Possibilities:
Daytrip: We are located on Phi Phi Island (48 km from Phuket and 42 km from Krabi) and thats still "gamewater". The destinations around Phi Phi are the islands Koh Kiau, Koh Ha, Bamboo Island and Anemon Reef offer a good chance of sailfish, wahoo, tuna (skipjack, longtail, eastern little and bonito), mahi mahi, king mackerel, giant trevally, cobia, queenfish, rainbowrunner and baracuda.

Safaris: The safari can be custom made to suit the group ranging from phi phi to butang Island group up to the similans 55 miles west of Phuket. The best chance to catch a marlin, wahoo, yellowfin and dogtoothtuna is in the area of Similan Islands. The biggest marlin (black) caught in this area the weight was 210 kg. All the other gamefish what you can catch on a daytrip you can catch as well.
