Mostly rideable downhill on a gravel bike if you're confident, but fairly boggy at the top. Uphill would be significant amounts of hike-a-bike for all but the most capable!

The downhill stretch of the road is now almost completely washed away. So there is no descent to be had on the bike. If you're on a full suspension bike it might just be doable but anything else - or bikepacking - you'll be walking.

Running water for the toilets but no taps so no bottle refill. Understand there is a tap at the bunkhouse to the north.

A very rocky steep descent, be wary on gravel bikes

Quite a deep ford with some slippery rocks. Take care when crossing by bike

Seems to be a victim of Arwen + 4x4s with big gullies that could end your career and really rough slate undressed surface. The initial ramp southward is just about unrideable. I'd say this is mountain bike only at this point, though an unloaded gravel bike might stand a chance. Great once you reach the top if heading south. See the last photos on this highlight for the condition in June 24.
