Just a four-hour drive from Colombo or a quick 30-minute domestic flight if your keen on saving time no matter the cost, missing Sigiriya should not be an option. Home to the iconic Lion Rock Fortress, a designated UNESCO World Heritage site, Sigiriya forms a part of Sri Lanka's Cultural Triangle. Climbing the rock during the early morning or late afternoon to take in the panoramic views, the sky palace, and moats, the site is home too, is highly recommended as it can get scorching hot during the afternoon and really zap your energy.
