Alder Flat Hiking

The hike to Alder Flat is scenic and easy. The one-mile, well-maintained trail winds through a lush forest of towering firs, cedars, and red alder trees, making it great for a peaceful nature walk.

Along the way, hikers can enjoy the sights and sounds of the forest, with opportunities to spot various local wildlife and seasonal wildflowers. The trail leads directly to the river, where visitors can relax, swim, or camp in the serene surroundings.

Alder Flat Swimming

The swimming hole is absolutely breathtaking. Its crystal-clear turquoise waters, paired with a sandy and rocky beach, create the perfect spot for relaxation. A midstream rock formation serves as a popular spot for jumping, adding an adventurous element to your visit.

The pool is deep, and the current is relatively slow along the river's bend during low water levels. Be sure you have moderate or advanced swim skills for safe swimming in the Clackamas River.

However, caution is advised during periods of high water flow when the river’s current becomes faster and more dangerous. Be mindful of rapids located both upstream and downstream from the swimming area.

Upper Clackamas River Fishing

Anglers can catch cutthroat trout, rainbow trout, bull trout, Chinook salmon, coho salmon, and winter and summer steelhead. All native trout, salmon, and steelhead smolts must be released.

However, anglers may keep up to five hatchery trout daily, provided they are 8 inches or longer and have their adipose fin clipped. Bull trout are a protected species and should always be handled with care and released unharmed.

There are six primitive campsites, each equipped with a picnic table and fire pit. Every campsite is nestled within a peaceful grove of red alder trees, offering privacy and shade. The campground is open year-round.
