Can't choose? Don't. Spend half your trip landing colourful reef fish, the other half face-down in crystal-clear Atlantic. Perfect for mixed groups and first-timers.

Lock into a bull shark or hook a rolling silver king tarpon. These are bucket-list catches. Available April through mid-July during peak tarpon migration season.
As the sun disappears, the reef comes alive. Capt. Kevin's boat is rigged perfectly for after-dark fishing. Yellowtail snapper run hard at night under a dome of Keys stars.
