Rio Lembá is the most significant and one of the longest rivers in the west of São Tomé Island, flowing through the Lembá district named after it. It originates in the water-rich heights of the central volcanic massif at about 700 meters above sea level and drains large parts of the western highlands. Its course is characterized by deep, V-shaped valleys and spectacular gorges that bear witness to the enormous erosive power of water on the basaltic rock. During the colonial period, the Rio Lembá valley was an important center for agriculture, with the water used to irrigate extensive cocoa and coffee crops. The riparian vegetation consists of dense tropical forest, which represents an important corridor for the island's endemic fauna. The river eventually empties into the Bay of Lembá in the Atlantic, carrying significant volumes of water during rainy months. Today, the region around the river is largely sparsely populated due to its rugged topography, which has contributed to the preservation of natural water quality.

📋 Practical info
Getting there
Access to the river is usually best from the western coastal road of São Tomé, near the town of Neves. From the main coastal route, secondary dirt roads generally lead inland towards the river.
Best season
The most favorable time for a visit is generally during the dry season, locally known as Gravana, which runs from June to September. During this time, the river's flow is less extreme and safer.
Terrain & paths
The terrain along the river is characterized by steep valleys, rocky embankments, and dense tropical vegetation. Hiking here is generally challenging and involves navigating uneven, unpaved trails.
What to bring
Visitors should bring durable walking shoes with excellent grip to safely handle the rocky riverbanks. A lightweight rain jacket, sun protection, and a basic first-aid kit are highly recommended.
Parking
Vehicles are usually parked in the nearest accessible villages or along wider sections of the coastal road. Secure parking lots are rare, so it is advisable to ask locals for safe spots.
Safety
The river's untamed power means water levels can rise rapidly following heavy inland rains. Swimming is generally not recommended unless accompanied by a knowledgeable local guide.
Time needed
Exploring the accessible lower sections of the river typically requires about two to three hours. Those aiming to hike further upstream into the valleys should plan for a challenging half-day adventure.
