Las Marquesas, arre those keys 2O miles West of Key West, although they seem close enough to go, going is a whole other story, you have to get oragnized, bring water, food, camping gear, gas, and hope that the ocean will be nice to you, because very view skiffs make it there. And “there” is fly fishing paradise! Nobody ever goes, it’s too much of a hassle. So only big boats can go where tarpon are waiting to dance with you. World Angling, organizes those kind of trips!
