Hi, I plan to be in Negombo for a few days next week, and I would like to have an excursion to visit Sigiriya. Please could you advise me what is the best way to get there? Shall I take a taxi from Negombo or is there any reliable public transport? Would you know if there is any bus excursion company for a kind of one-day trip based in Colombo maybe? Thanks a lot!
