Start Fort to Sea Trail

While the Corps forged its way through deep woods, muddy bogs and windswept beaches, a 6.5-mile trail now runs through much of the same forest, fields and dunes that the Corps traveled. The Fort To Sea Trail starts in the woods south of Fort Clatsop and goes to Sunset Beach on the Pacific Ocean, winding through ancestral lands of the Clatsop Indians who aided the Corps during their 1805/1806 winter stay at the Pacific.
The Fort to Sea trail makes a great day hike if you have prepared well. There are sections of the trail that are steep, going both uphill and downhill, sections of the trail that can be slick and muddy, and areas without much vegetative cover. Know before you go what the weather will be like, where you are going, and how you will get back to your car (remember it is 6.5 miles ONE WAY ). There are bathrooms at the trail head, sunset beach, and about halfway through. There are no water fountains so make sure you bring plenty of water and snacks.
