CNN  — 

Travelers are more socially and environmentally conscious than ever, seeking to get away safe in the knowledge they’ve had minimal impact on the planet’s resources.

With 2017 named as the United Nations’ International Year of Sustainable Tourism for Development, the spotlight is even more on the tourism and hospitality industry. While a lot of destinations claim to be doing their part to minimize their footprint, there are some who’ve striven to take sustainability to new levels.

Here are 10 of the best global destinations and experiences where vacations don’t cost the Earth:

1. Soneva Fushi, Maldives

Kunfunadhoo was a deserted island in the Indian Ocean idyll of the Maldives until Eva and Sonu Shivdasani built their first resort there, in the process pioneering the trend for environmentally responsible ultra-luxury holidays. If that sounds like a contradiction in terms, the castaway property has proven the doubters wrong and has been fully carbon neutral since 2014.

They recycle 90% of their waste, including 100% of food waste that’s used in their organic gardens, in turn reducing the cost of transporting food. Construction includes building blocks made from Styrofoam packaging, while all glass goes to their on-site studio where it’s turned into works of art. The solar-based system provides all daytime electricity needs and 100% of water used is desalinated.

Soneva – which today has a property in Thailand and a second in the Maldives – also led the way in implementing a mandatory 2% carbon levy on rooms to support their Soneva Foundation which works in developing regions on reforestation and renewable energy projects.

2. Bom Bom Resort, Sao Tome

Bom Bom
Bom Bom Resort on Príncipe Island features 19 beach bungalows surrounded by tropical forest.

Few destinations are as unvisited and untouched as Principe, the smaller of two main islands in the tiny country of Sao Tome and Principe, lying in the Gulf of Guinea off the west coast of Africa.

Only 5,000 people live there, and Bom Bom Resort comprises just 19 bungalows on the beach, surrounded by tropical forest.

World-class scuba diving and hiking in UNESCO Biosphere reserves, visiting cocoa plantations and fishing villages are on the agenda, while Africa’s smallest city, San Antonio, is also there to discover. For many, it’s also the draw of wildlife, from whales to nesting turtles, monkeys and especially birds found nowhere else on Earth.

3. eXtreme Hotel, Kite Beach, Cabarete, Dominican Republic

It’s perhaps unsurprising that one of the world’s kite surfing capitals – Cabarete in the Dominican Republic – is also home to a genuinely ecologically sustainable small hotel. Surfing and yoga, horse riding and hiking are literally on the doorstep for those not into kite surfing.

The property is 100% solar powered and purposefully not air-conditioned, but uses intelligent ventilation to make the most of the naturally windy beach to circulate cool air.

Rainwater collection systems are used to manage water consumption and an organic farm has 2,000 trees to further offset carbon emissions, in addition to providing local, seasonal produce. The hotel also aims to empower the local community through education, training and work opportunities for local Dominicans who number more than 70% of employees.

Wildlife-focused outings include a canopy walkway high above the forest floor, boat trips and visits to the Gamitana Model Farm, where ITA works in conjunction with local communities.

5. Best of Myanmar Tour, Intrepid Travel

Intrepid Travel promise big adventures to small groups, all under the umbrella of genuinely responsible travel. Their tour of the best Myanmar has to offer stresses that sustainable tourism is critical to preserve the relatively new and underdeveloped destination.

This means their Myanmar trip is fully carbon offset, to the tune of 577 kilograms per passenger.

They use local transportation and accommodation, including a stay at the country’s first community-based tourism project in Myaing where local villagers provide meals and activities, in a project run by ActionAid.

6. Bushmans Kloof Wilderness Reserve, South Africa

Bushmans Kloof
Bushmans Kloof is a sustainable reserve in South Africa's Cederberg Mountains.

Bushmans Kloof Wilderness Reserve is an 18,000-acre wildlife reserve lodge 170 miles from Cape Town in the Cederberg Mountains. Conservation and working with communities are common threads among lodges across Africa, but they take it up a notch at Bushmans Kloof.

There’s waste water processing, sustainable organic farming and energy-saving initiatives, but it’s through protection and reintegration of endangered species that they’ve made their mark. Notably, the reserve is home to the Cape Mountain zebra, saved from the brink of extinction, while there are more than 130 rock-art sites, which are more than 10,000 years old.

Extensive community participation includes supporting schools, clinics, youth camps and even the refurbishment of a museum.

7. Turtle conservation, Kyrenia, North Cyprus

The northern coast of the Mediterranean island of Cyprus is largely unspoilt, with Alagadi Beach a particular draw for a special type of visitor – endangered green and loggerhead turtles.

It’s estimated that as few as 400 green and 2,000 loggerhead females breed in the entire Mediterranean, so conservation work by the Marine Turtle Research Group, led by Britain’s Exeter University, is critical.

Volunteers are welcome, primarily students from undergraduate to PhD level, but non-students are also accepted. It’s a long-term commitment – up to three months – and all volunteers need to contribute to cover food and accommodation. Given issues including habitat loss and climate change, the odds against young turtles making it to adulthood are as low as one in 1,000.

Costa Rica is blessed with some of the most biodiverse ecosystems on earth.

They have also planted hundreds of native trees, reducing their energy consumption by over 90%.

Four high-spec houses clad in cedar offer amenities including private hot tubs, while there’s an indoor heated swimming pool, gym and play area. Five acres of woodland paths allow for exploration.
