About This Tour
This is an authentic experience exploring an abandoned mine, with various optional challenges; involving climbing, an abseil, a tyrolean (short zipline) and a short boat crossing. There isn't anything artificial about this trip with the addition of safety anchors being the only changes you'll find in the mine, where necessary, as such, it is most similar to caving with the only lights being those on your headtorches (provided). This is the perfect family adventure, Stag/Hen do activity and couple challenge.
