The Ultimate Guide: Top 10 Oregon Mountain Lakes Perfect for a Summer Swim

It’s almost summer, the snow has thawed, and the hiking trails have opened up, leading us back to our Alpine jewels. It’s no secret that Oregon houses some of the most stunning mountain lakes in the country. There’s nothing more satisfying than a crisp, refreshing dip after a day spent on Oregon’s extensive trails. Allow me to introduce you to the 10 best mountain lakes around, perfect for summer swimming.

1. Crater Lake

Located in southern Oregon inside the state’s only national park, Crater Lake is the deepest lake in the U.S. and exquisitely blue. Visit the Rim Village Cafe & Gifts on the south shore, then embark on the 7.1 miles Rim Drive for some of the most breathtaking views. Swimming is allowed at one spot, Cleetwood Cove, after taking the steep mile-long trail down to the lake. It’s worth the effort and the water’s azure clarity is nothing short of spectacular.

2. Wallowa Lake

Outside the charming little town of Joseph, Wallowa Lake is nestled at the base of Oregon’s “Little Switzerland,” the Wallowa Mountains. The State Park offers boat rentals and camping. While there, grab a bite at the Wallowa Lake Marina Grill. The glacial waters are best enjoyed in the peak summer heat. Enjoy a cooling dip but remember to respect the local wildlife.

3. Timothy Lake

Only a 90-minute drive southeast of downtown Portland, Timothy Lake is a great escape from the city buzz. PGE manages four different campgrounds around the lake – Gone Creek being locals’ favorite. Swimming, fishing, and paddling are popular here, with Mount Hood offering a sublime backdrop to your summer fun.

4. Sparks Lake

This gem lies just west of Bend, in the heart of Central Oregon’s Cascades. Base yourself at the Sparks Lake Day Use Area, and then hit the Ray Atkeson Loop Trail which circles the lake. After a sweaty hike, take a plunge into the cool, refreshing waters. Keep an eye out for busy beavers and playful river otters.

5. Devil’s Lake

Despite its menacing name, Devil’s Lake offers clear, turquoise waters that look just heavenly. It’s right at the Cascade Lakes Scenic Byway and due to its depth and lower elevation, is warmer than higher alpine lakes. As you’re in this area, treat yourself to lunch at Cascade Lakes Lodge before hitting the water.

6. Trillium Lake

This delightful lake, south of Mount Hood, offers the ultimate Oregon experience – verdant forests, high mountains, and crystal clear waters. Snap that iconic picture of Mount Hood mirrored on the lake. The Trillium Lake Campground is perfect for an overnight stay. Do check lake conditions before swimming as in late summer, the lake’s water level can drop quite low.

7. Elk Lake

Located along the Cascade Lakes Scenic Byway, Elk Lake boasts warm temperatures, clean waters, and stellar views of Mount Bachelor. The Elk Lake Resort offers paddleboarding, dining options, and even cozy cabins if you want to extend your stay.

8. Waldo Lake

One of the purest lakes in the world, Waldo Lake, provides an exceptional swimming experience. The lake is significantly less crowded due to motorized boat restrictions. You can access it via Highway 58 east of Eugene. The 20.2-mile Waldo Lake Trail is excellent if you’re up for cycling or hiking.

9. Green Lakes

While a longer hike is required to reach these beautiful glacier-fed lakes, the magnificence that awaits is worthy of the effort. The Green Lakes Trail starts off the Cascade Lakes Scenic Byway near Bend. After a good hike, there’s nothing quite refreshing as plunging into these emerald jewels.

10. Clear Lake

North of the Santiam Pass, Clear Lake mesmerizes visitors with its stunning clarity and lush surroundings. You can rent a rowboat from the Clear Lake Resort and explore the underwater forest preserved in the chilly waters from a volcanic eruption centuries ago.

It’s your turn now to go out, enjoy these breathtaking spots, and create unforgettable summer memories. Take that scenic drive, hike that trail, and swim in that pristine mountain lake. Here in the heart of Oregon, the greatest adventure always awaits just around the bend.
