Not too far away from Bangkok and a great place to ride is the jungle single track trail of Tam Pratoon, originally used as an off road trail for motorcross bikes it is an ideal single track trail for mountain biking and ridden in reverse this is one thrilling track.
This trail has now dissapeared and can't be used but just 500 meters away there is a the Phuthamonthon new trail.
The trail is 7 km of flat single track but don't let this put you off. The trail which is well looked after is purpose built for xc mountain biking and is a nice fast track. It consists of swich backs and rises and dips in places with small burms that weave in and out of the trees and small plank bridges that connects the track over small becks. The trail is a great introduction to single track mountain biking and a good bit of exersize, often used for training by seasoned semi pros. This trail is great fun and only about 30 mins to 1hour drive (depending on the traffic of course) from the center of Bangkok.
The park is full of wild life including giant monitor lizards and terrapins, However don't be afraid of giant monitors they often lay basking on the track but are used to the MTB traffic and will soon move when they see you coming.
The trail can be quite difficult to find so we have added a map below. Once you found the start point the trail is easy to follow and its marked every so often with signs showing to distance.
To find the trail go to the far end of the park (the opposite side of the entrances). There is a straight river/canal running parallel to the road the start is near the road in the trees, look for a small sign nailed to a tree showing the distance.
