I have a trip planned to the Gouffre Berger this summer so am going to be more caving focussed for the first part of the summer, this meant despite the glorious spring weather a reasonable team had been assembled to tackle a Simpsons/Swinsto [glossary “a caving trip where two teams descend different entrances to the same cave system, pass each other underground, and exit the system via the other team’s route (de-rigging any equipment left by that team on route)”]exchange[/glossary]. I went in Simpsons & out Swinsto. Both of these trips are more often done as pull downs with an exit via valley entrance. This was the first time I had done the exchange though I had once previuosly bounced Simpsons. Doing it as an exchange in my opionion makes for a much more enjoyable trip taking around 6 hours, and felt like a proper caving trip. It also means an accidental decent of Bobs Pit (which we didn’t) would be less serious, apparently it goes at VS 4c. Exiting via Swinsto is suprisingly damp with a couple of interesting climb outs. Overall a fun trip.
