The easiest approach to the entrance now (2003) appears to be from the Arredondo side of the hill, using the track that winds up between the Vallina entrances. Driving to the left and leaving the car where the track gets really rough and steep allows a reasonable walk through an obvious col (probably at site 1140) and a walk down round the hillside to "Vaccinator".
A wooden beam belay for a handline provides help down an awkward T-shaped, descending passage. A great deal of gardening has been done at the head of the pitch, but there is still loose material in the "floor".
The first pitch drops 3m to a rebelay and then 17m to a ledge. An inlet enters here, the Air Raid Shelter, providing protection from rocks knocked from above. (It may link to site 1130). A traverse line leads to the head of the second, 15m pitch. At the far end of the chamber a narrow stream passage carries on down to a 4m climb where a ladder is useful for the return up the tight slot. Beyond, an 8m pitch is the route downward and, after wriggling along a rift to the right, a drop was undescended until 2003 when a 14m pitch landed at a hole that required enlarging to an 8m pitch and no way on.
The 8m pitch on the main route down drops onto boulders (care!) followed by the 16m Rum Doodle pitch. Below, a corner leads to a tight slot where a 2m ladder is useful for the return. The cave continues downward through Brugal Pot (10m and tight at the top), p7, p6 the Do-Rum-Rum (p20).
All pitches from Rum Doodle down are on single bolts - second bolts are needed. A tight rift is then followed down two climbs to join a fossil passage, the Jumping Mouse Passage. To the right a climb up gets too tight after 4m. A sandy dig draughts well and has been pushed for about 5m where it continues low as far as can be seen. To the left a small passage on the right wall has been baled and drained to form a passable duck, pushed for approximately 10m to where a false floor prevents further progress. Hose pipe was taken down in 2003 in a vain attempt to drain the pool. At the end of Jumping Mouse a too-tight tube takes the small stream and a strong draught.
Digs to the right end in small chambers. Jumping Mouse Passage contains a calcite floor very similar to that in the Rio Blanco in Cueva Vallina, which it may feed.
