Gorriti Island, a pristine natural reserve off Punta del Este, Uruguay, offers a serene half to full-day excursion, easily accessible by a short, inexpensive ferry ride from the city's port. While visitors can explore solo, guided tours are available for deeper insights into its history, including 18th-century fortifications. The island is best visited during the peak summer season (December-March) for ideal beach conditions, though ferries operate year-round, potentially with reduced services off-season. Costs are primarily limited to the ferry fare (typically around $10-15 USD round trip), as there are no entrance fees. Visitors should plan for 3-6 hours to enjoy its beautiful beaches like Playa Honda, explore historical ruins, and walk nature trails, and are advised to bring their own food, water, and sunscreen as facilities are minimal.
