We begin our tour of eco-friendly hotels on Koh Tao with The AVA Resort, a true gem among the island's sustainable accommodations. Set in a picturesque location, this resort offers guests an unforgettable experience combined with environmental care.

The AVA Resort stands out above all for its approach to environmental sustainability. The property uses solar energy, employs water conservation systems and promotes recycling. Rooms are decorated using natural, local materials, which not only supports the local economy, but also minimizes the carbon footprint.

Guests can choose from modern and spacious rooms, many of which offer breathtaking sea views. As one reviewer points out: 'The rooms are modern and clean, with daily cleaning service. We opted for a room with a sea view, which is a must if your budget is tight for that, as the view is out of this world.

One of The AVA Resort's greatest assets is its infinity pool, which allows guests to enjoy a panoramic view of the bay. It's the perfect place to relax and contemplate the beauty of the surrounding nature. The resort also offers a café where you can enjoy local delicacies prepared with organic ingredients.

The location of the resort is worth noting. It is located on top of a hill, which provides spectacular views, but can be challenging for those with limited mobility. However, the resort offers a free shuttle service, making it much easier to get around the island.

The AVA Resort also stands out for its commitment to the local community. It organizes environmental education programs for local children and supports local environmental initiatives. This makes staying here not only a luxury vacation, but also a contribution to the sustainable development of the island.

Prices at The AVA Resort are slightly higher than the island average, but as guests note, the quality and experience fully justify the difference. It's worth booking your stay in advance, especially during high season, as the resort is very popular with eco-conscious travelers.

Another property that deserves special mention in our guide to eco-friendly hotels on Koh Tao is Phandara Luxury Villas. This exclusive villa complex offers guests a luxurious getaway in complete harmony with the surrounding nature.

Phandara Luxury Villas is a true oasis of tranquility nestled in the lush tropical jungle of Koh Tao. Each villa has been designed to maximize the natural beauty of its surroundings while minimizing environmental impact. The use of local, renewable building materials, such as bamboo and teak, not only gives the villas a unique character, but also supports sustainable construction practices.

Guests can choose from spacious, private villas, each with its own infinity pool overlooking the sea. As one satisfied guest notes: 'Fantastic private villa tucked away in the jungle. The hosts have thought of everything you might need. The perfect way to get away from the busy beaches and watch your own sunset with a glass of chilled wine.

Phandara Luxury Villas stands out for its approach to ecology. The resort uses solar energy to heat water, employs rainwater harvesting systems and promotes recycling. Guests are encouraged to use eco-friendly means of transportation, such as electric bicycles, which the resort provides free of charge.

One of Phandara Luxury Villas' greatest strengths is its personalized service. The hosts go to great lengths to meet the individual needs of each guest, offering a range of services such as private candlelit dinners on the villa's terrace and organizing tours of the island with an emphasis on ecotourism.

The resort also offers a range of amenities that allow guests to enjoy the beauty of the island without leaving the grounds of the complex. Stand-up paddle boards, kayaks and snorkeling equipment are available, allowing guests to explore the nearby coral reefs in a responsible manner.

Prices at Phandara Luxury Villas are higher than the island average, but as guests point out, the quality of service, privacy and memorable experience fully justify the difference. One reviewer concludes: 'Super hosts, super location, great finishes. I highly recommend staying here for a few nights.'

The last, but certainly no less impressive property in our guide to eco-friendly hotels on Koh Tao, is Jamahkiri Dive Resort & Spa. It's a place that perfectly combines a passion for diving, concern for the environment and a luxurious wellness experience.

Jamahkiri Dive Resort & SPA is located on a picturesque cliff, offering guests breathtaking views of Shark Bay. The resort has been designed to have minimal impact on the surrounding environment. It uses solar energy, employs advanced water purification systems and promotes zero waste practices.

One of Jamahkiri's greatest assets is its dive center. The resort offers a range of courses and diving expeditions, with a special emphasis on environmental education and coral reef conservation. As one guest notes: 'Amazing place with great views and excellent dive instructors. Snorkeling right next to the hotel is breathtaking.

For those who prefer to relax on land, Jamahkiri offers a luxurious spa where you can enjoy treatments using natural, organic products. The infinity pool overlooking the sea is the perfect place to unwind after an eventful day.

The resort also stands out for its approach to gastronomy. The restaurant serves dishes prepared with local, organic ingredients, often sourced from the resort's own garden. The menu includes many vegetarian and vegan options, which is appreciated by environmentally conscious guests.

Noteworthy is Jamahkiri's commitment to protecting the local ecosystem. The resort regularly organizes beach and coral reef cleanup campaigns in which guests can participate. In addition, it conducts educational programs for the local community on the importance of protecting the marine environment.

One challenge that guests point out is the resort's large number of stairs. As one reviewer notes: 'A bit of a lot of stairs, but something for something. The views are worth it. The resort does, however, offer shuttle services on the premises, making it easier for those with limited mobility to get around.

Prices at Jamahkiri Dive Resort & Spa are higher than the island average, but as guests point out, the quality of service, unique location and memorable experience fully justify the difference. One guest concludes: 'A luxury hotel on Koh Tao, simply fantastic. Probably the best on the whole island.'
