For two hours we drive towards a spectacular electric storm creating monochrome fireworks on the velvety horizon.
It’s so far away we don’t so much as flip the windscreen wipers as we pass through villages called Blackman Eddy and Boom.
The evocative names tell stories from a logging past when timber and gum were Belize’s most important industries. Now, this Central American country draws tourists to its Caribbean-facing coast for diving on part of the world’s second largest barrier reef system.
Not that it’s all about the sea. On our first morning my tour group is hand-cranked on a floating bridge across a river to Xunantunich archaeological site.
I climb to knee- weakening height up a terraced pyramid and cling to stones set like teeth along the top for a jungle view.
The Mayan site was laid out to resemble the cosmos with carvings of a jaguar in the underworld zone and a sun god in a stucco frieze to the west.
Overpopulation and infrequent rain prompted ancient leaders here to desperately increase their sacrificial rituals.
They tried bloodletting from their genitals, setting their gory offerings on fire so serpent-like twists of smoke might hiss their pleas to the gods.
At Bocawina national park I’m involuntarily involved in bloodletting myself as bugs find the gaps in my repellent.
I’m distracted from their feasting as, heart in my mouth, I watch a braver member of our party try slippery rappelling down a high waterfall. The park also offers tubing, zip lining and kayaking.
Our base is the laid back strip of Hopkins Village. In the beachfront Love on the Rocks restaurant at Parrot Cove Lodge we turn kebabs of fresh seafood on lava slabs heated to 370C.
Next morning we depart from the jetty for a snorkelling adventure at Silk Caye. Conch shells litter the ocean floor under the turquoise waters here and our guide lifts one to reveal a lobster’s hiding place.
It’s at a deeper site that I meet the big boys vying for discarded scraps from the fishing boats’ catch. My breathing makes rapid rasps through my snorkel as I’ m passed by numerous nurse sharks, then a turtle the size of a cow.
