As some destinations around the world struggle with <a href="https://www.thenationalnews.com/travel/2024/01/11/antarctica-overtourism/" target="_blank">overtourism</a>, many travellers are vowing to ensure their holidays are a force for good. Preserving land and water for the betterment of the environment and of the communities that live in wildlife-rich destinations not only benefits those places directly but also helps to preserve beautiful spots for tourists to continue visiting in the future. Several organisations offer conservation-based trips that give travellers the chance to get close to nature and leave behind a positive mark. Here are five of the best to bookmark for 2025. Travellers can experience what it’s like to be a tropical marine biologist on a trip to <a href="https://www.thenationalnews.com/world/uk-news/2022/03/23/the-duke-and-duchess-of-cambridge-go-scuba-diving-in-belize/" target="_blank">Belize</a> from February 22 until March 1 run by MarAlliance Expeditions.

Volunteers can join locals and researchers at the Tortuga Marina and stay in a small house inside the sanctuary. There, they will take part in midnight beach patrols to collect newly laid eggs before relocating them to safe nests where they will be protected from predators. Early in the morning, volunteers can join the team releasing newly hatched olive ridley, hawksbill and green turtles into the ocean. Travellers will be taught how to do this responsibly, ensuring that human interaction does not disrupt the turtles' memory when the females need to return to the beach to nest. Volunteers are welcome from June to February and for periods of no less than 10 days, with a $25-a-day fee going towards food and lodgings.
