About Alder Flat
Alder Flat is a peaceful, primitive hot spring nestled along the upper Clackamas River in Oregon. This rustic spot offers a refreshing swimming hole rather than a traditional hot soak, with its cool, flowing waters creating a serene getaway from city life. Its untouched natural vibe invites you to connect directly with the forest and river surroundings.
Getting There
Reach Alder Flat by driving 26 miles east from Estacada on Route 224, parking near the trailhead with limited spots available. The spring is an easy 18-minute walk through shaded forest, leading to a quiet campground and the river’s edge. The access trail is straightforward, making it accessible yet tranquil.
What to Expect
The swimming hole features cool, brisk water year-round with a steady current, offering a refreshing dip on hot summer days. The riverbank is serene and rarely crowded, providing a peaceful atmosphere without facilities—no restrooms or running water—so you experience nature in its purest form. Bathing suits are optional here, enhancing the sense of freedom.
Tips for Visitors
Visit Alder Flat in summer for the most comfortable swimming conditions and peaceful surroundings. Bring all necessary supplies, including water and waste bags, as the site has no amenities. Respect the natural environment by packing out everything you bring in, and use caution in the river’s current for safe swimming.
