Lagoa Azul is a small bay located on the north coast of São Tomé. This bay belongs to the Parque Natural Obô de São Tomé and is known as a great place for diving. Strange trees reminiscent of a baobab tree, a rocky shore, and the complete absence of crowds are a desirable change for a one-day visit. There is a lighthouse nearby with an amazing view, and local vendors exhibit their souvenirs nearby.
