If you're real keen on fishing you'll be glad to know that big game fishing is all the rage in Hikka. There are many good operators in the area who offer deep sea fishing tours. But be sure to book a tour that's skippered by professional fishermen under safe standards and are inclusive of refreshments, as you don't want to be stuck on a boat for 3-4 hours without any food. If you like, some of these tours can also extend up to half day and whole day trips.
During your tour, you'll be fishing for big game such as sailfish, tuna, wahoo, dorado (dolphinfish), barracuda, king mackerel, marlin and the giant trevally.
