It's 10.30am and the shop assistant is already sweating. The transaction isn't a tough one. I'm an easy mark, armed with American dollars and a consumer's hunger for one of the traditional Berbice chairs on sale, complete with planter's arms and chintzy upholstery, but the simple act of breathing here induces a sauna-like glow.
"So you been to Berbice then?" says the salesman with a slow West Indian drawl. I explain that I haven't visited the former sugar plantation town in Guyana's interior, which produces the eponymous chair. "But I am going down the Essequibo River," I offer. "Into the interior and the Amazon."
He draws a sharp breath through his teeth. "Big trip," he says. "I never seen that part of me country. Never left the coast."
Most of Guyana's 750,000-strong population haven't visited the interior of their country. Much of it is uninhabitable, carpeted in rainforest and only navigable by boat, prohibitively expensive 4x4 vehicles or canoe. Inaccessible it may be, but Guyana offers plenty of inspiration for the pioneer tourist. And there is a surprising number of stylish places to stay. We're not talking Ian Schrager-design here but old colonial ranches and plantation houses that remain the same, and under the same owners, as decades before. And in a country where tourism is in its infancy you have these places to yourself. Imagine taking an African safari in the 1920s, staying as a guest of the local British expat, and you have a sense of what "life in the interior" can be like for the adventurous traveller.
Bordering the Caribbean, Brazil, Venezuela and Suriname, the country enjoys a varied ethnic mix unique to Latin America, and has a dramatic colonial history that includes lengthy periods of Dutch and British rule. With more money and more commitment from the government and outside investors, the place could be a hub for specialist tourism, from holidays exploring the country's sugarcane history, to sports fishing on its various Amazon tributaries.
For food alone the country is a must-visit, with cuisine that mixes Amerindian, West Indian, British, Dutch and even Chinese and Indian culinary traditions - the latter two having arrived with indentured workers during British rule. But Guyana is a long way from neatly packaging its colonial history in tidy museums and organised tours. Since independence from the British in 1966, the economy has been in gradual decline and the locals have been leaving in droves. Today, tourism mainly caters for returning Guyanese diaspora.
So why come here? Because no one else does. In a country that has to import more or less everything to survive, wildlife is the one resource it has in unspoilt abundance. A handful of tours are beginning to help the adventurous traveller enjoy these riches, and bring their much-needed wealth. Most tours begin or end at the country's stellar sight: Kaieteur Falls, the largest single-drop falls in the world.
Getting here involves travel in a style fitting for this former British colony, by privately chartered plane that puts down on top of tepuis (table top) mountains, where 30,000 gallons of water per second tumble 741ft to the forest floor.
Rare wildlife may be abundant in Guyana - jaguar, harpy eagle, giant anteaters - but tourists are not. Travelling deep into Guyana's interior we see not one other group. The country is ours for the exploring; by boat along the Essequibo River, by foot or 4x4 on dirt tracks into the jungle and savannahs where former cattle ranches, sugar plantations and an Amerindian village guesthouse provides us with beds for the night and expert nature guides during the day.
That Guyana was the setting for Conan Doyle's Lost World seems fitting for a place that no one seems to be able to locate on a map. When asked, most British friends failed to place it within the right continent, mistaking Guyana for an African nation. Once here, the place refuses to be pinned down. It's in Latin America but English, not Spanish, is spoken and the slow pace of life is more akin to the West Indies.
Each place we visit along the river is distinct from the next. At Surama, an Amerindian village located where Guyana's rainforest meets its sun-bleached savannah, our host is the village Touchau (chief) who speaks Macushi Indian and takes us for a dawn nature tour in a dugout carved from purple heart wood.
Further south, we are met by Dianne McTurk, a Scottish colonial descendent who runs a giant river otter rehabilitation centre, with a lodge that wouldn't look out of place in East Africa. Back upriver, our last stop before Georgetown, the capital, is Shankands, a Caribbean plantation house-style lodge set in manicured grounds along the Essequibo. From a whitewashed porch, seated in one of those elegant Berbice chairs, I watch an impromptu game of cricket between a group of Guyanese expats and the Amerindian staff. Their chatter is momentarily drowned out overhead by a squawking pair of scarlet macaws.
Where am I? Armed with a rum and coconut water I decide, for a moment, it doesn't really matter.
