Agencies in the Commercial Center arrange circle island tours and fia fia feasts for groups of at least eight persons.
Local guides take visitors to Ulupaka and Anatoloa caves. Ulupaka (near Lakepa) is over a kilometer long and coated with black fungus, so be prepared to get a little dirty.
Guided three-hour hikes in the Huvalu Conservation Area are also offered. Unfortunately, some trips involve the capture of endangered coconut crabs. The guides usually require at least five clients to run a tour.
The Niue Tourism Office in Alofi's Commercial Center has a good selection of brochures and can answer most questions about the island. They also book activities. Ask for the free Jasons map of Niue.
The post office in the Commercial Center sells a 1:50,000 topographical map of Niue.
The coconut crab Birgus latro is a nocturnal creature that lives under logs, in holes, or at the base of pandanus or coconut trees. The females lay their eggs in the sea and the tiny crabs float around a few months, then crawl into a seashell and climb up the beach. When a crab is big enough, it abandons the shell and relies on its own hard shell for protection. Its food is ripe pandanus or coconut. The crab will appear dark blue if it's a coconut eater, rich orange if it feeds on pandanus. First it will husk a coconut using its two front claws, then break the nut open on a rock. It might take a crab two nights to get at the meat. Coconut crabs can grow up to three feet across. Although tasty, they are endangered in much of the South Pacific and should not be eaten.
