This day's drive takes you on a direct rural back route (but good roads), passing Khao Luang National Park and Thung Yai district town (amphoe) to Krabi.

A longer route with heavier traffic goes via Thung Song (H403, H41 and H4019) to Thung Yai (N.B. Follow navigation instructions on H4015 closely and check the road numbers as bilingual signs have not been placed along some of the new roads in this area).

Leave Nakhon Sri Thammarat by H4016, which is the first main road to cross the railway south of the station. Take route H4105 at Key Point 12. At KM 20 a right (north) turn goes to the HQ of Khao Luang National Park and a walk that climbs along the sixteen levels of the Kharom Falls.

Keep on H4015 through Ban Chandee (KM 36) where two roads go left. After KM 44, H4015 to Amphoe Chawang bears right. Keep going straight ahead on H4195 (use the KM stones to check you are on the right road - ignore a sign after a few kilometres that indicates H4195 goes right at a T junction) till you reach H41 and Key Point 13.
