The deepest, bluest lake in America, filling a collapsed volcano.

There is no blue like Crater Lake's. It fills the caldera of Mount Mazama, a 12,000-foot volcano that erupted catastrophically and collapsed on itself about 7,700 years ago, leaving a vast bowl that slowly filled with snowmelt and rain. With no rivers flowing in or out, the water is astonishingly pure and deep — 1,943 feet, the deepest lake in the United States — and that depth and clarity scatter sunlight into a blue so saturated it barely looks real. Wizard Island, a cinder cone, rises from the western end like a detail someone painted in.
Most of the year the lake wears a thick coat of snow. The rim sits above 7,000 feet, and the park is one of the snowiest inhabited places in the country, averaging roughly 40 feet of snowfall a year — so much that the 33-mile Rim Drive isn't fully plowed open until well into summer. The payoff is a short, glorious season of overlooks, rim hikes, and impossibly clear water under blue sky, then a long white winter of snowshoeing along the rim.
A practical heads-up for 2026: the Cleetwood Cove Trail — the only legal way down to the lakeshore, and the only place to swim or catch the Wizard Island boat — is closed for a multi-year rehabilitation, so boat tours and island landings are suspended through 2028. And the East Rim Drive is under construction this season, so the rim isn't a complete drivable loop in 2026. The lake from the overlooks is still one of the great sights in the West — just plan around the closures and check current conditions before you go.
The park's main hub on the south rim, with the visitor center, café, and lodge — and the 1931 Sinnott Memorial Overlook built into the caldera wall, ~900 feet above the water.
Insider tipOpen to the rim year-round. Start here to orient yourself; a short paved path plus stairs reaches the overlook (not wheelchair accessible).
Plan a trip to this spot →The 33-mile loop circling the caldera, with 30-plus pullouts and ever-changing views of the lake, Wizard Island, and the surrounding Cascades.
Insider tipNormally fully open only mid-July through October. Note: in 2026 the East Rim Drive is closed for construction, so it isn't a complete loop this season — check current status.
Plan a trip to this spot →A west-rim pullout where a short, steep trail climbs to a historic fire lookout at nearly 8,000 feet — the park's classic sunset spot, looking straight down on Wizard Island.
Insider tipModerate but exposed at altitude; parking is limited, so arrive early for sunset and bring a wind layer.
Plan a trip to this spot →The volcanic cinder cone rising some 760 feet out of the lake, with a small crater at its top — the iconic detail in every Crater Lake photo.
Insider tipBoat tours and island landings are suspended through 2028 (no dock access during the Cleetwood rehab). For now, view it from the Watchman or Discovery Point.
Plan a trip to this spot →The Phantom Ship is a jagged little island that looks like a ghostly sailing vessel; the nearby Pinnacles are eerie 100-foot pumice spires — ancient volcanic gas vents exposed by erosion.
Insider tipAn easy combo off the southeast rim. Note the Pinnacles Road may be closed during the 2026 East Rim construction — verify before routing.
Plan a trip to this spot →The only legal route down to the lakeshore — a steep, strenuous switchback drop of about 700 feet to the water (and the only place you can legally swim or catch the boat).
Insider tipClosed for the 2026, 2027, and 2028 seasons for rehabilitation — no lakeshore access or swimming until it reopens around 2029. When open, treat the climb out like a mountain hike.
Plan a trip to this spot →Subalpine and snowy. Summers are short, cool, and dry — July and August highs only reach about 69°F, with nights in the low 40s (bring a jacket even in August). The rest of the year is buried: the rim averages roughly 40 feet of snowfall a year (one of the snowiest inhabited places in the country), and the snowpack lingers so deep that Rim Drive isn't plowed open until well into summer. Snow can fall in any month.
The South Entrance and Rim Village stay open all year; the rest is gated by snow most of the year.
The all-season access to Rim Village and the rim, plowed through winter for snowshoeing and snowy lake views. The way in for most of the year.
Closes by about November with the snow and reopens between mid-May and late June — the shorter, scenic northern approach.
Historic lodging and campgrounds inside the park are all seasonal; gateway towns cover the rest of the year.
The historic 1915 lodge perched right on the caldera rim at Rim Village, with a dining room and a stone-and-timber great hall overlooking the lake. Open roughly mid-May to mid-October.
Booking tipIt books far ahead for the short summer — reserve as early as you can.
Cabins and the large Mazama Campground near the South Entrance, about 7 miles below the rim, with a store and restaurant. Open roughly late May through September.
Booking tipReserve summer campsites on Recreation.gov; the cabins are the budget in-park alternative to the lodge.
Klamath Falls (the largest, ~1 hour south), plus Fort Klamath, Prospect, and the bigger hubs of Medford, Roseburg, and Bend for year-round lodging.
Booking tipBase in a gateway town in the shoulder seasons when in-park lodging is closed.
What does it cost, and is there timed entry?
$30 per vehicle in summer (good for 7 days), dropping to $20 in winter; $25 motorcycle, $15 per person. The park is cashless — bring a card. There's no timed-entry reservation.
When does Rim Drive fully open?
The South Entrance and Rim Village are open year-round, but the full 33-mile Rim Drive is normally open only mid-July through October because of snow. Note that in 2026 the East Rim Drive is also closed for construction, so the loop isn't complete this season — check current conditions.
Can I take a boat to Wizard Island or swim in the lake in 2026?
No. Boat tours, Wizard Island landings, and the Cleetwood Cove Trail (the only legal lake access and swim spot) are all closed for the 2026, 2027, and 2028 seasons for a major rehabilitation, expected to reopen around 2029. This year you enjoy the lake from the rim overlooks only.
How much snow does it really get?
Roughly 40 feet of snowfall a year — one of the snowiest inhabited places in the U.S. Most roads and all in-park lodging close for winter, but the South Entrance stays plowed to Rim Village for snowshoeing, cross-country skiing, and snowy rim views.
Why is the water so blue?
Crater Lake has no rivers flowing in or out — it's fed only by snow and rain, so there's almost no sediment, and at 1,943 feet it's extraordinarily deep and clear. That pure, deep water absorbs the longer red and yellow wavelengths and scatters the blue back to your eye.
How many days do I need?
One full day covers the rim overlooks and a short hike or two. Two days lets you drive the rim at leisure (closures permitting), catch sunrise and sunset, and add the Pinnacles or a waterfall walk.
Pick your vehicle, line up the stops on the way in and out, and carry the whole route in your pocket.
