This is a budget oriented trip I have undertaken last April. This comes under "World Tour Project". Everything I mention here are cheap and is great way to travel among Sinhalese culture and lifestyle.
About Srilanka -
The only country which is a neighboring to India and doesn't get affected by it, is SriLanka. It is the brother of India. Buddhism is predominent there. Hinduism too along with Christianity come second in place. People speak 2 languages - Sinhala, Tamil. I managed my entire trip with a little knowledge of Tamil. I met some of the amazing people in SriLanka. They are friendly and always are happy whenever you talk to them.
Recently tourism has increased so much. The places I travelled in Srilanka are - Colombo and Nearbys, Galle, Unawatuna, Kandy, Ella. Due to time constraint, I didnt travel the northern part of SL (well, I saw it through the flight!!!). Also it is hot in the north than the south.
This is my second foriegn trip and the first one which needed a visa. Visa can be applied online for 1200 Rs. You just have to show the letter to the Immigration people.
The cheapest flight is from chennai. Mihir Lanka is the flight carrier and service was good enough for the price.
