Rarotonga is the largest and most crowded island in the Cook Islands. 
The middle of the island is very different from the coast. It has thick green forests and deep valleys. These valleys were made long ago by the old volcano. Te Manga is the highest peak on the island. It rises 658 meters above the sea. Small streams like the Avatiu and Takuvaine flow down the hills. Because the mountains are so steep, there are no roads through the center. Most people live on the flat land near the beach instead.
People have lived on Rarotonga for a very long time. Polynesian groups arrived there around the year 1000. 
The island has many interesting places to see and do. You can walk on white sandy beaches or go snorkeling in the lagoon. The lagoon is protected by a shallow reef. 
Traveling around the island is quite easy for visitors. A main road called Ara Tapu circles the entire coast. There is also an ancient road called Ara Metua. This old road was built in the 11th century using stone slabs. There are only two bus routes that go around the island. One bus goes clockwise and the other goes anti-clockwise. Many people also use taxis to get around the different districts. The capital city, Avarua, is the main hub for everything.
Rarotonga is the largest and most populous island in the Cook Islands. 
The island's geography is shaped by ancient volcanic activity. Rarotonga is the summit of an extinct volcano from the Pliocene or Pleistocene eras. This volcano rose from the seafloor between 2.3 and 1.6 million years ago. A second stage of volcanism occurred between 1.4 and 1.1 million years ago. Scientists believe it may have formed from a short-lived Rarotonga hotspot. The island's core consists of densely forested hills and deep valleys. These features are the eroded remnants of the original volcanic cone. Te Manga is the highest peak on the island and the entire country. 
Water moves through the island in a radial pattern. Many streams drain the central hills toward the coast. These include the Avatiu Stream and the Takuvaine Stream. The hills are surrounded by a low coastal plain. This plain contains beaches, lowland swamps, and alluvial deposits. A storm ridge also sits along this coastal area. A fringing reef surrounds the entire island. This reef varies in width and is quite shallow. The maximum depth of the reef is only 2 meters. There are several passages in the reef, such as those at Avarua and Ngatangiia. Beyond the reef crest, the outer slope drops steeply into deep water. The Muri Lagoon in the southeast is the widest part of the lagoon. This area contains four small islets, or motu. These islets are named Motutapu, Oneroa, Koromiri, and Taakoka.
Human history on Rarotonga began many centuries ago. Evidence shows Polynesian people inhabited the island around AD 1000. Oral traditions mention several specific groups settling the island. These include Ata-i-te-kura and Apopo-te-akatinatina. In 1250, Tangi'ia Nui from Tahiti and Karika from Samoa arrived. Early settlers maintained trading contacts with the Austral Islands and Samoa. They imported basalt to make local adze heads. Most settlement cargo, including crops and animals, originated in Southeast Asia. This included chickens, pigs, dogs, and several species of lizards. 
European contact changed the island's history significantly. Captain John Dibbs is credited as the European discoverer in 1823. He was transporting the missionary Reverend John Williams on the ship Endeavour. By 1830, much of the island had converted to Christianity. Between 1830 and 1850, the island was a stop for whalers. In 1888, the island became a British protectorate. New Zealand later annexed the island in 1901. The citrus industry became a major part of the economy. Oranges were introduced by the Bounty mutineers. A canning factory opened in 1961 to export juice. However, this industry collapsed in the 1980s due to changes in market access.
The island is divided into specific traditional and administrative areas. It is traditionally split into three tribal districts called vaka. These are Te Au O Tonga in the north, Takitumu in the east and south, and Puaikura in the west. 

Nature conservation is a vital part of island life. The Takitumu Conservation Area protects native plants and birds in the southeast. This area is recognized as an Important Bird Area by BirdLife International. It provides a home for the vulnerable kakerori, also known as the Rarotonga monarch. Other protected birds include the Rarotonga fruit dove and the Rarotonga starling. Visitors can enjoy many activities like snorkeling and hiking. Some people even visit the sea wall to watch planes land at the airport. The island remains a place of deep natural and cultural significance.
