Enjoy a hike in the beautiful Sitka Spruce Temperate Rainforest. The South Slough Trail is south of the Fort to Sea Trail and can be combined with the Fort to Sea and Kwis Kwis trails for a longer hike. The South Slough Trail includes a boardwalk over a wetand restoration area.

The South Slough 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 and sections of the trail that can be slick and muddy.

Know before you go what the weather will be like, where you are going. There is a bathroom at Netul Landing and one at the Fort to Sea Trailhead. There are no water fountains, so make sure you bring plenty of water and snacks. Please also plan on packing out anything you pack in as there are no trash cans along the trail.
