Barra do Superagui to Praia Deserta
A good first outing is to use the established approach from Barra do Superagui, spend time on the beach and return without committing to a long coastal traverse. ICMBio describes about 40 minutes for the approach. Treat that as a published estimate, not a promise for your group. Ask locally which return is suitable at the day’s tide; do not turn an alternative beach return into an assumed all-tide loop. Pause to notice vegetation changes, but keep to the route rather than stepping into dunes for a better photograph.
