Frequently asked questions about swimming in Crater Lake

What part of Crater Lake can you swim in?

There are only two places you can swim in Crater Lake National Park.

The first is Cleetwood Cove, accessible only by hiking down the Cleetwood Cove trail.

The other area to swim is off of Wizard Island, a small island in the middle of Crater Lake. To get to Wizard Island you have to first hike the Cleetwood Cove trail, and then take a boat to Wizard Island.

Is Crater Lake too cold to swim in?

Crater Lake is quite chilly! But if it is ‘too’ cold to swim in depends on the individual. If you’ve swam in other alpine lakes before, this is pretty similar.

In the summer months the surface water temperature of Crater Lake is 55-60°F. The water will warmest closest to the surface and in shallower water.

The temperature of the water gets colder the deeper it gets. The average temperature when you reach 300ft is 38°F!

But since you can only swim in Crater Lake in the summer when Cleetwood Cove is accessible, the hike down should get you in a sweat.

I personally found it quite refreshing when I was there! Hopefully you’re at Crater Lake on a warm, sunny day and you can soak up the sun for a little bit before hopping into the lake.

For safety, be sure to stick close by to the shore in case the water gets too cold for you and you can easily get yourself out of the water.

How clean is Crater Lake water?

Crater Lake’s water comes only from rain and snowfall.

It is actually one of the purest lakes in the world, so you can rest assured that it is very clean and safe to swim in!

When can you swim in Crater Lake?

The short answer to this question is: late June – October. But this depends on any late or early snowfall that may close the Cleetwood Cove trail, or the Rim drive that you need to drive to get to the trail.

Each year the trail opens sometimes in late June and closes again sometime in October.

You can only swim in Crater Lake when the Cleetwood Cove trail is open. The Rim Drive also must be open in order to access the Cleetwood Cove trail.

Stay up to date on current road and trail conditions on the Crater Lake National Park Service website.

Hiking the Cleetwood Cove trail to swim in Crater Lake

To access the lake’s shores you will have to hike down via the Cleetwood Cove trail.

This trail is 2.2 miles roundtrip with 700 elevation loss/gain. Find a map and recent reviews here.

Expect the hike to take 30-45 minutes each way depending on your fitness level and hiking speed. It will take a little longer coming back up due to the steepness than it took going down.

This hike can get really crowded! Want to beat the crowds and have calmer water? Go early in the morning! Also try to go on a weekday as opposed to a weekend for less crowds.

There is plenty of parking at the trailhead as well as pit toilets to use. I recommend already starting on the trail with your bathing suit on since there are no changing areas around, and I wouldn’t suggest changing in the pit toilets either!

The trail has many switchbacks going down and it is quite steep and sandy. Wear hiking boots or shoes with good grip so you do not slip. You will lose all the elevation to make it down to the lake, so be prepared for the steep hike back up!

The hike down is really beautiful, with glimpses of the vivid blue color of the lake popping out between the trees.

Bring 1 liter of water a person, especially during hot days, and maybe pack a lunch that you can enjoy down at the water’s edge. But be sure to never feed wildlife and pack out all of your trash!

Note that dogs are not allowed on this trail.

The cliff jump at Cleetwood Cove

There is a 35 foot cliff jump located at Cleetwood Cove, sometimes referred to as ‘Jumping Rock’. If you’re like me and always up for a thrill, I highly suggest it! I thought the jump was really fun and I felt really exhilarated afterwards.

However, a big word of warning about cliff jumping. As someone sitting here April of 2023 actively recovering from a different cliff jumping accident where I fractured 2 vertebrae in Guatemala.. I don’t mean to scare you, just make sure you exercise caution! Your landing position is key.

You should always land a jump in a ‘pencil’ position with your feet first. And I feel like this goes without saying but you need to know how to swim before you jump in.

If you’re not feeling the cliff jump- that’s okay! You can also easily just slide in the water or do a little jump off a shorter rock.
