Motorbikes are the obvious choice — rentals run about 300 THB per day from shops in town. The roads are good and the main attractions (cave, temple, hot springs) are all within a few kilometres of each other. Bicycles work for the flat stretches closer to town; 100 THB per day. Songthaews can be hired for day trips to the more distant sites like the Pha Daeng National Park hot springs and waterfall.
The town centre and the cave area are about seven kilometres apart — walkable in principle, but most people ride.
