We absolutely loved this trip. We were just expecting a run of the mill caves and standing in the dark to see the glow woms. This trip is so much more. just the adventure of walking on a series of steel grate platforms and steps above a clear torent stream over waterfalls, eddies and minature gorges was worth it, then to hop on a boat and be pulled through a mini lake in the dark and quite to view the magical glow worms was absolutely fantastic. Highly recommend this if you can book the very popular trip.
