You step off the boat at Vila do Abraão and the island swallows the mainland noise—salt air, insects tuning like radio static, and a narrow street that leads into the green throat of the Atlantic Forest. Over four days the trail pulls you along ridge lines, through leaf litter and through small fishing villages where time is measured by generator hours and tide.
