The breezy shores of Delnor-Wiggins State Park, 12 miles north of Naples, entice thousands of beachgoers on summer days . The Observation Tower Trail at Delnor-Wiggins is a 0.3-mile boardwalk through a tangled coastal tropical forest. Start near the picnic pavilion, then take the boardwalk, which winds its way through the dense woods. It leads you to a tower from which you get a sweeping view of Wiggins Pass and the Gulf of Mexico, with lots of mangroves way down below. The entire trail is 0.8 miles one way.
To add some distance: you can continue the full length of the beach up to the south end of the park and back, which will add 2 more miles to your exploration of this shoreline.
