One of the largest reservoirs in Phuket is located in the Katu area. There is an asphalt road around the reservoir, where many people run, ride bicycles or just walk, if they are lazy, then you can also ride a bike (about 6-7 km circle). The place is quite quiet, with great views of the lake, there are several cafes and shops for relaxation. It's ideal if you want to relax in nature and avoid the crowds, although the place has been getting more popular lately.
