For a challenging run right in Phuket Town, Rang Hill offers a tough 4 km round trip with a great view. Start on Yaowarat Road, between Bangkok Hospital and Vachira Hospital. The steep, switchbacking road climbs through a neighborhood, then is mostly forested before reaching the top of the hill at 2 km. There is a smattering of shops and cafes here, but the highlight is the terrace overlooking the hills and coast of Phuket Town.
Note: No shoulder or sidewalk, but the traffic is manageable. Run opposite traffic — on the RIGHT side of the road.
