São Tomé Island

São Tomé Island is the larger and more populous of the two islands, acting as the cultural and economic hub of the nation. For families, it offers a diverse range of activities that span from mountain trekking to cultural immersion, all within manageable driving distances. The island is dominated by the imposing Obo National Park in the center, home to the needle-like volcanic plug Pico Cão Grande, which looks like a fantasy tower rising out of the jungle. While the peak is for serious climbers, the view from the road is a spectacular photo opportunity that fascinates children.

The coastline is the main playground for visitors. In the north, the landscape is drier with baobab trees and blue waters. Lagoa Azul (Blue Lagoon) is a must-visit for families; the water is calm, shallow, and protected by rocks, effectively creating a giant natural swimming pool where kids can spot colorful fish with basic snorkel gear. Further down the coast, the Boca de Inferno (Hell's Mouth) offers a dramatic lesson in geology as waves crash through a natural rock arch, creating a booming geyser effect—best viewed from the safe viewing platform.

One of São Tomé's biggest draws for families is its chocolate culture. The island was once the world's largest cocoa producer, and many historic roças (plantations) are open to visitors. Tours at places like Roça Agostinho Neto or the Claudio Corallo factory in the capital allow children to taste the fruit of the cocoa pod (which tastes like tropical sherbet) before seeing how it transforms into chocolate. It is an educational and delicious experience that connects food to its source.

Traveling south brings you to lush, dense greenery and the boat crossing to Ilhéu das Rolas, a tiny islet located exactly on the Equator. Kids love the novelty of standing with one foot in the Northern Hemisphere and one in the Southern Hemisphere at the monument there. The islet also offers a resort environment with pool facilities if a break from exploring is needed.

The capital city, São Tomé, is a faded colonial gem with a bustling market and the historic São Sebastião Fort, now a museum. It is generally safe to walk around during the day, though standard travel vigilance is advised. The roads on the island vary in quality; renting a 4x4 is recommended for family road trips to handle potholes and steeper gradients comfortably. Food is a highlight here, with the national dish Calulu (a fish or meat stew with herbs) being widely available, alongside plenty of fresh grilled fish and tropical fruits like mango, papaya, and safe-to-eat bananas that sustain energy for long days of exploration.
