Galathea National Park, National park in Great Nicobar Island, India.

Galathea National Park covers about 110 square kilometres of Great Nicobar Island, separated from Campbell Bay National Park by a 12-km forest buffer. Its vegetation is tropical and subtropical moist broadleaf forest, and the park is named after the Danish vessel Galathea, which surveyed for minerals here in 1845–47.

The park was created in 1992 to protect the island's natural ecosystems from human impact. This status made it one of the region's most important conservation projects.

The park's name comes from the Danish vessel Galathea, which surveyed Great Nicobar for minerals in 1845–47. The leatherback turtle nests here from February to December, and the Nicobar pigeon, megapode and giant robber crab live in the rainforest. The island's inhabitants experience only summer and monsoon, never winter.

Getting there takes about two days by ship from the mainland, so plan accordingly for the journey. You will need official permission to enter and should expect basic facilities in this remote location.

Giant leatherback turtles come ashore between February and December to lay eggs in the sand. This is one of the few remaining places where this natural event still happens on a large scale.
