The Georgetown to Lethem Road: Guyana's Great Interior Highway

460 kilometres of rainforest, red laterite, and open savannah — the road that connects Guyana's coast to the Brazilian border.

Updated: April 2, 2026 14 min read Travel & Infrastructure

There is a road in Guyana that takes you from the flat, sea-level coast where 90% of the population lives, through one of the last great untouched rainforests on Earth, across a vast savannah that feels like the African plains, and delivers you to a river that forms the border with Brazil. It is roughly 460 kilometres long. It takes anywhere from 12 to 17 hours to drive. For much of its length, it is unpaved red laterite that turns to mud in the rain and dust in the sun.

The Georgetown to Lethem Road is not just a highway. It is the spine of Guyana's interior, the lifeline for indigenous communities and mining camps, the path through the Iwokrama Rainforest, and — if the government's plans come to fruition — the future corridor linking the Caribbean to South America. It is one of the most remarkable drives on the planet.

The Dream of a Trans-Guyana Highway

Guyana is a country of contradictions. Its coastline is densely settled — almost the entire population lives on a narrow strip of land along the Atlantic. But the interior, which accounts for more than 90% of the country's land area, is vast, sparsely populated, and extraordinarily rich in natural resources: gold, diamonds, bauxite, timber, and some of the most biodiverse ecosystems on the planet.

The dream of connecting the coast to the interior — and beyond, to Brazil — has driven Guyanese infrastructure planning for decades. A proper highway from Georgetown to Lethem would open up the interior for development, provide reliable access for indigenous communities, enable year-round tourism to world-class rainforest and savannah destinations, and create a trade corridor between the Caribbean and South America's largest economy.

It is a dream that is finally, slowly, becoming reality.

History of the Road

The route from Georgetown southward into the interior was not built as a single project. It evolved over time, driven by different needs in different eras:

For most of its history, the road south of Linden has been unpaved — a laterite (red earth) track that ranges from passable to impassable depending on the season, the rainfall, and how recently it has been graded.

The Route: Section by Section

Georgetown to Linden

~100 km | 1.5-2 hours | Fully Paved

The journey begins on the East Bank Demerara highway heading south from Georgetown. The road is paved and in good condition, passing through residential communities along the Demerara River before climbing slightly inland to Linden. This is the only fully paved section of the entire route. Linden, Guyana's second-largest town, is the last place to reliably stock up on fuel, food, and supplies before heading into the interior.

Linden to Mabura Hill

~122 km | 3-5 hours | Being Upgraded

South of Linden, the pavement ends and the laterite begins. This section passes through dense tropical forest, crossing numerous creeks on wooden bridges. The road can be rough, with deep potholes and corrugation. Mabura Hill is a former logging town and a fuel stop. A 122 km section from Linden is currently being upgraded and paved as part of the Linden-Lethem highway project.

Mabura Hill to Iwokrama

~80 km | 2-3 hours | Unpaved Laterite

The road enters the Iwokrama Rainforest, and the landscape transforms. The forest closes in on both sides — towering trees form a canopy overhead, and the road becomes a corridor through one of the most pristine wilderness areas on Earth. This is where the real adventure begins. The Iwokrama River Lodge and the Atta Rainforest Lodge are located along this section.

Iwokrama to Annai

~70 km | 1.5-2 hours | Unpaved Laterite

Emerging from the rainforest, the landscape opens dramatically into the Rupununi Savannah — a vast, flat grassland dotted with termite mounds, palm trees, and scattered Makushi villages. Annai is a small indigenous community at the junction where a side road leads to the Rupununi River and various eco-lodges. Rock View Lodge at Annai is a popular stopping point.

Annai to Lethem

~130 km | 3-4 hours | Unpaved Laterite

The final stretch crosses the open Rupununi Savannah. In dry season, the road is dusty but relatively fast. In wet season, sections can be submerged or impassable. The landscape is extraordinary — vast grasslands stretching to the Kanuku Mountains on the horizon. Lethem, at the end of the road, is a small frontier town on the Takutu River, looking across at Brazil.

Driving Conditions

Driving from Georgetown to Lethem is not a casual road trip. It is an expedition. The conditions vary dramatically between seasons and even between weeks:

Dry Season

Sept-April: Road is passable but dusty. Laterite is firm. Creek crossings are shallow. Best time to travel.

Wet Season

May-August: Sections become muddy or flooded. Creek levels rise. 4x4 essential. Some sections impassable.

Vehicle

High-clearance 4WD required south of Linden. Toyota Land Cruiser is the gold standard. Carry spare tyre and tools.

Fuel Stops

Fill up in Linden. Limited fuel at Mabura Hill. Next reliable fuel is Lethem. Carry extra fuel for the journey.

Essential Travel Tips

The Iwokrama Section: Driving Through a Million Acres of Rainforest

The Iwokrama section of the Georgetown-Lethem road is, for many travellers, the highlight of the entire journey — and one of the most remarkable driving experiences on Earth. The road passes through approximately 72 kilometres of the Iwokrama Rainforest, a 371,000-hectare (almost 1 million acres) protected area that is one of the last pristine tropical forests in the world.

Driving through Iwokrama is like entering another world. The forest towers on both sides, with trees reaching 30-40 metres into the canopy. The air is thick, humid, and alive with the sounds of birds, insects, and howler monkeys. Wildlife sightings from the road are not uncommon:

The Iwokrama Canopy Walkway

One of Guyana's premier attractions is located right along the Georgetown-Lethem road. The Iwokrama Canopy Walkway is a series of suspension bridges and platforms rising 30 metres (100 feet) above the forest floor and stretching 154 metres in length. A 15-minute forest trail from the road leads to the walkway.

From the treetop platforms, visitors can observe the mid and upper canopy — a world of birds, monkeys, and epiphytes that is invisible from the ground. Over 12 species of hummingbird have been recorded at the nearby Atta Rainforest Lodge, which serves as the base for canopy walkway visits. Dawn and dusk are the best times for wildlife viewing.

Paving Progress: The Linden-Lethem Highway Project

The transformation of the Georgetown-Lethem road from a laterite track to a modern paved highway is one of Guyana's most ambitious infrastructure projects. The effort is being carried out in phases:

September 2022

Paving work begins on the first 122 km section from Linden to Mabura Hill, funded by the UK Caribbean Infrastructure Partnership Fund (UKCIF) and administered by the Caribbean Development Bank.

Ongoing

Additional sections being planned and funded from multiple sources including the Islamic Development Bank and bilateral agreements with Brazil and other partners.

Target: 2030

Most optimistic completion date for the full highway. The project will cost nearly US$1 billion and require construction of approximately 50 bridges along the route.

When Complete

Travel time from Georgetown to Lethem will be reduced from 12-17 hours to approximately 5 hours. Year-round all-weather access to the interior and Brazil.

The project is more than a road. It is a statement of national ambition. A paved highway to Lethem would transform the economics of Guyana's interior, provide reliable access for indigenous communities that are currently cut off during the wet season, enable year-round tourism to Iwokrama and the Rupununi, and create a trade corridor between Georgetown's port and Brazilian markets.

Environmental Considerations

Paving the road through Iwokrama raises legitimate environmental concerns. Improved access could increase deforestation pressure, illegal mining, and wildlife poaching. The Iwokrama International Centre, which manages the forest, is working to ensure that the road upgrade includes environmental safeguards — speed limits through the forest, wildlife crossings, and restrictions on commercial development. The challenge is balancing economic development with the preservation of one of the world's most important tropical forests.

Lethem and the Brazil Connection

At the southern end of the road, Lethem is a small frontier town of about 3,000 people on the banks of the Takutu River. It is Guyana's gateway to Brazil.

The Takutu River Bridge, installed in 2009, connects Lethem to the Brazilian town of Bonfim in the state of Roraima. From Bonfim, it is approximately 125 km to Boa Vista, the capital of Roraima, on a paved Brazilian highway. The contrast is stark — you drive for 15 hours on red laterite through Guyana's interior, cross the bridge, and hit smooth Brazilian asphalt.

The strategic significance of this connection cannot be overstated. A paved Georgetown-Lethem highway would create a route from Georgetown's port on the Atlantic coast to Brazil's interior — a much shorter path to the ocean for Brazilian agricultural and mineral exports than the current routes through Brazil's crowded southern ports. Former Brazilian President Luiz Inacio Lula da Silva pledged support for paving the road, recognizing the mutual economic benefit.

The planned Palmyra Deep Water Port on Guyana's coast near the Suriname border would complete the corridor — goods from Brazil's interior could travel by road through Guyana to a modern port facility, and then by ship to global markets. It is a vision that could transform both countries.
