R1194 Mae Sarieng - Mae Sam Laep used to be a real work out. The last 15 kms followed the stream & it was 65 stream crossings in 15 kms. It's all paved now & still one beautiful tight steep twisting road from Mae Sarieng to the Salaween River. Mae Sam Laep used to be hive of activity whilst the Karen had control of the land on the Burmese side... Indeed Mae Sarieng was a bit of a boom town in those days. At the same the logs were coming out from Burma by the thousand.
