Because of its importance as one of the finest examples of decorated caverns in Europe, access is restricted and is managed by the Royal Forest of Dean Caving Club on behalf of the landowner.

After a short crawl with few squeezes the passage opens out to a 'beach' where the tidal sump blocks access.

At low tide this sump drains quickly and noisily, becoming passable as a 'duck' beneath a 'figure 8' double opening.

[2] Continuing past the sump, a fairly linear route leads along the active streamway, eventually reaching a pool in which many choose to remove some of the thick estuarine mud that could otherwise sully the delicate formations.

All trips are run with wardens from the Royal Forest of Dean Caving Club, who are there to both guide and control impact on the area.
