Overview

Tucked along the park’s east side, Three Lakes is a ridge‑top cluster of small mountain lakes reached via the Laughingwater Creek Trail. Two lakes and the historic Three Lakes Patrol Cabin sit inside the park; a third, larger lake waits just 0.2 miles farther, just over the boundary in designated wilderness. It’s a quieter corner of the park—expect solitude, tall timber, and still water.

What You’ll See

  • Lakes ringed by old‑growth and subalpine forest, with seasonal wildflowers (bear grass is a standout year-to-year).
  • The characterful patrol cabin beside the first two lakes.
  • A short add‑on: continue about 0.5 miles beyond the third lake to an open area with a view of Mount Rainier when skies cooperate.

Trail Notes

The approach follows Laughingwater Creek before climbing steadily to the ridge. Near the end, the trail drops roughly 150 feet to the cabin and lakes—remember you’ll reclimb that on the way out. Many hikers press the extra 0.2 miles to the third (and least trampled) lake for a quieter shoreline.

Camping & Regulations

Three Lakes has designated backcountry camps (permits required). It’s one of the few park camps where stock is permitted. A pit toilet serves the area. Past reports note the bear pole isn’t always dependable—plan to use a bear canister or a solid hang. Collect water from the lakes or outlet streams and treat before drinking.

Wildlife

Deer are common, and hikers report frogs around the shore. Black bears are part of the neighborhood; store food properly. Occasional sightings of larger predators are possible in this wild, lightly traveled zone.

Conditions & Seasonality

Early season can linger here—snow patches and even ice on the lakes aren’t unusual. Summer brings bugs; expect mosquitoes around the water. The route is long and sustained, so budget time and energy accordingly.

Best Time to Visit

This area stays comparatively low‑traffic most days, but you’ll find the most solitude early in the day. If you want a Rainier view, aim for a clear‑weather window and continue beyond the third lake. For camping, late summer typically offers the most reliable, snow‑free travel, while being mindful of mosquitoes.

Pros

  • Quiet, remote lakes with a historic patrol cabin
  • Designated backcountry camps with a pit toilet; stock permitted

Cons

  • Strenuous, sustained climb of roughly 6 miles one-way
  • Mosquitoes are common in summer
  • Bear pole may be unreliable—bring your own storage solution

Tips

  • Continue 0.5 miles past the third lake for a clear view of Rainier.
  • The third lake is larger and less trampled—worth the extra 0.2 miles.
  • Bring a bear canister or plan a proper hang; the bear pole can be unreliable.
  • Expect a short 150‑foot descent to the lakes near the end—save energy for the return.
  • Early season can bring lingering ice; always treat lake or stream water.
