Green Valley G.C. on Bangna Trad Hgwy south of the city has an awesome practice ground.  It is only about 30 mins from anywhere in Bkk.   Make a U turn at klm marker 16 and go back about 2 klm’s on the left.  It is on the same soi as ‘American School of Bangkok’ and well sign posted.

Here we have a range facing northish so no sun on the mats or in your eyes.  Hitting from grass is available and the practice balls are inexpensive.  There is a good putting/chipping/lob pitching green at the range and also a sand bunker to work both greenside and fairway bunker shots.

Friendly staff, cheap range balls, facility to work every golf shot and not far from the city makes this range excellent for a 1/2 or full days golf training.   It is also an excellent golf course and has a good restaurant.
