   *Ulithi's untouched coral reefs

   *Yap's Manta Ray Sanctuary

   *Nesting sea turtles in Ulithi

   * A profusion of fish

   *Authentic cultural immersion

This expedition is offered in collaboration with Hawaii Wildlife Fund whose co-founder  Hannah Bernard will lead the expedition.  Hannah has led four previous expeditions to Micronesia including one to Yap and Ulithi in 2016.

Our adventure begins in Yap, known as the best place for seeing manta rays year round on a consistent basis.  We visit the protected channels where manta rays congregate to be cleaned by small reef fishes called "cleaners."   Yap leads the world in manta ray conservation with the establishment of the Manta Ray Sanctuary in 2008.

The reefs and channels surrounding the island are home to a spectacular array of fish.

Yap is widely known for its strong traditional values, and as the land of stone money.

We explore the main island of Yap, visiting the traditional houses, and seeing some the stone money for which Yap is famous. Our cultural tour includes opportunities to see local crafts made on the island.  Photographic opportunities are exceptional. 

Located approximately 100 miles northeast of Yap State, Ulithi Atoll has 200 miles of reef, and the lagoon is surrounded by 36 tropical islands, only four of which are inhabited.

The clear, warm waters abound with coral and colorful tropical fish.  This remote, untouristed area offers exceptional  snorkeling from the beach as well as from our by snorkeling boat anchored off uninhabited islands.

The atoll hosts the most important nesting grounds for green sea turtles in all of Micronesia. A highlight will be visiting the remote Turtle Islands to witness the nesting activities of green turtles.

We provide a community service with a marine debris beach clean up to help restore nesting sea turtle habitat.  Our trip coincides with peak nesting activities and we will learn about monitoring activities from our local guides.

The Ulithi community continues to practice their traditional lifestyle, and hosted by our local nonprofit partner organization we can experience traditional cultural practices including dances and the weaving of lava lava.
