Abbey Caves are completely natural, undeveloped and unguided. Entry is at your own risk.
A circular track of 1300 metres leads you to the three caves: the Organ Cave, Middle Cave and Ivy Cave. All are long and narrow with glow worms and rock formations and stalactites.
The climb down into the caves can be difficult. Once into the caves, it should be level walking but you may need to climb over slippery rocks and will need to travel through very cold water that varies in depth from ankle to thigh to waist height. You may see, and feel, tuna-eels and koura freshwater crayfish in the stream.

Organ cave
The entrance to the Organ Cave requires a short down climb between the cave wall and a large boulder on the right-hand side of the entrance, followed by a short descent to the cave floor. There have been rock falls at the entrance within the last few years.
The Organ Cave only has one entrance/exit so care needs to be taken and always have a contact person. Once in the cave the main passage is high and most people should be able to walk upright most of the way in this approximately 300m cave. There is a section that may have waist deep water. The walls feature stunning stripped patterns and ends in a 17ft domed cavern covered in glowworms.
There are a small number of side passages, these can become tight quite quickly and should only be attempted with the appropriate experience and equipment.
Ivy cave
The Ivy Cave is the last cave along the stream. The descent towards the cave entrance is down a stone ramp which can be slippery. It is best to keep to the left-hand side and take your time. The cave entrance itself requires you to crouch and navigate your way through. It is approximately 200m long and is made up of two main passages. The lowest is a water filled passage with a muddy floor and the water can be chest deep in places. This leads to a downstream exit that pops out in a small ravine. There is no formed track from this exit and can be quite overgrown.
To access the upper level of the cave requires a short climb up a muddy ramp from the lower passage. Care must be taken in this upper passage as there are holes in the passage floor to the passage below. Navigating this upper passage will eventually lead you to the upper dry exit. There is no formed track from this exit.
Middle cave
The Middle Cave is the simplest of the three caves to access and move through. From the sign post, follow the short track to the cave entrance. The entrance itself is wide and is relatively easy to walk down. Once inside the cave floor is flat with ankle deep water. While the Middle Cave has several entrances it is recommended to enter and exit the cave from the main entrance.
