Penang National Park in Penang
Part of the Penang travel guide — see every topic in All Penang Guides.
Penang National Park, gazetted in 2003 at the north-western tip of the island, covers about twenty-three square kilometres and is the smallest national park in Malaysia. Its size is misleading: within it are lowland dipterocarp rainforest, mangrove, mudflats, several beaches reachable only on foot or by boat, a green turtle nesting site, and a meromictic lake — a body of water whose layers do not mix — which is a genuinely rare phenomenon and the only one of its kind in the country.
The trails
Two main routes leave from the entrance at Teluk Bahang. The eastern trail runs about ninety minutes to Monkey Beach (Teluk Duyung), passing a lighthouse hill; the western trail takes one to two hours to Pantai Kerachut, the turtle beach and the meromictic lake, and is the harder of the two, with steep sections and a canopy walkway near the start. Both are hot, humid and rooty rather than technical. Registration at the ranger station is required and free, and you must sign out on return.
Pantai Kerachut and the lake
Kerachut is the destination worth the effort: a wide beach with a turtle hatchery run by the fisheries department, where green and olive ridley turtles nest and hatchlings are released seasonally. Behind the beach sits the meromictic lake, which forms when seawater is pushed over the sandbar during the wet season and sits beneath the freshwater layer without mixing, creating separate ecological zones. It is seasonal and can be dry, which surprises visitors expecting a permanent lake. The suspension bridge across it is a good photograph.
Wildlife
The park holds long-tailed macaques, dusky leaf monkeys, colugos, monitor lizards, sea otters and a good range of birds including hornbills and white-bellied sea eagles. Macaques at Monkey Beach are habituated and will take food and unattended bags. Offshore, the mudflats and mangroves are important for migratory shorebirds. The park has been the subject of a long-running conservation debate as development pressure has pushed against its boundaries, which is part of why the ranger registration system is taken seriously.
Practicalities
Entry is free; register at the entrance. Boats from the jetty at Teluk Bahang run to Monkey Beach and Kerachut for around 40–80 ringgit per boat each way and are the sensible option if you would rather not walk both directions — walk one way and take a boat back. Bring two litres of water per person, insect repellent, and shoes with grip. Start early; the trails are brutal after ten. There are no shops inside the park and no reliable phone signal on parts of the trails.
