The most heavily traveled branch of this trail ends at DuPont Beach, a classically "Alaska-style" beach made of gravel and small rocks. Although there isn't warm sand to dig your toes into, you can enjoy beautiful views across the water, and this is still a good place for a picnic.
Some people do hike back into the forest and look for an intersection that will take them farther east, then southeast, toward Point Bishop — another gravelly section of coast. However, this section of trail tends to be even more overgrown, muddy, and eroded than the trail you walked to reach DuPont Beach.
There is good saltwater fishing for Dolly Varden off DuPont Beach in the spring. If you decide to fish, you will need a sportfishing license and information about local regulations. adfg.alaska.gov/index.cfm?adfg=fishregulations.se_sportfish
