751 has green but there must be more

Oct 17, 2006
Thanks to previous recommendations I went to CENTRAL and bought Michelin map 751 on Thailand. Beautiful scenery along the roads is marked by green lines. But because of the large scale 1cm = 13,5 km only few roads can get this quality mark. The Globetrotter maps on Northern Thailand have more detail, 1 cm = 4,5 km but no mark for nice trips.
Samesame for Samui ,Pha ngnan and Southern Thailand, no marks. Very unhelpful for planning a succesful trip. As we know roads here can be awfully boring with shack after shack lining the roads for miles on end.
Are there better detail maps for planning a beautiful trip around ? Or have I to resign to trail and error?
