Amazon & Natural Wonders

★★★ Leticia — The Gateway to the Amazon

Leticia is Colombia's southernmost point and the capital of the vast Amazon Department (109,665 km², almost uninhabited). The city lies directly on the Amazon River at the tri-border area with Brazil (Tabatinga, directly adjacent — you can walk across the border!) and Peru (Santa Rosa, accessible by boat). It is one of the few places in the world where three countries blend seamlessly.

The city itself has about 50,000 inhabitants and serves as a base for jungle adventures. Typical activities include:

• Jungle Lodges: 2–4 nights in a lodge by the river, surrounded by rainforest. Program: jungle hikes (day and night!), canoeing through flooded forests, piranha fishing, searching for caimans at night, visiting indigenous Ticuna communities.
• Pink River Dolphins: The Amazon dolphin (Boto) is the largest freshwater dolphin in the world — and indeed pink. Best seen in the rainy season (Apr–Jun) and in the Lagos de Tarapoto.
• Isla de los Micos (Monkey Island): An island full of squirrel monkeys that climb onto your shoulders. Touristy, but fun. 50,000 COP (12€) by boat.
• Tri-border Area: By boat to the point where Colombia, Brazil, and Peru meet. In the evening, head to Tabatinga (Brazil) for a Caipirinha and Brazilian Churrasco — bring your passport!

Practical Info

Getting there: Only by plane. Avianca and LATAM fly from Bogotá (2h, 200,000–500,000 COP / 50–120€ one-way). No road connects Leticia with the rest of Colombia.

Climate: Tropical-humid. 25–35°C, high humidity year-round. Drier months: July–September (less rain, river levels drop, beaches become visible). Rainy season: April–June (highest water levels, jungle "underwater" — perfect for canoeing).

Budget: Jungle lodge all-inclusive: 200,000–450,000 COP (50–110€) per person/night including tours and meals. Cheaper option: day tours from Leticia (100,000–150,000 COP / 25–35€).

What to bring: DEET mosquito repellent (a must!), long clothing, rain gear, rubber boots (often provided), flashlight, travel pharmacy with malaria tablets (consult a tropical doctor). Malaria risk is low but present.

★★★ Caño Cristales — The Most Beautiful River in the World

Caño Cristales is often referred to as the "River of Five Colors" or the "Rainbow River" — and when you see it, you'll understand why. Between June and November, this river in the Serranía de la Macarena transforms into a psychedelic natural spectacle: Red, yellow, green, blue, and black shine from the crystal-clear water.

The colors come from Macarenia clavígera, an aquatic plant growing on the riverbed that changes color between the rainy and dry seasons. With optimal water levels (not too high, not too low) and sunlight, the incredible color spectacle emerges.

Practical Info

• Season: Accessible only June to November. In the dry season (Dec–May), the river is closed, and the plants regenerate. Peak: September to November (most intense colors).
• Getting there: Flight from Bogotá to La Macarena (1.5h, Satena or EasyFly, 250,000–400,000 COP / 60–95€ one-way). No road!
• Tours: Visits are only possible with a licensed guide. 2–3 day packages from 600,000–1,200,000 COP (140–280€) including flight, guide, accommodation, meals. Book through agencies in Bogotá or La Macarena.
• Rules: No sunscreen in the water (damages the plants), no shoes in the river, only on marked paths. The rules are strictly enforced — and that's a good thing.

The visit is logistically a bit demanding, but absolutely unique. There is no other place like this on Earth.

★★ Desierto de la Tatacoa

The Tatacoa Desert is not a true desert but a tropical dry forest — yet the surreal landscape of ochre and gray rock formations, cacti, and deep erosion gorges feels like landing on Mars. Spanning 330 km², it consists of two areas:

• El Cuzco (red zone): Spectacular orange-red rock labyrinths shaped by wind and water over millennia. Hikes through narrow gorges, photogenic formations, surreal light at sunrise and sunset.
• Los Hoyos (gray zone): Gray-white rock landscape reminiscent of a lunar surface. Less visited but equally impressive.

★★★ Starry Sky

The Tatacoa Desert offers the clearest starry sky in Colombia. Far from any major city, with extremely low light pollution, the night sky here is overwhelming. An observatory (Observatorio Astronómico de la Tatacoa) offers telescope observations (20,000 COP / 5€, from 19:00) — Milky Way, Saturn's rings, and nebulae with the naked eye and through the telescope.

Practical Info

The Tatacoa is located near the town of Villavieja, 45 km north of Neiva (Department Huila). Getting there: Bus Bogotá → Neiva (5–6h, 40,000 COP / 10€), then Collectivo to Villavieja (30 min, 5,000 COP). In the desert, there are simple accommodations (hostels, campsites, from 30,000 COP / 7€) and a few restaurants.

The best time to visit: Dry season (Jun–Sep and Dec–Feb). Heat is extreme (up to 42°C!) — hikes early in the morning or late afternoon, spend midday heat in the pool. Stay at least one night for the starry sky.
