💡 Good to know
- This Upper Karakoram journey is offered only for the five complete months from May through September. Road access is never guaranteed: rain, landslides, rockfall, flooding or an authority restriction can close the highway even during the supported season.
- This journey is unavailable from October through April. The discovery sources describe a season ending around mid-October, but the planner cannot represent a partial-month boundary honestly, so it does not advertise October; choose May through September and recheck current road and weather advice before travel.
