You'll have to pay close attention to spot the small trailhead sign that leads you onto the DuPont Trail instead of down a private lane.
Once you're on the trail, watch out for exposed roots and rocks, and general trail erosion, as you work your way through Jurassic-Park-style vegetation toward DuPont Beach.
Expect to spend quite a bit of time walking on boardwalks and plank bridges that help cover some of the irregularities in the forest floor. This can be fun, like an adult jungle gym, on dry days — or a slippery mess on wet days.
