-accessible Yukon Government campground situated in the Southern Lakes region, roughly 25 miles south of Whitehorse along the Alaska Highway.

The campground is laid out in two loops, with many sites positioned directly beside the lake, including access to both open waterfront spots and secluded rocky beaches. A short trail and footbridge connect campers to a popular sandy beach and recreation site.

The area carries deep cultural significance — the Marsh Lake people held their main camp and potlatch house here, and both the Southern Tutchone name Tàkádàdhà and the Tagish name Sāa Tl'áh Ni reference the lake's notable sandy beach.

Each spring, nearby M'Clintock Bay draws thousands of trumpeter swans and other migratory waterbirds, and the Swan Haven Interpretive Centre is open in April for those wanting to learn more.

The campground is extremely popular on weekends and fills quickly, so arriving early or planning ahead is strongly advised.
