Madai Caves is another important place for birds' nests. The village at the entrance of the largest cave comes alive twice a year when the Idahan community comes to harvest the birds' nests from various parts of the caves. It is a special communal event, almost like a festival.The harvesting is a dramatic event with the men risking their lives to prise precious nests from the cave roof. Nowadays, the harvesters are hired. The Idahans have held their rights to the Madai Caves for over 20 generations. To visit the caves, permission must be obtained from the Idahan elders. Visitors may visit the District Office in Lahad Datu town to make prior arrangements for entrance permission on their behalf.
All buses between Lahad Datu and Semporna or Tawau will pass the turn-off to the caves. From here, you'll be able to find a minivan to take you to the caves. But you might have to walk back out to the highway to catch your ride back.
