Sri Lanka becаme in the last years more and more popular. For me, it’s a great alternative to Thailand. It’s cheaper, not that much touristic, and the locals don’t try to sell to you all the time.
We flew in Colombo, the capital, but decided to spend our first nights in the more chilled city Negombo. There is not too much to do but a good start to get an impression how Sri Lanka is like.
