This was not an Oxford University expedition. However it carried on the long tradition of OUCC expeditions to the Picos de Europa, and involved some OUCC members and a wide range of cavers from the UK and beyond.
The Expedition's aims were to revisit promising leads in several caves:
- Cave of the Singing Pasteur/Bill’s Cave (27/9) - a possible sump bypass giving a dry route to Sistema Verdelluenga (C4)
- Revisit upstream in Cave of the Witches Eye (2/7, last visited in 1998, 1999, 2000) including - Canals on Mars (drysuits) - Full Moon Rising sump (dive) - high tube in Buy the Ticket, Take the Ride (bolt climb).
- Attempt to connect Tras la Jayada to upstream 2/7 (Holier Than Thou)
