Just outside town, the state park's most popular hike is this 1km trail across the dunes to a cluster of beachside barracas (stalls selling beer and seafood). From Itaúnas, cross the bridge over the river and follow the dirt road until the dunes slope down to meet it. At the crest of the first dune, panoramic views of the ocean unfold.

Off to the right, the site of the original village of Itaúnas (now buried in sand) is clearly signposted.
