Low-Impact Environmentally Friendly Resorts in Tonga

Let us save you the trouble of only realising you want to do more to protect the oceans and pristine islands of Tonga after your trip by suggesting to book into one of the eco-friendly accommodations before! Many of Tonga’s resorts offer off-the-grid experiences using renewable energy sources, locally sourced food, local timbers for construction, implemented planting programs, water sourced by rain, and composting toilets. We list some of those low-impact accommodations in this list of the best eco-resorts in Tonga!

Remember, staying in low-key guesthouses in villages and supporting the local community can be another more sustainable way of travelling, so don’t rule out some of Tonga’s guesthouses. We go into more detail in How to Pick the Best Eco-Stay in Tonga for You.

Note that Tonga is an ever-evolving country, especially when it comes to accommodation. With that in mind, some of the services accommodations provide are known to change without notice. If there is any information needing an update in the listings below, feel free to reach out!
