Frog Hill

Frog Hill, also known as Bukit Katak, is an abandoned quarry site in Kampung Guar Petai, Tasek Gelugor, Seberang Perai Utara, Penang, Malaysia. The site features flooded quarry pits with striking turquoise-blue water contrasted against reddish-brown earth walls and surrounding oil palm plantations. Once an active mining and quarry area, the flooded pits have become a popular informal natural attraction known for scenic photography and short hikes.

Visitors can expect a short walk through an oil palm plantation on dirt and laterite tracks leading to an elevated viewpoint over abandoned quarry pits. The main view is of two flooded pits with vivid turquoise water enclosed by steep reddish-brown earth walls and sparse vegetation. There are no built structures, shops or formal viewpoints; the area is open and exposed with informal trails around the rim for photography and sightseeing.

Former quarry site in Seberang Perai Utara where extraction activities ceased and abandoned pits filled with rainwater, creating deep turquoise lakes surrounded by exposed laterite walls. The flooded quarry has since become an informal visitor attraction.
