    Marathon Reef & Wreck Fishing Charters - Our Most Popular Adventure

    Marathon reef and wreck fishing is popular with experienced anglers and first time fishermen, both young and old. Bottom fishing doesn't require any specialized skill-set - you simply wait for the bite and set the hook. The only real test comes when you have to reel in massive fish like barracuda, shark, cobia, or grouper - fish that will put a bend in your rod and leave your arms aching.

    Another benefit of these Marathon fishing adventures is that you are targeting some of the best eating fish in the ocean. The white, delicate flesh of snapper is renowned, and is on many people's list of favorite fish.

    On our reef and wreck fishing charters, we supply all of the weights, splitshots, hooks, leaders, and bait you need to find quick success. We have a long list of exclusive fishing spots where we target bottom fish that include:

      Yellowtail Snapper

      Mangrove Snapper

      Mutton Snapper


       Mackerel - King, Spanish, and Cero




      ..and Many More


    We offer Marathon reef and wreck fishing either as a private charter, or for an inexpensive $59.99 per person for a shared charter. This is the perfect fishing charter for families with small children or novice anglers who are simply looking to get their feet wet without gouging your wallet.
