Boardwalks and trails through the island's tidal wetlands

Port Aransas Nature Preserve at Charlie's Pasture

A free city nature preserve of boardwalks and trails through tidal flats and wetlands — Port A's best easy-access birding.

The wild wetland behind the beach town

The Port Aransas Nature Preserve at Charlie's Pasture protects a broad stretch of tidal flats, salt marsh and wetland between the town and the ship channel. A network of trails and elevated boardwalks lets you walk straight out into it without getting your feet wet — and it is completely free.

Come for the birds

This is one of the most rewarding birding spots on the island. Herons, egrets, roseate spoonbills, shorebirds and migrating songbirds all work the flats, and the boardwalk's height gives you clean sight lines. It is flat, easy walking, good for kids and casual visitors as well as serious birders. Bring water, sun protection and bug spray — there is little shade and the marsh has mosquitoes when the wind drops.
