I've failed in my attempts via the usual channels, so I'm trying a shout out on here as a last resort!
I'm looking for someone to join me this Weds on an overtide trip into Otter Hole attempting to explore some of the unclimbed avens. Perhaps you're a student or teacher with some time off over Easter and fancy a mid-week trip.
Otter is a somewhat committing trip, so not suitable for novices. But if you're competent and available do get in touch.
