Ngerchol occupies the northern part of the island on the west side of Bloody Nose Ridge.

On the islands, traditional gardens would have been located in areas where sufficient soil had accumulated in low lying pockets and marshes.

[2] First sighting of Peleliu, Babeldaob, and Koror recorded by Westerners was by the Spanish expedition of Ruy López de Villalobos at the end of January 1543.

[3] In November and December 1710 these three islands were again visited and explored by the Spanish missionary expedition commanded by Sargento Mayor Francisco Padilla on board of the patache Santísima Trinidad.

The ruins of many of the military installations of the era, such as the airstrip, are still intact, and shipwrecks from the battle remain visible underwater just off the coast.

Located at the southern tip of the lagoon which encircles the main group of islands, Beliliou is surrounded by a thick fringe of mangrove forest comprising more than a quarter of its total area.

On the island's west side is a steep spine named Bloody Nose Ridge during the Battle for Peleliu in World War II - rising to an elevation of 75 metres (246 ft).

A second raised area, Rois ra Sang and Roischemiangel, rises to elevations of just over 50 m at the northern tip of the island.

As many as 10,000 Japanese defenders dug into the natural caves and fissures of the coralline limestone formations, reinforcing these positions with concrete bunkers.

So well established were the Japanese defenders that they withstood a massive naval bombardment and met the American invasion force at nearly full strength on September 5, 1944.

Including the capital, there are a total of four villages: Today, the major concentration of people live in Kloulklubed near the northern tip of the island.

[11] The sandflats, mangroves, seagrass beds and islets just off the northern end of Peleliu provide feeding and roosting habitat for various wader species, as well as being home to megapodes.

The site is an IBA for the megapodes, Far Eastern curlews, ruddy turnstones, great knots, red-necked stints, and grey-tailed tattlers.

The landing strips were unimproved, but still served for the daily flight from the Airai airport by a single engine plane.

[2] In any event, in mid-2024 after months of work, U.S. Marine engineers reactivated the Peleliu airfield to enhance US military capability in the Pacific region.

The main road lies on the west side of Bloody Nose Ridge and extends from Kloulklubed to the landing strip.
