Leading Nature Travel Expeditions Since 1969
For more than 55 years, Oceanic Society nature expeditions have brought people face-to-face with some of the world's most extraordinary places and wildlife—not just to observe, but to actively support in their protection.
We are pioneers in naturalist-guided experiential travel for nature lovers, offering eco-tours, snorkeling trips, wildlife tours, whale watching, and more. We believe experiences are richer when shared with others, which is why we specialize in small-group trips for travelers eager to connect with nature and support conservation.
Your Travel Advances Ocean Conservation
When you join an Oceanic Society expedition, your travel directly supports plastic pollution cleanup, local conservation projects, and coral reef restoration. These meaningful conservation initiatives are made possible through the Expedition Impact Program, funded by Oceanic Society and partners who share our mission for every booking made with us.
