Canggu, a formerly quiet bit of Bali is now buzzing with casual cafés serving vegan breakfast bowls to sun-bleached digital nomads, all of them designing, writing, coding or consulting with only a MacBook and a glittering sea view. Hot hotels have quickly followed: The Slow offers retro-modernist suites and a soundtrack by LA-based Reverberation Radio. And newest opening Como Uma Canggu has just upped the ante with duplexes packing their own rooftop pools. By night, Canggu hipsters head for The Lawn, a laidback, barefoot beach club serving up old-school hip-hop and hibiscus cocktails. They pair best with a temperate summer evening, when Bali is in its sunny, surfie prime.

Sustainable travel tip: Overtourism in Bali is well documented, and its attendant pollution most severely affects locals, who make little money from the tourism boom (the lion’s share of that wealth goes to the government and foreign investors). JED is an ecotourism network owned by the communities of four local villages, offering trips that not only bring you up close to a more authentic Bali, but give back to the Balinese.

While it doesn’t exactly get hot in Newfoundland, July is the beginning of the Canadian island’s balmiest season. And as the sort of place you want to get out and about — whether scouring woodland for gourmet specialties like lovage and spruce tips, or learning the local art of cod-jigging from a hardy fisherman — highs of 18C makes things infinitely more pleasant. The easternmost of Canada’s provinces, on a limb in the Northern Atlantic, it’s a thrillingly rugged hinterland of puffins, sea cliffs and Viking legends; the sort of vast frontier a whale might breach right by your kayak, or where immense, glacial-blue icebergs bob nonchalantly past. A newly minted culinary rep means rich rewards after all that fresh air. In provincial capital St John’s, Raymond’s foraged menu (seabuckthorn, Acadian sturgeon) has been hailed the nation’s best. Or get yourself invited to a local beach 'boil-up', where sea urchin and mussels are plucked fresh from rock pools.

Sustainable travel tip: The architecturally masterful, boutique Fogo Island Inn was conceived as a social business, employing local people and celebrating their traditions (furniture designed with local artisans; community host-led tours). All profits are funnelled back into the community and renewable energy, rainwater catchment systems, recycling and composting are all in place. The restaurant focuses on local, organic, seasonal and foraged food.

Picking the most beautiful Greek island is like picking the most big-headed Gallagher brother: virtually impossible. But if we were forced, Naxos in the summer just might be the answer. The largest of the Cyclades, its sandy beaches run the gamut from family-friendly frolickers in the west (Agios Prokopios), to the south’s hidden wildlings, where you can ride horses over dramatic dunes (Plaka) or brave powerful winds on a kiteboard (Mikri Vigla). And though not exactly a hidden gem, the pace remains pleasantly drowsy, whether kicking back in beach bars or supping at mountain village tavernas. At the latter, you’ll be drowsier still after generous sloshes of homemade wine and local citron liqueur.

Sustainable travel tip: Catch a ferry from Athens to Naxos and arrive on the island in a little over four hours.

It’s not just insanely beautiful beaches and postcard-blue Caribbean, Mexico’s dazzling tropical coast is also a trove of adventure. Flee Cancun for Isla Mujeres in July when the island hosts the annual Whale Shark Festival and hundreds of sharks gather offshore. The event raises awareness about conservation, while allowing swimmers to share the water with the gentle giants in a sustainable manner. Then head down to Tulum (or Isla Holbox) where days start with sun salutations and end on toes-in-the-sand candlelit dinners. Hot reservations are easier to come by as this is technically rainy season; July, however, typically heralds a reprieve from the torrent.

Sustainable travel tip: Where Tulum’s not-so-sustainable practices have made headlines, Isla Holbox’s MO is small-scale and local. The lack of paved roads all but mandates getting around by bicycle; the most convenient way to arrive is by 30-minute ferry from the mainland; its restaurants, bars and stores are locally owned; and single-use plastics have been banned since 2018.
