South Beach Trail

in Washington · centroid 67 mi from Seattle

The South Beach Trail is a 1.0 mile trail that traverses the American Camp prairie, connecting the Parade Grounds and South Beach at American Camp. The trail begins just after the historic structures at American Camp, heading straight and on level ground directly below The Redoubt. The trail slopes gently as you walk down towards South Beach at the trail's end.

To the east, the trail provides fabulous views of the North Cascades dominated by Mount Baker, the waters of Griffin Bay, Lopez Island, and the vibrant coastal prairie, where foxes, rabbits, voles, snakes, and eagles can be found. To the west, visitors can take in the waters of the Salish Sea and view the Olympic Peninsula a mere 13 miles away. This hike can be combined with the Coastal Bluffs Trail for an easy 2.0 mile loop trail which gives visitors access to the beaches at Grandma's Cove and South Beach.

It can be wet and slippery during the winter, so plan accordingly to stay safe.

Practical notes

Maps + permits: long-distance trails like this often require permits for through-hiking, backcountry camping, or specific sections (especially in National Parks). Check with the maintaining organisation listed above and the relevant land manager before booking travel.

Water + supplies: water sources vary seasonally on most U.S. trails. Carry a filter and consult current trail-condition reports — through-hiker journals (PCT-L, AT Reddit, etc.) and the maintaining organisation publish regular updates.

When to go: hiking seasons vary widely with elevation, latitude, and snowpack. Through-hikers traditionally start the AT in March-April (Springer northbound) and the PCT in late April (Campo northbound). High-elevation western trails (CDT, JMT, Wonderland) generally aren't passable until July.
