Tampaksiring is an inland district in Gianyar regency, north-east of Ubud, best known for the Tirta Empul spring temple and the presidential palace above it. The land is river valley and rice terrace, at 400–700 metres, noticeably cooler than the coast, and it is roughly 75 minutes from the airport.
Plots here are agricultural in character and frequently come out of long-held family ownership, which changes what has to be checked. Inherited land can have more owners on paper than the person selling it, and a subak irrigation easement or a river-valley setback can cut through a parcel that looks unencumbered on a map.
What a Bali land certificate actually proves covers the first problem, and the structures a foreigner may lawfully hold covers how land like this can be held at all.
