What Are Swallow Holes?
This amazing place has more than fifteen swallow holes. These are like natural drains in the ground. They are unique because they are the only ones found in chalk rock that stay open all the time. When it rains, water flows into these holes and disappears underground.
The River's Beginning
The water that goes into these sinkholes doesn't just vanish. It actually becomes the start of the River Colne! This shows how important these natural features are to the local water system.
Special Plants and Habitats
Next to the swallow holes, you'll find a swampy area. This swamp is filled with willow trees and is known as a willow carr. It's a very important habitat for many different plants and animals. In the deeper parts of the water, you can see reed sweet-grass growing.
Other Natural Areas
Besides the swamps, Water End Swallow Holes also has areas of woodland and open grassland. These different types of habitats make the site a home for a wide variety of wildlife.
