The Andirilena Cave is a cave located 4 km (2.5 mi) from Udugama, in the Galle District of Sri Lanka (25 km (16 mi) from Belihuloya towards Colombo on the Balangoda–Colombo road). The cave system begins from a 4 ft (1.2 m) opening, before splitting into two main channels (and more smaller caves), before joining back after approximately 500 m (1,600 ft) in.
