Solomon Islands
Hawksbill turtles nest on beaches three communities agreed to stop hunting.
After dark a hawksbill hauls herself up the sand, and a ranger crouches at the treeline recording her tag by red torchlight. Waves, breathing, the scratch of a pen: the Arnavons exist for exactly this.
The Arnavons hold one of the western Pacific's important hawksbill nesting sites, on beaches now patrolled by rangers. The Kia, Katupika and Wagina communities set aside long-standing disputes over these waters to protect them together from 1995, and in 2017 the area was declared a national park. Rooms are simple, and boats come in from Kagau or Suavanao. Nesting and hatching run to the turtles' season rather than a visitor's, and ranger rules govern every beach.
Solo
Rangers take small numbers, so one visitor slots into a patrol far more easily than a group does.
Couple
Nesting happens at night and on the turtles' schedule, which means long quiet evenings and a real chance of seeing nothing at all.
The field station's kitchen is self-catering: what you eat on a turtle island is what you carried in.
Larger groups can have catering arranged, booked one to two weeks ahead.
