Number 9 Bend located at 17.363, 101.0516
The climb out of the valley from Na Mala on Route 2113 inadequately heralds what is further ahead. Phu Khao Ngam Viewpoint (aka Number 9) is an amazing bit of road engineering. Viewed from the right location the road forms the shape of the numeral 9. Plenty of room to park and because of the geography most vehicles are moving fairly slow so it safe to get to the Viewpoint.

- An amazing piece of road engineering switches back on itself to form the shape of the numeral 9. See this on Route 2113, Na Haeo, Loei Province.
Number 33 Bend located at 16.5457, 98.5990.
The easiest way to get to Number 33 Bend is to take Route 1090 out of Mae Sot for 16 kilometres south to Huai Mai Pan. Turn west just before the PTT Station onto Rural Road 4014. Follow this road for approximately four kilometres to Ban Mae Kon Ken village. Turn left (south) and follow the road for about five kilometres to the parking area at the top of the slope of the 33 Curve Road to fully appreciate the view.
