Lempuyang Temple, locally referred to as Pura Lempuyang Luhur, is one of Bali’s oldest and most highly regarded temples, on par with Besakih (aka the ‘mother temple’ of Bali). It is also believed to predate the majority of Hindu temples on the island. Definitely a highlight on any travel itinerary for the fit and adventurous, the main temple lies at 1,175m above sea level, up on the peak of the namesake Mount Lempuyang in East Bali. The heights are reachable via a steep staircase of over 1,700 steps, with attractions along the way including several other temples and hordes of grey long-tailed macaques that inhabit the surrounding cool mountain forests.
