Solomon Islands
Megapodes bury their eggs in black sand that an active volcano keeps warm from below.
Savo rises from Iron Bottom Sound with steam, warm ground and forested volcanic slopes. Its best-known birds are megapodes, which bury their eggs in geothermally warmed soil rather than incubating them in a nest.
Savo rises out of Iron Bottom Sound as a steaming, forested volcanic island with a documented history of eruption. Its megapodes bury their eggs in ground the volcano keeps warm, leaving the heat to do the incubating. Egg harvesting follows customary rules, and the thermal ground is genuinely hot underfoot. Village guides lead the walks to the nesting grounds, the hot springs and the interior. Savo last erupted in the mid-1800s and has steamed quietly ever since.
Solo
Savo is a short crossing from Honiara, and village guides walk visitors up the island, arranged through the hosts like everything here.
Couple
A few hours inland through hot springs and warm ground, and the island is small enough that you are back on the coast by the afternoon.
Friends
The climb towards the crater is the stretch worth having company on, warm ground underfoot most of the way.
Cassava and megapode egg cooked in volcanic hot water, taken only with a host who follows the customary harvest rules.
Fish out of the sound, grilled at the village that walks you up the island.
