SayanWhy Visit Sayan?
Sayan lies deep in the riverine interior of central Kalimantan, where rivers serve as the main highways. Travelling by longboat along the waterways is the classic way to reach and explore the area, and river levels are lowest and navigation easiest in the dry season.
The surrounding equatorial rainforest is the region’s greatest draw. In the drier months, when animals gather near shrinking watercourses, wildlife watching can be rewarding, and forest walks lead into some of Borneo’s least-visited jungle.
The inland communities of the Kalimantan interior are known for their longhouse traditions. River lodges and simple home-stays offer a glimpse of local life well off the usual tourist trail.
This is a genuinely remote, riverine corner of inland Borneo with limited tourist infrastructure, suited to adventurous travellers prepared for basic facilities and slow, weather-dependent travel.
About Sayan
Sayan sits on a lush ridge in the Ubud valley of central Bali, above the fast-flowing waters of the Ayung River. Once a sleepy string of villages just west of Ubud, it has become known for the luxury resorts perched along the valley rim, drawn here by the sweeping views over terraced rice fields and dense river-gorge jungle.
The setting is the main draw. The Ayung River below is Bali’s most popular white-water rafting run, threading past jungle walls, small waterfalls and carved cliff reliefs. Along the ridge, spa retreats and open-air restaurants make the most of the cool valley air and the panorama across the gorge.
Sayan works well as a quiet base close to the action. It is only a short drive into Ubud for its markets, temples and monkey forest, while walking trails drop down through the rice terraces to the river and back up the far side. Longer day trips reach the temples and villages of the surrounding Gianyar regency.
