At Ilha Anchieta, the change of pace begins with the crossing. The mainland recedes, forested slopes come into view, and a beach visit becomes something more layered. The 828-hectare state park protects an island landscape with seven beaches, rocky shores, dense Atlantic Forest and restinga, the coastal vegetation associated with sandy ground. Those environments are close together, but they are not interchangeable: notice how exposure, shade and vegetation change as you move away from the waterfront.
Start with the visitor centre and the historic area before choosing how far to walk. The prison remains can look picturesque from a distance, yet this was a place of confinement and violence, not a decorative ruin. A penal colony opened here in 1908; the island later held political prisoners, and a major uprising occurred in 1952. The prison closed in 1955, while the state park was created in 1977. Read the interpretation with that change of purpose in mind.
The wildlife story is equally worth slowing down for. Many familiar-looking mammals were deliberately released on the island in 1983. They are introduced to this island even where the same animals are native elsewhere in Brazil. UNESP researchers have documented black-tufted marmosets and agoutis, among other mammals, and studied how their populations affect the ecosystem. Seeing an animal running freely does not, by itself, mean that it belongs to the island’s original fauna.
For a first visit, choose either a gentle history-and-restinga outing or one monitored forest trail. Leave unallocated time for a drink, changing clothes, a conversation with a monitor or simply watching the shore. The practical limit is often your boat’s time ashore, not your appetite for walking. A short sightseeing stop and a full island day are different products; establish which one you are buying before making plans.
