Fence at either end but sections removed so can get through. Path on the East side is rideable for the most part but likely some hike a bike through bogs and over some bigger roots.

A lovely little place to unwind watching the otters bath and play around in the water.
There is also picnic tables, public toilets and a car park here making it an excellent overnight bikepacking location as well.

Nice way to cycle to the Big Water of Fleet Viaduct. Although one of the photo's, suggest there is some tarmac, we didn't found it. It's a really nice gravel …
