Golden baked sandstone cliffs serve as bastions of Bako National Park. The seaside cliffs hold many intriguing bouldering problems and short rock routes best top-roped (due to soft rock and poor pro). Best time is low tide and in the morning shade or evening low sun. The area holds many sandstone outcrops that have not yet seen climbers shoes. Go explore while visiting the beautiful and diverse park, where you can see pit vipers, bearded pigs, proboscis monkeys along the coast and plenty of langurs and macaques.
Access to the park is almost exclusively done by boat. It is a 30 minute bus ride from Kuching to the landing, and easily arranged in Kuching as buses leave every hour for the park. A 25 minute boat ride takes you to a pier at high tide or on the beach at low tide. The rocks are easily seen on the right side of the beach. Hiring a boat will get you around the coast to untapped rock outcrops as well.
Accomodation is comfortable bungalow hostels or private rooms or a full bungalow. Its very cheap, but you must book ahead in Kuching as it gets full on weekends. Go to the downtown tourist booking office/forestry department. Good Luck and Bon Voyage!
The park may be inacessable in the rainy season due to high seas. Check ahead and have plastic over your backpack/climbing stuff as it will get wet at any time of year in the small boats making the jaunt out to the peninsula. Its like Krabi where you have to take a boat around the coast. The park is secluded and quiet, no cars either!
