There's a pretty good network of roads east of the 331, not sure of the name of the area but I get to it by going down Soi Siam Country Club, following the road left around Lake Machrapan then turn right onto I think the 3240, across the flyover that's goes over Highway 36, up to the end of 3240 then turn left onto the 331 about 1km then turn right. There's a huge maze of roads there, some great bends and long straights going through farmland, quarry's and the odd village. The roads are very good but sometimes a bit dusty near the quarry's, some of the roads are still being built and not tarmacced yet which are great for flying down on an enduro bike, and there's plenty of dust tracks as well. I tend to go in the afternoon and if I cant find my way out I just head west towards the late afternoon sun and eventually you'll get back to Pattaya.
