Ilhéu de Vila Franca is a stunning islet located off the coast of Vila Franca do Campo in the Azores, Portugal, formed by a volcanic crater. It's a popular destination for swimming, snorkeling, diving, and sunbathing within its natural volcanic pool. Accessibility is limited to boat trips from Vila Franca do Campo, which operate seasonally, typically from May to October, due to weather conditions. Solo visits are possible once on the islet, but transportation requires organized tours. The cost for a boat trip and access to the islet usually ranges from €10-€20. A typical visit lasts around 2-3 hours, allowing ample time to explore the crater and enjoy the water. Note that the islet has limited facilities, so visitors should bring their own food, drinks, and sun protection. The islet is a protected area, and visitor numbers are often limited to preserve its natural beauty, so booking in advance is highly recommended.
