Kalasin , the land of Pong Lang music, is an ancient city with many interesting historical sites. It is the site of the ancient city of Fa Daet Song Yang and one of the largest concentrations of dinosaur fossils in northeastern Thailand. In additon, the province is well known for their silk cloth with the uniquely beautiful and intricate'phrae wa' designs, that can only be found here. The fabrics are hand-woven on traditional looms after undergoing many delicate 'mudmee' dying techniques. Kalasin has an area of 6,946 square kilometres.

The highly revered Phra Buddha Rup Ong Dum Buddha image is housed at the provincial principal temple of Wat Klang. The base of the image is inscribed with ancient Thai writings. Whenever there is a drought, the townspeople would carry the sacred image in an elaborate procession to request rain.

Several Buddha images are located in beautiful natural sites outside the city. On a cliff outside of town are 2 Dvaravati-style Buddha images, the Phra Buddha Satarn Phu Bor. The first image is situated at the foot of the Bor Mountain, near the ascending path, while the other image is at the top. The Buddha image of Phra Buddha Saiyad is etched in the rock wall underneath a cliff in Wat Buddha Mimitr. The Buddha Sathan Phu Singh (Singh Hill Religious Site) located at the top of Phu Singh Hill contains the large Buddha image of Phra Pome Phumipalo.

Artifacts found at the Fah Dat Song Yang City indicate the town was inhabited during prehistoric times and prospered during the Dvaravati period (6th-11th centuries). The ancient settlement was surrounded by two layers of moats and the only surviving, distinguishable remain is the Phra That Yakhu (Yaku Chedi).

Dinosaur fossils were recently found at the Phu Kum Khao Dinosaur Fossils Area , the largest area of its kind in Thailand, making it a popular tourist attraction. Many fossils were discovered among the rocky ground surface which experts have determined to be mainly the Soropods, a large herbivore with a long neck that existed about 130 million years ago

Situated east of the dam, the Lam Pao Wildlife Park (Sa-on Park) is an open zoo national park where wild animals roam about in their natural habitats, particularly the red bulls, which is used as the park's symbol.

Of particular interest at Kaeng Ka-am Waterfall are the rapid that passes through a long, rocky passage and a spacious, rocky plateau suitable for relaxation.

Another fall in this vicinity is the Pha Savoey Waterfall. Originally called Pha Rang Raeng, the name was changed in 1954 when H.M. the King and the Queen stopped for lunch here while passing the area. The name was then changed to Pha Savoey (Royal Dining Cliff). The Pha Savoey is situated on a high, steep cliff with a deep gorge down below, offering a good view of the surrounding areas.

The Fah Mue Daeng (Red Palm Prints) Cave is located on the Phu Pha Phueng mountain. The prehistoric paintings of as many as 174 red palms were discovered and received much public attention during 1973 and 1980, being the largest number of red palm paintings found in the Kingdom of Thailand. Such paintings are regarded as important historical evidences in the search for lost accounts.

The area of Phu Khao Cave was formerly an important religious place but presently, only the small temple of Wat Buddha Nimit, housing the Phu Khao Reclining Buddha, is of any significance. This Reclining Buddha is different from other ones because it lies on the left sideand because there is no finial. Legend says that this Reclining Buddha was made during the year 1,300-1,500. Generally revered by villagers, a fair held to pay homage to the image takes place during the Songkran Festival every year.

The Ban Phon Prae Wa Weaving Group produces fine, delicate designs on predominantly red silk fabrics, a specific art and craftmanship of Phuthai tribal people. H.M. the Queen Sirikit has been promoting this type of fabric and it is currently very popular.
