Sri Lanka is a very beautiful country for tourism. It has natural beauty and it has some very important historical places. If you are a fan of Buddhism then you should make a visit to this country at least once in a life time. There is no doubt that Sri Lanka has a huge potential in the tourism sector. In fact, tourism brings significant portion of money for the neighboring country Maldives. So, there is no reason that Sri Lanka should not be able to do that.
I found an interesting report about it: Sri Lanka Tourism Looks to Boom After War's End
I am optimistic that tourism can soon become a billion dollar industry for the country. The good part is that it not only brings foreign exchange but also generates a lot of jobs in different corners of the country.
