Backpacking in Pico Biao
🏆 Top pickhike ranked #1
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

Pico Biao sits inside the Gran Caldera and Southern Highlands Scientific Reserve, where the roads are few and no marked trail is maintained for visitors, so a local guide is a practical necessity. The peak stands in the south of Bioko island in Equatorial Guinea, reached from the highland side near Moka. Expect steep, muddy ascents through montane forest, frequent cloud and rain, and a climb of roughly 1,000 meters over a short distance. It is a demanding two-day outing, not a casual walk. The scenery is dense green forest, mossy ridgelines and the odd opening onto the volcanic landscape. Wildlife is the draw, with endemic primates and many forest birds. Getting to the start by public transport means a shared taxi to Moka from the capital, then a walk or local lift, and the rest is on foot. Compared with Pico Basilé, which has a road almost to the top and an antenna station, Pico Biao is wilder, quieter and far less visited.

✨ Why go?
Ranked #1 hike in Equatorial GuineaWhy visitors keep coming back

Pico Biao attracts the backpackers who have already done the easy summit on Bioko and want a version with no road, no crowds and real forest. The first reason is the setting: the climb passes through some of the least disturbed montane forest on Bioko, a habitat that holds several species found nowhere on the African mainland. Walking quietly with a guide, you have a fair chance of hearing drills, guenons or colobus long before you see them. The second is access from the highland village of Moka, which keeps the start reachable on shared transport and a short walk, without a private expedition. The cool air at altitude is its own appeal after the coastal heat of Malabo. The third is the flexibility: you can turn back at a ridge viewpoint, camp for a night, or push on to the summit depending … read more 👉

The cool air at altitude is its own appeal after the coastal heat of Malabo. The third is the flexibility: you can turn back at a ridge viewpoint, camp for a night, or push on to the summit depending on weather and legs. It also fits neatly into a longer island loop that takes in the crater lakes and the beaches of the south.

💡 HighlightsPlaces and moments you shouldn't skip

  1. Pico Biao summit: The peak itself is the objective, a volcanic high point in the southern highlands. On clear mornings the view runs over unbroken forest toward the caldera rim, but cloud often closes in by midday, so an early start matters.
  2. Moka cloud forest: The forest above Moka is cool, wet and thick with moss, ferns and epiphytes. Trunks are draped in green, and the temperature drop compared with the coast is noticeable within the first hour of walking.
  3. Lake Loreto (Laguna Loreto): This crater lake near Moka makes a calm side stop before or after the climb. The water sits in a forested bowl, and the quiet is broken mostly by birds and frogs.
  4. Gran Caldera de Luba rim: The huge collapsed volcanic basin lies close to the Pico Biao area, and ridge sections give a sense of its scale. It is one

  4. Gran Caldera de Luba rim: The huge collapsed volcanic basin lies close to the Pico Biao area, and ridge sections give a sense of its scale. It is one of the most remote landscapes on Bioko, with very little trace of settlement.
  5. Bioko primates: The island is home to drills, Preuss’s guenons and Pennant’s red colobus, each a subspecies or species found on Bioko. Sightings are never guaranteed, but listening for crashing branches and calls in the early hours is the best strategy.
Start with the Moka cloud forest and Lake Loreto, since a short walk there shows you how the weather and terrain behave before you commit to the full climb.

🌤️ When to go?When to go for the best experience

  • Dry Season (December to February): Pico Biao on Bioko Island is easiest to climb now, with the clearest trail and the best odds of summit views. Expect 22 to 30°C (72 to 86°F) in the lowlands and roughly 8 to 14°C (46 to 57°F) near the top at night. Dust haze from the Harmattan can blur distant views.
  • Transition Months (March to May): Showers build through the afternoons, and cloud settles on the ridge by midday. Start at first light. Daytime temperatures hold at 24 to 30°C (75 to 86°F).
  • Wet Season (June to October): Rain falls most days and the peak sits in cloud almost constantly. The trail turns to slick mud, and the temperature drops to 10 to 16°C (50 to 61°F) on the upper slopes. Views are rare.
  • Late Wet Season (November): Rains ease, and the trail begins to firm up.

Daylight stays close to twelve hours all year, so plan on finishing by mid-afternoon. Crowds are minimal in every month, and transport and guide prices barely change. Book a mid-week start in January for the clearest odds.

🥾 Hike detailsRoute, distance, and difficulty explained

Total Distance: Pico Biao is roughly 20 kilometers return from the highland start, depending on the route your guide takes.
Estimated Duration: Plan on two days, with a night camping or in a basic shelter, or a very long single day for strong hikers.
Difficulty: Demanding. Trails are faint, slippery and often unmarked, and navigation needs a local guide.
Starting Point: The walk begins in the highlands near Moka.

Starting Point: The walk begins in the highlands near Moka.
  • Public Transport: Shared taxis run from Malabo toward Moka, a long ride by road, and the last stretch is usually covered on foot or by a local lift.
  • Permission: The area lies in a protected reserve, so arrange access and a guide beforehand.
Major Landmarks:
  • Moka: A cool highland village and the usual staging point.
  • Lake Loreto: A crater lake close to the start.
  • Ridge viewpoints: Occasional breaks in the canopy with views toward the caldera.
  • Summit: A forested volcanic peak with limited views when cloudy.
Terrain and Scenery: Steep, root-tangled slopes, mud, stream crossings and volcanic soils. The ridge sections open briefly onto sweeping green landscapes.
Vegetation: Montane forest with tree ferns, moss, orchids and giant buttressed trees, giving way to lower, more stunted growth near the top.
Wildlife: Drills, guenons and red colobus monkeys, plus forest birds, frogs and many insects. Leeches and biting ants are common underfoot.
Practical Notes: Bring waterproofs, boots with real grip, a water filter and warm layers for the night, as the highlands are cool and damp.
⚠️ Hiking info can sometimes be outdated or inaccurate. Before you hit the trail, check the latest conditions with locals. If you do spot anything that's off, I'd love to hear from you, so I can update it for fellow travelers.

🛡️ SafetyScams, Hazards, and Annoyances

Pico Biao is a steady but unforgiving climb, and the main hazards are weather and fitness rather than wildlife. Cloud and rain arrive fast above the forest line, dropping temperatures sharply, so carry a waterproof shell and a warm layer even if the base is hot. The trail is steep, rooted and muddy, and footing slips most on the descent, so wear boots with real grip and use poles if you have them. Navigation through the forest and cloud is confusing, so go with a local guide who knows the route. Pace yourself on the way up, drink regularly, and carry more water than seems necessary because humidity drains you. Start early to finish in daylight. Bioko’s primates, including drills, are hunted in places and wary, so give any animals you meet distance and never feed them. Tell someone your plan … read more 👉

FAQFrequently asked questions about Pico Biao

Pico Biao takes most hikers two days: a long ascent to the summit area followed by a descent, typically 6 to 9 hours up and 4 to 6 hours down. Many groups camp or overnight near the upper slopes to catch clearer morning views. Fast, fit hikers sometimes manage a very long single-day push from the Moka or Malabo side, but a two-day plan is safer.
Pico Biao is a moderate to hard hike, mainly because of the steep gradient, muddy footing and a summit around 3,010 meters (9,875 feet). Total climbing is substantial, and cold, wet weather near the top adds to the effort. Good fitness, sturdy boots and rain gear are needed, though no technical climbing skills are required.
Pico Biao is best done with a local guide, and hiring one is strongly advised because the trail through forest and cloud is hard to follow. Guides are usually arranged in Malabo or through tour operators, with costs typically around €40 to 100 per group depending on days and transport. Check current permit requirements for the Pico Basilé area with local authorities or your operator before you go, as arrangements can change.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackWhat to keep in mind

Pico Biao suits patient, self-sufficient hikers who care more about forest and wildlife than a tidy summit photo. Hire a guide who knows the ridges, pack for rain regardless of the forecast, and start at first light. If you only want a view, take the easier road to another peak on Bioko and save this one for another trip.
