Most climbing would be in the Knuckles Mountain Range. Other possible places would be The Ella Adventure Park, Habarana, Sigiriya, Polonnaruwa, Babarkanda, Horton Plains and Buttala. Thulhiriya is apparently bolted.
For the moment, however, Sri Lanka’s only international airport is Bandaranaike International Airport (www.airport.lk) at Katunayake, 30km north of Colombo. There are 24-hour moneychanging facilities in the arrivals and departures halls as well as ATMs. Compared to years past, the airport is much more orderly now and the throngs of touts that once greeted passengers are gone. Transit passengers and those checking in early should note, however, that the terminals remain quite spartan in terms of amenities. Sri Lanka is well served by major Asian carriers, including Malaysian budget favourite Air Asia. Service from India is competitive between several carriers. Many visitors combine a visit to Sri Lanka with the Maldives. Sri Lankan Airlines and Emirates fly between Colombo and Malé. Australia & New Zealand Connections are on Asian carriers such as Singapore Airlines and Thai Airways. Using Emirates requires major back-tracking. Sri Lankan Airlines links Colombo nonstop with Frankfurt, London, Paris and Rome. But nonstop service by a European airline remains a holy grail of Sri Lankan tourism. Connecting through on a Middle Eastern carrier such as Emirates, Etihad Airways, Kuwait Airways and Qatar Airways is common. You’re literally going halfway around the world from Canada and the USA; from the west coast connect through Asia, from the east coast connect through the Middle East or India.
