Pool with a view Kenya
When you take a dip in the spring-fed pool at Sarara in northern Kenya, you look out onto an arc of forested peaks on the remote northern side of the Mathews Mountains. Surrounded by 300sq km of land protected by the Namunyak Wildlife Conservation Trust, the setting alone is majestic enough, but there's more – the infinity pool overflows into a watering hole where animals come to drink. So you may find yourself enjoying the view with an elephant or two. +254 720 888 111, safarilink-kenya.com
Ecolodge Egypt
Deep in the Sahara Desert, on the edge of the Qattara Depression, Adrère Amellal ecolodge in Siwa oasis is a mini-medina, its mud houses made from local materials. There's no electricity and no reception, just a sense of peace and simplicity. Meals are made from homegrown produce and served on a terrace, by a pool or on the sand. If you tire of the panorama, you could take a dip in Siwa's Roman pool, stroll through palm-shaded gardens, visit the Temple of the Oracle of Amun, or ride the smooth waves of the Grand Sand Sea by four-wheel-drive. +202 2736 7879, adrereamellal.net
Voluntourism Brazil
Do you know the difference between Samba no Pé and Samba de Gafieira? Or when to recognise the change in tempo from the Brazilian zouk to the lambada zouk?

Wildlife Namibia
Few people ever see a cheetah in the wild. As well as being one of the shyest of the big cats, it's also one of the most endangered: perhaps only 10,000 remain, around a quarter of those in Namibia. The Africat Foundation offers the best cheetah-spotting odds anywhere outside a zoo. From the 223sq km Okonjima guest farm near Otjiwarongo, where you stay in luxurious thatched chalets, guides will take you close to cheetahs devouring a kill, or you'll follow on foot as they track impala. +264 67 687 032, okonjima.com

Overlooking one of the Cape's most spectacular bays, Grootbos Nature Reserve in South Africa is a five-star eco-hotel and reserve that's home to more than 6,000 endemic plant species. An area of farmland surrounding the hotel has been cleared of invasive species and replanted with indigenous fynbos, the most diverse floral system on earth.

Sailing Grenadines
For many, the Grenadine islands in the Caribbean are the ultimate holiday destination: immaculate white beaches, balmy temperatures, turquoise seas and star-strewn night skies. A good way to see the islands is onboard Fab Safaris' sleek catamaran Vaza Vezo. Powered along by large sails, it is a low-impact means of transport, and you'll enjoy treks in the rainforests, scuba diving, visits to turtle sanctuaries and browsing for arts and crafts in local villages. Then relax in the boat's luxurious cabins. fabsafaris.co.uk
Adventure Bangladesh
In the dense rainforests that line Bangladesh's southeastern border with Burma and India, there are half a million indigenous people belonging to 14 different tribes, yet few tourists make the effort to visit the villages. For those who do, Bangladesh Ecotours takes guests into the Chittagong Hill Tracts to stay with tribes, sharing in feasts, shopping for handicrafts, and often finding themselves the audience for an impromptu song and dance. There's usually the chance for hill trekking, birdwatching, river cruises or visits to nearby temples. bangladeshecotours.com

One of the most important wetlands in the world, the Everglades is a vast sodden expanse at the southernmost tip of Florida.
