Rawhiti Cave facts for kids
Rawhiti Cave, also known as Manson Cave, is a huge limestone cave found in the Dry Creek Valley. It's about 7 kilometers southeast of Tākaka on the South Island of New Zealand. While some maps call it Manson Cave, most people and official information use the name Rawhiti Cave.
The cave's entrance is one of the biggest in New Zealand. It's about 40 meters wide and up to 20 meters tall! Inside, the ceiling is covered with many stalactites, which are rock formations that hang down like icicles. A short path leads visitors to a special viewing platform inside the cave.

Amazing Plants in the Cave
Rawhiti Cave is special because of the many different plants that grow near its entrance. This area is called the "twilight zone" because it gets some sunlight.
How Plants Shape the Cave
Over a long time, plants growing on the cave's rock formations make them grow towards the light. This happens because new rock material, called calcium carbonate, builds up on top of the plants. This amazing process is called phytokarst. You can see it clearly on the large stalactites near the entrance. They curve outwards because moss and ferns grow heavily on the sides that get sunlight.
The cave is mostly untouched and natural. Delicate ferns and mosses grow on the sloping floor. Even some stalagmites (rock formations that grow up from the floor) are shaped by plants, also growing towards the light.
Red Algae in Winter
During the colder winter months, the sun's rays can reach the very back wall of the cave. This allows tiny plants called algae to grow there. These algae cover the walls in beautiful shades of red. They are able to survive with very little light, just enough for them to make their own food.
History and Visiting the Cave
Rawhiti Cave was formed about one million years ago. The original roof of the cave collapsed a long time ago, creating the huge, self-supporting dome you see today.
Early Tours and New Ownership
In the early 1900s, a man named Darcy Manson, whose family owned the land, made a path to the cave. He started giving tours until the late 1920s. He named the cave Rawhiti, which means "sunrise" in the Māori language. He chose this name because the winter sun shines all the way to the back of the cave.
From 1955 to 2000, the Baird family owned the cave and offered daily tours. In 2000, the cave became owned by Heritage New Zealand. Now, the Department of Conservation NZ manages the area, which includes the Dry River Scenic Reserve and Rawhiti Caves Scenic Reserve.
Visiting Rawhiti Cave
To get to Rawhiti Cave, you start at a parking area on private farmland. You'll walk for about 30 minutes into the Dry River valley. After that, there's a 30-minute uphill zigzag path that leads to the cave entrance. The viewing platform inside the cave is well-lit, so you won't need a flashlight.
Rawhiti Cave is one of the few caves like it that you can visit for free. Because the cave environment is very fragile, visitors are asked to stay on the path to help protect it.
