My dad and I did a 3 week tour with Susantha and he took us all over Sri Lanka! Overa Tours is a great tour company and Susantha was an excellent guide. He was a careful driver, was always on time, always helped with our luggage, helped with translation, and was always more than willing to help out and suggest activities to do wherever we went. If we needed something from a store, he would take us to the right place.
Susantha was patient and would get up at 4am if needed to drive me somewhere for a sunrise hike, like at Sigiria Rock (this was one of the highlights of the trip!).
We started in Negombo and went to the beach in Trincomalee for scuba/snorkel, went to Kandy to see the Temple of the Tooth, to Nuwara Eliya, Kithulgala for rafting and relaxation along the river, rode a train to Ella (a MUST if you visit!), and wrapped up our stay in the jungle in Sinharaja. We did three safaris for bird watching and elephant viewing, and a guided walk in the jungle in Singaraja looking for reptiles, insects, and birds.
This has been a trip of a lifetime, and it was fantastic having a driver. It makes traveling so much easier; no coordinating bus or train schedules, no calling taxis.
