Peak Wilderness sanctuary is a natural reserve in Sri Lanka. It is a tropical rain forest that spreads over a land of 224 square kilometers around the Adam's Peak mountain. The remaining portion of the Peak Wilderness was declared a wildlife sanctuary on October 25, 1940. it possesses unusual geographical formations compared to the other natural reserves of the island. It is one of the best hideouts in Sri Lanka which surrounds evergreen forests at the edge of the reserve. The greater part of the track leading from the base to the summit consists of thousands of steps built in cement or rough stones.
Adam's Peak is a 2,243 m (7,359 ft) tall conical mountain located in central Sri Lanka. It is well known for the Sri Pada, i.e., "sacred footprint", a 1.8 m (5 ft 11 in) rock formation near the summit, which in Buddhist tradition is held to be the footprint of the Buddha, in Hindu tradition that of Hanuman or Shiva and in some Islamic and Christian tradition that of Adam, or that of St. Thomas
The mountain is located in the southern reaches of the Central Highlands in the Ratnapura District and Nuwara Eliya district of the Sabaragamuwa Province and Central Province lying about 40 km northeast of the city of Ratnapura and 32 km southwest of the city of Hatton. The surrounding region is largely forested hills, with no mountain of comparable size nearby. The region along the mountain is a wildlife reserve, housing many species varying from elephants to leopards, and including many endemic species.
Adam's Peak is important as a watershed. The districts to the south and the east of Adam's Peak yield precious stones emeralds, rubies and sapphires, for which the island has been famous, and which earned for its ancient name of Ratnadvipa.
Sri Pada is first mentioned (as `Samanthakuta') in the Deepawamsa, the earliest Pali chronicle, (4th century), and also in the 5th century chronicle Mahawamsa, where it is stated that the Buddha visited the mountain peak. The chronicle Rajavaliya states that the King Valagamba (1st century BCE) had taken refuge in the forests of Adam's Peak against invaders from India, and later returned to Anuradhapura. The Mahawamsa again mentions the visit of King Vijayabahu I (1058–1114) to the mountain. The famous Chinese pilgrim and Buddhist traveler Fa Hien stayed in Sri Lanka in 411–12 CE and mentions Sri Pada although it is not made clear whether he actually visited it.
The Italian merchant Marco Polo in his Travels of 1298 CE noted that Adam's Peak was an important place of pilgrimage but did not mention a footprint in the rock. The Arab traveler Ibn Battuta climbed to the summit of the mountain which he called Sarandīb in 1344 CE. In his description he mentions a stairway and iron stanchions with chains to help the pilgrims.John Davy brother of the noted chemist Sir Humphry Davy visited the peak in 1817. He recorded observing an oversized foot print carved in stone and ornamented with a single margin of brass and studded with gems.
