Salawin National Park covers an area of 721 square kilometers.
It is situated on the banks of Salawin River (also known as Salween River) right on the Thai Myanmar border.
The park is 164 kilometers south of Mae Hong Son.
Salawin River originates from Tibet before flowing through China, Thailand and Myanmar, covering a distance of more than 3,000 kilometers.
Those who want to take a boat ride along the river have to contact the park headquarters.
In addition, if you are planning to stay in park, you can get accommodation and other facilities arranged through the headquarters.
In order to reach the park headquarters, you need to take Route 1194 from Mae Sariang district for about 4 kilometers and then travel on a dirt road for another 4 kilometers.
The park is very well kept and it is the water source for Yuam, Kong Ka, Mae Ngae and Han Rivers.
The park is home to many different kinds of plants and trees, the most outstanding being the Xylia xylocarpa or the red teak.
The park is also home to a variety of wildlife like antelopes, deer, barking deer, tigers, boars, bears, squirrels, chipmunks, gibbons, palm civets and a host of birds.
Salawin National Park has three different seasons.
It is summer from March to May; the rainy season sets in from June through October; and winter is from November to February.
If you are interested in a boat trip along the river, the best time is from March to April when the water level is low and this allows many sandy beaches to appear where you can stop for a quick dip to escape from the sun.
The scenery along the river is captivating with small hamlets dotting the forest and mountains.
You can camp on the sandy beach that is right in front of the headquarters of the park if you are looking for a more adventurous trip.
