Mljet National Park, located on Mljet Island in Croatia, is a highly accessible natural gem, reachable by ferry services from various mainland and island ports, with well-maintained paths and electric transport within the park. It can be easily explored solo for hiking, cycling, and swimming, though guided tours are available for those seeking deeper insights into its rich biodiversity and cultural heritage. The park is open year-round, but the main tourist season from May to October offers the best services and most frequent transport, while off-season visits provide a tranquil experience with limited facilities. An approximate cost includes the park entrance fee (typically €10-€25, often with a boat trip to St. Mary's Islet), separate ferry tickets to the island, and optional bike rentals. A typical visit duration is a full day (6-8 hours) to fully appreciate the saltwater lakes (Veliko and Malo Jezero), the Benedictine monastery on St. Mary's Islet, and enjoy activities like swimming, kayaking, or hiking through the lush Mediterranean forest. Visitors should bring comfortable shoes, swimwear, and sun protection to fully enjoy this pristine natural environment.
