Remote beautiful location in the Mount Hood National Forest
Deep emerald swimming holes on the bend of the Clackamas River
Basalt outcroppings and rocky beaches
If your aim this summer is to beat the crowds and enjoy the great outdoors then Alder Flat at the Mount Hood National Forest is one of the best place to go.
This place is an hour drive of Portland. The only way to access the backcountry campsites and the swimming hole is via approximately mile-long hike along the Alder Flat Trail. Adventure enthusiasts might find the trail too short and easy. However, the journey is quite rewarding in itself and the destination is definitely worthwhile.
It is due to this very 1-mile walk to reach the pool and basalt outcroppings that Adler Flat is far less populated than all other swimming holes along the Clackamas River.
The destination for all those who jump onto Alder Flat trail is the cool rocky beach that forms the front of the swimming hole at Alder flats, or one of the five primitive campsites that overlook the river. Every campsite near Alder Flat is completely enclosed by a grove of red alder that gives this swimming hole its name.
Originating from the Dry Creek Pond, the trail meanders through a variety of species of rushes, ferns and skunk cabbage. Adventure enthusiasts can also try their hand at fishing in the wild and scenic Clackamas River and attempt to capture trout or salmon.
No restroom, no drinking water, no garbage service on the site. Leave the land better than you find it – pick up all trash you find and take it with you.
