In reply to GoneFishing111:
The Valley Entrance cave with the barrel entry is part of a huge cave system in West Kingsdale with passages extending over 9 km, with many flooded passages. Most novice parties venture in as far as the West Kingsdale Master Cave.
You would have come out the same way as you went in, as trips through from different entrances would be beyond the novice group trip.
Further up the valley is the Yordas Cave which was used as a former show cave in years gone by. You can walk straight into a huge chamber approx 60 m long and 15 m wide so maybe you popped in here after having a look in valley entrance.
