Labuhan Lalang is the main focus for park visitors as from here they can take a boat across for the snorkeling around Menjangan Island. Fixed-price boat charter is $30 for about 4 hrs, but you can probably arrange to share a 10-seater boat with other tourists. Snorkel and mask hire is $7.
The park staff also offer guided birding walks on the mainland for $7. the pleasant, 2 hr walk takes you southwest along the shore through the back of the Jayaprana temple. Beyond the temple it drops down through scrubby forest to a river and then follows the river back to the road near Sumber Klampok. Birds to see are Buffy Fish owl, Fulvous-chested Rhinomyias and Horsfield’s Babbler. This is the place to look for migrating raptors.
