The swimmable lakes
1) Kathleen Lake, Kluane — the Instagram lake. Freezing (10°C in August), sand beach, big mountains. Bring courage. 2) Marsh Lake — 40 minutes from Whitehorse, the local swim spot, tolerable by late July at maybe 18°C. Judas Creek beach has actual sand. 3) Chadburn Lake — 15 minutes from downtown Whitehorse, warmest in the area, no motorboats. 4) Bennett Lake at Carcross — the famous desert-and-lake combo, glacial and cold but the setting is unmatched.
The paddling three
5) Yukon River from Whitehorse to Lake Laberge — the classic 3-day canoe trip, current does the work, $200–300 for canoe rental including shuttle. 6) Kusawa Lake — an hour from town, sheltered bays, aurora viewing from the beach in shoulder season. 7) Nares Lake at Carcross — beginner-friendly, the surrounding Carcross Desert (world's smallest) is 20 minutes on foot. Combine paddle and dune-walk in a single afternoon.
Realistic expectations
Water in the Yukon peaks around 18–19°C in the shallowest lakes for about three weeks in late July and early August. Kluane-region lakes never get warm. Nobody swims after mid-August. What you get in exchange is empty beaches — you can genuinely have a mile of shoreline to yourself on a Tuesday. Bring a wetsuit if you actually want to swim laps; otherwise it is a jump-in-and-dry-in-the-sun situation.
