Backpacking in Lagoa Azul
👌 Worth visitingunique site ranked #4
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

Lagoa Azul is a salt-water bay on the open Atlantic, so the blue comes from sea and sky rather than a lagoon. You find it on the northwest coast of São Tomé island in São Tomé and Príncipe, north of the capital. The access road is rough, and you feel every pothole before the trees open onto black volcanic rock and a pocket of water that turns from bottle green to deep turquoise over sand. Step in and the cool shock gives way to clear water, with small fish nosing around your ankles. Crowds stay thin, shade is limited, and facilities are basic, so you bring your own snacks. Fishermen haul wooden canoes up the shore, and the smell of salt and wood smoke drifts over the sand. Compared with nearby Praia das Conchas, which is about rock pools and photos, Lagoa Azul suits snorkeling and lingering.

✨ Why go?
Ranked #4 unique site in São Tomé and PríncipeWhat makes it a must-see unique site

Lagoa Azul gives you a proper swim and snorkel within easy reach of the capital, without a multi-day expedition. The bay is sheltered enough that you can drift over the clear turquoise shallows and watch reef fish dart between the dark lava rocks, which is hard to match on the busier beaches near town. It also fits a loop through the north of the island. Pair it with the old cocoa estates, the coastal fishing villages and the Praia das Conchas rock formations, and you have a full day that costs little and needs no guide. The atmosphere stays local: kids splash beside moored canoes, and nobody pushes tours on you. If your route is heavy on cities and cultural stops, a few hours here resets the pace and gives you the sort of quiet that small islands do best. Bring a mask, because the water clarity is the main attraction.

💡 HighlightsDon't-miss highlights and experiences

  1. The turquoise bay itself: a sheltered cove where the water shifts from green to deep blue over pale sand, framed by palms and dark volcanic rock.
  2. Snorkeling the rocky edges: the lava outcrops hold small reef fish and are the best spot to get underwater with a mask.
  3. Fishing canoes on the shore: wooden dugouts are pulled up on the sand, and local fishermen mending nets make for honest, unposed photos.
  4. The palm-fringed beach: a short stretch of sand with patchy shade, good for a long lunch and a nap after a swim.
  5. Volcanic rock shoreline: black basalt shapes contrast with the bright water, and the pools between them are fun to explore at low tide.
  6. The forest approach: the track in passes dense green vegetation and a few small houses, so the drive is part of the day.

For a first visit, start with the turquoise bay itself, because the swim and the snorkel there are the whole point of coming.

🌤️ When to go?Best time to visit Lagoa Azul

  • Gravana (dry season, June to September): Lagoa Azul is easiest to reach and clearest for swimming now. Days run 24 to 29°C (75 to 84°F), nights drop to about 20°C (68°F), and the sky is often overcast and breezy. Seas are choppier, so boat trips from the north can be rough.
  • Short dry spell (January to February): Rain eases and the water is calm, with sunnier skies than in the main wet months. Temperatures sit around 25 to 31°C (77 to 88°F). This is my pick for sunshine and clear water together.
  • Wet season (October to May, peaking March to April): Heavy downpours turn the dirt tracks to mud and the bay can cloud with runoff. It is hot and sticky at 26 to 31°C (79 to 88°F). Few people visit, and rooms are easy to book.
  • Daylight and crowds: Day length barely changes, so plan on roughly 12 hours

Go early in the morning, when the water is stillest and the light is best for photos.

🛏️ Where to stay?Where staying makes the most sense

The best base for Lagoa Azul is the north coast around Santana and Guadalupe, with the capital, São Tomé city, as the social fallback. The lagoon sits on the northern coast, about 30 to 45 minutes by road from the capital, so you can stay in either place. Guadalupe is a quiet, safe town with a market, small eateries and shared taxis heading north. It suits travelers who want a local feel and don’t mind early nights. Santana, a bit further along, has a handful of simple guesthouses and is closer to the coast, though evenings are very quiet and you will mostly meet other guests over dinner. São … read more 👉

Guadalupe is a quiet, safe town with a market, small eateries and shared taxis heading north. It suits travelers who want a local feel and don’t mind early nights. Santana, a bit further along, has a handful of simple guesthouses and is closer to the coast, though evenings are very quiet and you will mostly meet other guests over dinner. São Tomé city is where backpackers actually gather. The Praia Gamboa and city-center streets hold the most hostels and cheap guesthouses, plus cafés, bars and tour operators who can arrange rides to the lagoon and other sites on the island. Solo travelers will find it easiest to split taxi costs here. Walking around the center in daylight is generally comfortable. After dark, take a taxi rather than walking the unlit outskirts. Book ahead in July and August, when rooms fill up faster.

Wildlife is part of the experience. You might spot colorful birds or curious monkeys. Keep your distance and don’t feed them; they’re part of the ecosystem, not your hiking buddies.

Lagoa Azul needs about two to three hours on site for a swim, snorkel and picnic. Add the drive from São Tomé city, roughly 30 to 45 minutes each way, and a half day is plenty. If you pair it with nearby beaches and the north coast, plan a full day.

We 💚 feedbackIs it worth it?

Lagoa Azul looks best early, when the fishermen are bringing in the night’s catch and the water is flat and clear. Most first-timers stay on the sand and miss the lava rocks at the edge, where the best snorkeling is. I would bring a mask, water shoes for the rocks and snacks, then swim before the wind picks up.
