Kilim Karst Geoforest Park

Kilim Karst Geoforest Park is one of three geoforest parks within the Langkawi UNESCO Global Geopark in northeastern Langkawi, Kedah. It covers the Kilim River basin with extensive mangrove forests, limestone karst formations, caves and estuarine waterways. Notable for its 500-million-year-old karst landscape, diverse mangrove ecosystem and wildlife, it is accessed primarily by boat tours from Kilim Jetty.

Visitors can expect a river and coastal boat tour through mangrove-lined waterways surrounded by towering limestone karst towers and cliffs. The tour typically includes stops at caves such as Gua Kelawar (Bat Cave) and Gua Buaya (Crocodile Cave), eagle watching areas, floating fish farms, fishing villages, and beaches. The environment is natural and estuarine with dense mangroves, mudflats, and opportunities to see birds, macaques, monitor lizards and marine life. Exploration is mainly by boat with short walks inside caves and at jetties.

Part of the Langkawi UNESCO Global Geopark, the first UNESCO Global Geopark in Southeast Asia endorsed in 2007. The karst landscape dates back approximately 500 million years to the Cambrian period, representing some of the oldest rock formations in Malaysia and showcasing significant geological evolution.

The area reflects traditional coastal fishing culture with floating fish farms and fishing villages that depend on mangrove resources. The mangroves have long been valued by local communities for fisheries, timber and coastal protection.
