Chumphon National Park

Chumphon National Park is part of a much larger Chumphon Archipelago that includes famous islands of Koh Samui, Koh Phangan, and Koh Tao. The province of Chumphon is officially called “Gate to Thailand’s South,” while Chumphon Marine Park welcomes you to the southern islands of Thailand. Announced as a National Park in 1989, Chumphon National Park spans an area of 317 square kilometers covering 100 km of beaches and 40 islands in the Gulf of Thailand.

The most popular islands of Chumphon National Park include Koh Ngam Yai, Koh Ngam Noi, Koh Samed, Koh Mattra, Koh Lawa, Koh Kalok, Koh Langka Jew, Koh Phitak, and Koh Maphrao. Every year, thousands of people visit to scuba dive and snorkel in its greenish-blue sea and relax on the white-sand beaches. Chumphon National Park is a hidden jewel of scuba diving in the Gulf of Thailand with spectacular reefs and unspoiled waters attracting whale sharks. It is surprising that international travelers widely neglect this pristine region. Do you want to be among them?

Ranped and Rangai islands are small islands located in Tambon Paklong, Amphoe Pathiu, Chumphon province. They are limestone islands with no human residents although they are home for a lot of swallows and seagulls. 

Ranped and Rangai islands are not yet filled with a lot of divers so the dive sites are quite environmentally preserved. They are famous for their colorful sea anemones which are so abundant and make the site look similar to a field full of flowers. Divers also usually enjoy plentiful corals, heart-shape underwater cave (Rangai island), schools of fish with various sizes and types, and most importantly swimming with whale sharks that are often spotted around the dive sites.

The deepest parts of these dive sites are around 30 meters from the sea level.

Koh Tao

Koh Tao is an island in Thailand. Restaurants, nightspots and dive shops cluster in Mae Haad Beach and near Sai Ri Beach. Villas dot palm-fringed beaches such as Chalok Baan Kao Bay, on the south coast. In the northwest, Koh Nang Yuan is a group of islets with hilltop views. Ko Tao is known for its tropical coral reefs, with species including whale sharks and rays. Hawksbill and green turtles gather here to breed.

Sail Rock

Sail Rock, or Parus Rock is a natural sandstone monolith of late located on the shore of the Black Sea, in Krasnodar KraiRussia. It resembles the outline of a ship's sail, hence its name.

The monolith lies 17 km to the southeast of Gelendzhik, near the village of Praskoveyevka (which is about 500 m from the coast) and the farmstead of Dzhankhot (approximately twice that distance from the coast). Sail Rock has a sheer vertical slope confronting the shore of the sea, isolated from the mass of basic rock by geological forces. It is more than three-fourths revealed by the tide and lies perpendicular to the coast. What is most remarkable about this landmark is its proportions. While the cliff is only a little more than one metre thick, its height is about 25 m and its length about 20. Thus, the form of the cliff is described as resembling the outline of a quadrangular sail.

An opening of unclear origin is located in the sail, approximatively 2.5 metres above the ground. Many guides state that the formation was a defence against mountain artillery during the Caucasian War. However, this version of the origin of the opening is under some doubt. In 1903, S. Vasyukov, who was investigating the Black Sea coast, wrote after the inspection of the cliff that it was shot from a battleship by seamen, they released 4 projectiles, but the wall remained firm, although the traces are noticeable, but they nowhere opened the rock.

The appearance of this unique formation is explained by the pounding of the sea on the land (erosion), as well as the different strengths of its constituent rocks.

Sail Rock's status as a natural monument was declared November 24, 1971 by the administration of Gelendzhik. Protection of the rock was entrusted to the Divnomorskiy rural council. The surrounding beach and its environs are a place for outdoor leisure and recreation, including nearby health resorts. President Putin has a large estate about 1.5 miles down the coast.
