Pico Cão Grande: The needle-shaped volcanic challenge of São Tomé island

Nestled on the lush island of São Tomé in the Gulf of Guinea, Pico Cão Grande is not just a geological marvel but also an extreme challenge for the world’s most daring climbers. Towering nearly 400 meters tall, this needle-shaped volcanic spire rises dramatically from the rainforest, a mystical symbol of the island’s natural power and volcanic past.

The Mystery of the “Great Dog Peak”

Pico Cão Grande—meaning “Great Dog Peak” in Portuguese—is a volcanic plug formed from solidified magma after volcanic eruptions ceased. Over time, erosion gradually exposed this sheer rock formation, now standing as a formidable natural tower.

Its uniqueness lies not only in its striking shape but also in the mist that frequently shrouds it, giving it an aura of mystery. From afar, Pico Cão Grande resembles a tower from a fairytale kingdom. In reality, it is one of the most challenging climbing destinations in the world.

An Extreme Challenge for Climbers

Not everyone is equipped to conquer this spire. Its nearly vertical walls offer little to no handholds, and the thick moss and high humidity turn every step into a battle against gravity. Add to this the unpredictable equatorial weather and sudden downpours, and the dangers multiply.

Rising nearly 400 metres above the island’s rainforest, this tower-like structure, shrouded in mist and often shrouded in clouds, is considered one of the most challenging climbs in Africa.
  • The First Ascent: In 1991, a Japanese climbing team achieved the first successful ascent, paving the way for future adventurers.
  • Recent Milestones: In 2016, Gareth Leah and Sergio Almada established the Nubivagant (“climbing into the clouds”) route, a technically demanding climb rated F8b. Two years later, the Pou brothers from Spain made history by conquering the route without climbing aids—a monumental achievement in the climbing world.

Beyond the challenging terrain, climbers must also contend with local wildlife. The black mamba, one of the world’s most venomous snakes, is an unwelcome companion for the brave explorers on this island.

Pico Cão Grande is not for the faint of heart. This is a climb reserved for experienced climbers with a sense of adventure and respect for the power of the mountain.

A Destination for Adventurous Souls

Whether you are a seasoned climber or simply a nature enthusiast, Pico Cão Grande offers a one-of-a-kind experience found nowhere else in the world. Conquering this needle-shaped volcanic spire is not just a physical feat but a journey into the depths of self-discovery.

When you leave the summit, you’ll carry more than just awe-inspiring photos; you’ll leave with a sense of triumph and profound respect for the enduring power of nature.
