Mexico’s Yucatán Peninsula is an atmospheric reserve of Spanish-colonial and Mayan heritage – a longtime favourite of clued-in New Yorkers taking hacienda holidays and of adventurers drawn to the mystery of millennia-old ruins and chalcedony-coloured cenotes (the limestone sinkholes that were the Mayans’ primary freshwater source and considered sacred). One is at the centre, literally and figuratively, of Chablé (www.chableresort.com;from $850). It opens in May and is about 20 minutes’ drive from Yucatán state’s languid capital, Mérida. The all-villa retreat will be the first to leverage a cenote to wellness ends, with a full-service spa constructed into the surrounding limestone. The deep jungle setting provides the (total) privacy, and the sizeable organic vegetable gardens supply the chefs, who will prepare extensive raw-food menus. There’s also what’s touted as the largest fine tequila collection in the world, available to those with less health-orientated leanings.
