the globe says
Guyana
Fly to Georgetown via Miami or Panama, then a twelve-seater over unbroken rainforest to the falls' own airstrip.
Georgetown guesthouse, or the bare-bones lodge at the falls if you want the place to yourself overnight.
A waterfall four times Niagara's height dropping into pristine Amazonia, no railings, no crowds, golden frogs in the bromeliads, and swifts that dive through the torrent at dusk.
If you can, book the overnight — when the day flights leave, you and the ranger have one of Earth's great sights entirely alone.
September to November for full flow
English is the language — Guyana is South America's anglophone outlier.
Wild Coast by John Gimlette — the Guianas, the strangest corner of South America.
The Rupununi savannah — vaquero country, giant anteaters, and Karanambu's otters.
Georgetown requires city sense, especially after dark — taxis, not walks.
