Sumatra, Indonesia · 0.2891, 102.9136
Best wind
Wind is not the documented driver; tide timing controls the bore
Season
Largest tides are planned around full-moon windows; exact trip dates must be confirmed locally
Water
Powerful tidal-bore river wave
Experience
Expert tidal-river foiler with an experienced local operator
Hazards
Crocodiles are explicitly reported in the forum discussion, along with remoteness and very large tidal conditions. The post does not document rescue, medical access, river obstructions or a safe fallback line.
Parking & access
The forum describes a remote, arranged package with accommodation and meals but leaves transfers uncertain. Reconfirm airport transfer, river entry, PWC support, recovery and current pricing with a qualified local operator.
“Progression Project forum trip-planning guidance identifies the Bono River tidal bore in Sumatra as a foil destination where a local operator can accompany riders by personal watercraft and where local riders have been seen paddling into the bore. The coordinate is an approximate river-area pin, not a published foil line.”
