The watermill and Bridge at Kouiassa belong to the community of Kalarites, at an altitude of 807m, in the Chroussias river valley. The site is accessible along the route to Kalarites. The trip is about 15 minutes on foot. After the iron bridge before reaching Kalarites, there is a sign on the left pointing to the stone bridge of Kouiassa and the old stone watermill. The footpath starts at the steps on the right, and the stairs to Kalarites will bring you to the quaint village. The route continues straight on and soon you’ll see ahead the beautiful watermill and the impressive waterfall; they start from the springs below Kalarites and fall into the Chroussias river. The location is one of rare beauty and unique sounds of nature.

The name Kouiassa means ‘shady location’. The bridge has a single arch spanning 5.40m, and up to 18m high. On the trunk of one of the bridge-supports there is a smaller arch that lightens the construction (relieving arch) and allows the water to flow faster in case of flooding.

The watermill is hidden in the forest and looks like a fairy tale background. At the site of the watermill, from the summer months to November, a traditional coffee-shop operates that also serves meals. The café serves home-made lemonade and hand-make ekmek, a sweet made with shredded wheat and patisserie cream.

There are picnic facilities on the site and bold visitors refresh themselves in the crystal- clean fresh waters of the Kalaritikos river. The footpath is of moderate difficulty. It is 1km long and at some points there are stone-steps, and it takes about 15-20 minutes to cover it. The bridge is about 6-7 minutes’ walk from the watermill.
