6 Washington alpine lake hikes worth every switchback this summer
Some of Washington’s best lakes are visible from a parking lot. These six are not.
Every one of them demands a real climb — sweat, switchbacks, maybe a rocky scramble near the end — and every one pays it back with water so blue it looks edited. Here’s where to point your boots this summer, ranked loosely from warm-up to gut-check.

Talapus and Olallie Lakes — bring the whole crew
Not every alpine lake needs to hurt. Talapus and Olallie Lakes run 5.8 miles round trip with about 1,210 feet of elevation gain on a steady, well-graded trail off I-90.
It’s an easy entry point for families or anyone breaking in new boots, and the payoff — two lakes instead of one — doesn’t feel like a consolation prize. You’re on Mount Baker-Snoqualmie National Forest land here, so a Northwest Forest Pass needs to be on your dash.

Snow Lake — the one everyone eventually does
Step it up from here. Snow Lake runs 6.7 miles round trip with roughly 1,686 feet of gain, climbing out of the Alpental ski area alongside the South Fork Snoqualmie River.
It’s also one of the most popular trails in the entire Alpine Lakes Wilderness, so don’t expect solitude — expect a genuinely great payoff instead. Waterfalls line the switchbacks on the way up, and the lake sits in a granite bowl big enough to wander for an afternoon. Same Northwest Forest Pass rule applies at the trailhead.
Lake Angeles — Olympic National Park’s alpine answer
Most of Olympic National Park’s fame comes from rainforest and coastline, so Lake Angeles tends to surprise people. From the Heart O’ the Hills trailhead near Port Angeles, it’s about 7.2 miles round trip with 2,483 feet of gain to a lake tucked beneath Klahhane Ridge.
Pair it with a day in Port Angeles or add it to a bigger run through our guide to the best hikes in Olympic National Park. This one’s inside the national park, so a Northwest Forest Pass won’t cover you — you’ll need an America the Beautiful Pass or the standard park entrance fee.
Rachel Lake — short on paper, brutal in practice
Don’t let the mileage fool you. Rachel Lake runs around 9 miles round trip with roughly 2,500 feet of gain, but the number hides the real story: the first 2.5 miles are easy, then the final mile packs in about 1,200 feet on a rooty, rocky scramble.
It’s the kind of climb that makes you question your life choices for twenty minutes and then hands you a lake worth every complaint. Keep going to Rampart Lakes if your legs have anything left. Northwest Forest Pass required — this one’s Okanogan-Wenatchee National Forest land.
Lake Ingalls — the view that stops conversations
This is the step up. Lake Ingalls via the Esmeralda Basin trailhead runs about 9.1 miles round trip with 2,857 feet of gain, and it earns its “hard” rating honestly.
The reward is a turquoise lake sitting directly beneath Mount Stuart’s north face, one of the more dramatic mountain backdrops in the Cascades. Go now for wildflower-heavy meadows on the approach — come back in October if you want to see the surrounding larches turn gold. Same Northwest Forest Pass rule applies.

Blanca Lake — the glacier-blue finale
Save this one for when you’re in real hiking shape. Blanca Lake runs about 7.7 miles round trip with 3,385 feet of elevation gain, steep enough that most hikers rank it among the toughest day hikes in the Cascades.
The color is the reason people keep coming back: glacial meltwater feeds the lake a turquoise-green shade that looks almost unreal against the dark forest below. Views toward the Monte Cristo peaks open up near the top, right before the trail drops steeply to the shoreline. It sits on Mount Baker-Snoqualmie National Forest land, so bring that Northwest Forest Pass.
Six lakes, six very different amounts of suffering, all worth it in the end. Which one’s earning your sweat first?
Trip tips: grab a rental car to reach these trailheads, lock in your hotel before the good rooms are gone, or skip both and book a camper van instead.
