verified Ungraded High flood risk Log pod Mangartom, Soča Valley

A 5 hour vertical-water descent in the Mangart drainage above Log pod Mangartom, more committing than nearby Fratarica.

Sister canyon to Fratarica geographically but a different character: shuttle required, the IV exit grade flags it as committing once past the upper rappels. The trailhead area is shared with several other Mangart-area descents; confirm route with a recent trip report before going in.

Elevation~1312 ft loss
Time5-5.5 hr (15 min approach, 5 hr descent, 5 min exit)
TechnicalBig limestone descent in the Mangart drainage. Ropewiki rates 4C III (v4a3 IV). Longest rappel 164 ft (50 m). The aquatic grade is moderate but the exit grade IV flags committing terrain with limited bail options. Shuttle of 5 km required.
SeasonSummer primary, water-dependent. Cold all year, dry suit useful early or late season.
Flood riskHigh. Mangart-drainage catchment, sustained vertical descent with no realistic escape after the first major rappel.
Vehicle access2WD with a shuttle setup. Paved road through Log pod Mangartom serves both trailhead and exit.
CrowdSolitude likely; the v4a3 IV grade and 5 hour descent keep traffic minimal.
