8 Best Natural Swimming Spots In And Around Portland

On a hot summer day, there’s nothing like cooling off in a natural swimming hole. Whether you’re escaping the city heat or just want to float under the trees for an afternoon, the Portland area is full of natural swimming spots that offer everything from rugged river adventures to calm lakefront lounging. Below are 8 of the best places to swim in nature.

1. High Rocks Park – Gladstone

High Rocks Park, located along the Clackamas River in Gladstone, is a classic local swimming hole just 20 minutes from Portland. The rocky cliffs and deep swimming areas attract experienced swimmers and divers seeking a thrilling rush. The park also features grassy areas for relaxation, although it can get busy on warm weekends. 

While there are sometimes lifeguards on duty in the summer, river currents can be strong and unpredictable, so it’s best suited for strong swimmers.

2. Blue Lake Regional Park – Fairview

A calm, spring-fed lake just outside the city, Blue Lake Regional Park in Fairview offers one of the most family-friendly swimming spots near Portland. The lake features a roped-off swim zone, a sandy beach area, and shaded picnic spots with ample space to spread out. Kids will love the splash pad and playground, while adults can enjoy a slow float or lakeside picnic. 

Be sure to check the water quality online before heading out, as swimming is occasionally restricted due to algae blooms.

3. Oxbow Regional Park – Gresham

Oxbow Regional Park is a peaceful forested retreat located about 45 minutes from downtown Portland, nestled along a wide bend of the Sandy River. Its beaches offer numerous access points for wading, swimming, and relaxing under the shade of the trees. The park is part of a protected natural area with wildlife, trails, and campsites, so it’s easy to make a full day, or even a weekend, out of a visit. While the river current can vary, there are calmer pockets that are suitable for casual swimmers and families.

4. Dabney State Recreation Area – Troutdale

Just downstream from Oxbow, Dabney State Recreation Area offers an easier-access alternative along the Sandy River. With open lawns, picnic tables, and a wide beach area, it’s a perfect destination for groups and families. The water tends to be cool and clean, and there’s plenty of room to swim, float, or skip rocks. 

It’s a popular spot on sunny weekends, so arrive early to get parking ($5 day-use fee). There are restrooms, trails, and even a disc golf course if you need a break from the water.

5. Sauvie Island Beaches – Columbia River

Sauvie Island is known for its u-pick farms and birdwatching, but its long stretches of beach along the Columbia River also offer great spots for a summer swim. Walton Beach is one of the most popular places to swim, sunbathe, and picnic, located approximately nine miles from the Sauvie Island Bridge. 

The river current can be strong in some areas, so stick to calmer sections and always swim with caution. A day-use parking permit is required, which can be purchased at island stores or online. Arrive early on hot weekends—parking may fill up fast.

6. Henry Hagg Lake – Gaston

About an hour southwest of Portland, Hagg Lake is a warm-water reservoir in a scenic setting. There are two main designated swim areas—C-Ramp Recreation Area and Elks Picnic Area—offering shoreline access, picnic shelters, and restrooms. The lake is also popular for kayaking, paddleboarding, and boating, and the surrounding park includes trails and viewpoints. It can get breezy in the afternoon, so mornings are ideal for a quiet swim.

7. Wilson River – Tillamook State Forest

The Wilson River winds through the Tillamook State Forest and is home to several excellent swimming holes, including the ever-popular Footbridge Trailhead and Jones Creek areas. About 90 minutes from Portland, the Wilson offers clear, cool water in a forested canyon with deep pools perfect for a refreshing plunge. These spots are also suitable for fishing and hiking, which allows you to make a full day of it. The river is chilly even in summer, but the peaceful setting more than makes up for it.

8. North Santiam County Park – Stayton

Tucked along the North Santiam River just outside of Stayton, North Santiam County Park is a quieter, less-crowded alternative for river swimming about 75 minutes south of Portland. The park boasts a peaceful atmosphere, featuring shaded picnic tables, restrooms, and ample shoreline access to the cool, clear river. Swimmers can enjoy shallow areas for wading or deeper spots for floating and swimming. It’s also a popular spot to launch a tube or kayak, especially on warm weekends.

Because it’s a bit farther from the metro area, it often flies under the radar, making it an excellent pick for those looking to escape the city crowds. Just make sure to bring everything you need, as there are no concessions on-site.

Swimming Smart in Natural Waters:

• Check water conditions, weather, and current updates before heading out.
  
• Swim only in designated or commonly used spots—avoid areas with unclear access.
  
• Bring water, sunscreen, snacks, and shade.
  
• Always pack out what you pack in. Respect nature and other swimmers.
