Seacology offers one-of-a-kind island ecotourism adventures throughout the world.
When you join one of our expeditions, you won’t travel like an ordinary tourist. Instead, you’ll visit a Seacology project and meet local people. Most important, you’ll see how we’re making a difference, both by conserving island habitats and helping island communities.
With a small group of Seacology supporters, you’ll also explore unforgettable island environments, from the coral reefs of Fiji to the rainforests of Borneo. You’ll stay at luxury resorts and see amazing cultural sites. And depending on the destination, you’ll have opportunities to scuba dive, snorkel, hike, or kayak.
In 2023, The Travel ranked our travel program second on its list of the top ten ecotourism providers, describing Seacology as “one of the best sustainable tour companies in the world.”
We give Seacology Fellows the first chance to sign up for our trips. Then we announce the expedition in our email updates and open it to everyone. (If you’re not on our email list, you can subscribe here.)

Past Expeditions
Seacology has led dozens of trips to islands around the world, introducing hundreds of people to new cultures and helping them experience awe-inspiring landscapes and wildlife. Here are just a few highlights.
Fiji
In our second travel partnership with the California Academy of Sciences, supporters of both organizations were introduced to the natural beauty and welcoming culture of this fascinating South Pacific country.
Chile
From mysterious, remote Rapa Nui (Easter Island) to the dramatic glaciers of Patagonia, this trip was full of wonders. On Quinchao Island, travelers saw how a new coastal reserve will protect endangered shorebirds.
Borneo
Travelers stayed at a beautiful eco-lodge in the forests of Malaysian Borneo, and saw orangutans, elephants, and much more. Visiting a Seacology project, they ate, sang, and danced with villagers and planted trees along the river to mark the day.
