Rivers are the lifeblood of Guyana. In a country where roads end and rainforest begins, rivers become highways — carrying supplies to remote communities, providing food for villages, and offering visitors access to some of the most pristine wilderness in South America.
From the mighty Essequibo — the largest river between the Orinoco and Amazon — to the wildlife-rich creeks of the Rupununi, river tours in Guyana deliver unforgettable encounters with giant otters, black caimans, river dolphins, and countless bird species.
Major River Systems
The Essequibo River
The Essequibo is Guyana's greatest river, stretching 1,010 kilometers from its source in the southern mountains to the Atlantic. At its mouth, it's 20 kilometers wide — more an inland sea than a river. This is the main artery through the heart of Guyana's rainforest.
Essequibo River Tours
Tours on the Essequibo range from day trips near the coast to multi-day expeditions deep into the interior. The river passes through the Iwokrama Forest, offering access to some of Guyana's best wildlife areas. Boat trips from Iwokrama River Lodge are particularly rewarding.
Day trips from $80 USD | Multi-day included in lodge packages
The Demerara River
The Demerara flows past Georgetown and provides easier access for day trips from the capital. While more developed than the Essequibo, it still offers good wildlife viewing, particularly for waterbirds and the occasional caiman. The historic Demerara Harbour Bridge crosses it just south of Georgetown.
The Mahaica River
The Mahaica River is famous for Hoatzin viewing — this is one of the most reliable places in Guyana to see the national bird. Just 40 minutes from Georgetown, it's perfect for half-day tours focusing on this prehistoric bird species and other riverbank wildlife.
Hoatzin Hot Spot
The Mahaica River offers the easiest access to see Guyana's national bird. Tours depart early morning when Hoatzins are most active. You'll also spot kingfishers, herons, caimans, and possibly capybaras along the banks.
The Rupununi River System
The Rupununi and its tributaries in the south are where river tours reach their peak. This is giant otter territory — families of these endangered animals can be observed fishing, playing, and raising young in the clear waters. The Rewa River and surrounding creeks are particularly famous.

Best Time for River Tours

|---|---|---|
| Dry Season | Sept-April | Lower water concentrates wildlife, easier otter viewing, clearer water |
| Wet Season | May-August | High water, access to flooded forest, different wildlife patterns |
| Peak Wildlife | Oct-Dec | Optimal conditions, otters raising pups, excellent caiman viewing |
Pro Tip
For giant otter viewing, time your visit for the dry season when falling water levels concentrate fish — and the otters that hunt them. Early morning tours (departing at first light) offer the most active wildlife viewing.
