Caves
One of my favorite caving adventures is canyon caving. We know of a variety of canyons carved out of limestone by a fairly big flow of water. These are so much fun to climb about in, they are almost prehistoric. The features in these canyons are really beautiful. The caves you can find are pretty cool to visit as well.
The north island has many of these amazing canyons, the island has vast karst areas and this creates these canyons. Sometimes you can start to hike up a stream or creek and before you know it, you are in one of these canyons. This gets me all excited and time seems to stop as you go about exploring.
As you hike up and down the walls of these canyons, you may start to find caves, some large but mostly short caves carved out of the wall by the power of the water as it goes around a corner, then as the canyon cuts its way down into layers of limestone, these caves are left high and dry.
Another wonderful thing about these canyons is the fact that they are hardly ever fished and you could latch onto a nice sized fish for lunch. We have collapsable rods just for these adventures, they fit right in your pack, out of the way of any thick brush that could cause a messy hangup and leaves your hands free climbing.
