Indian tourist visa in Colombo, Sri Lanka (cheaper)?

Indian tourist visa in Colombo, Sri Lanka (cheaper)?

I know India needs visas for both Norwegian and Canadian nationals, and I've heard they hand out wonderfully long six-month visas. Of course, purchasing a visa in either Canada or Norway would prove expensive, maybe more than 50 euro. My question is, since I am going to Sri lanka first (and spending 10 or so days), should I apply for an Indian visa in Colombo the first day, have a look around, wait for the visa to clear, and stamped in the passport, then catch a cheap flight to Kerala, South India, just over the water? How much would an Indian visa (tourist status) cost in Colombo? Are there are special requirements needed, for example I heard applying for an Indian visa in Sub-saharan Africa requires an additional Yellow Fever vaccanination certificate, regardless of your nationality. Does India require similar paperwork from Westerners arriving via Sri Lanka as well? Thanks

Hello,
It takes five working days from Sri Lanka. What with holidays, weekends etc, better to allow 7 or 8.
In Colombo the immigration dept is located at; 40, Ananda Rajakaruna mw,
Colombo 10
web site gives all the deatails at www.immigration.gov.lk
Theres also an indian visa section at the Indian high com in Kandy. Its situated on the hill opposite side of the lake to the temple. Kandy is much nicer, less busy and not a bad place as a base to inspect the island.

The Yellow Fever certificate in Africa is because there is Yellow Fever in Africa..
