Lagoa das Sete Cidades Reserve is a stunning volcanic caldera featuring twin lakes surrounded by lush forests, offering a unique blend of geology, biodiversity, and scenic recreation in the Azores archipelago.
Lagoa das Sete Cidades Reserve is located on São Miguel Island in the Azores and is anchored by two striking crater lakes—Lagoa Verde (Green Lake) and Lagoa Azul (Blue Lake)—nestled within a vast volcanic caldera. The area covers rugged volcanic terrain, verdant laurel forests, endemic plant species, and diverse birdlife, making it an ecological haven. The reserve is part of the larger Sete Cidades Natural Park, managed to conserve its delicate ecosystems and unique volcanic landscape. Visitors are drawn to spectacular panoramic viewpoints such as Vista do Rei, hiking trails that meander through azorean laurisilva forest and around the lakes, and opportunities for kayaking, birdwatching, and cycling. The area's geological history includes a massive volcanic eruption thousands of years ago, shaping the distinct twin lake formation symbolic of the Azores. Cultural heritage also enriches the experience, with local traditions and quaint nearby villages offering hospitality and insight into island life. As one of the most iconic sites in the archipelago, the reserve balances conservation and sustainable tourism, welcoming nature lovers and photographers seeking breathtaking landscapes and outdoor adventure. It offers a serene escape with mild, oceanic climate conditions year-round, amplifying its appeal for hiking, picnicking, and quiet reflection in the presence of extraordinary natural beauty.
