If you are looking into a fishing excursion in Puerto Morelos, are you familiar with the Pelicano`s restaurant? ( The biggest restaurant direct on the beach right next to the park ) They have just opened a little kiosk beside the restaurant and sell fishing and snorkling excursions. The owners of the restaurant are my friends, as well as the guys that do the fishing and snorkling excursion. To rent the boat its 300usd. They supply the gas, bait, bottles of water and canned beer. The excursion is usually 4 hours and done in the morning. ( Lifejackets on the boat ) The boat holds 3 guest ( with 2 guides ) Also whatever you catch, they cook it for you at the restaurant Pelicano`s with side orders. Free of charge. Ask for Abraham. He has lots of experience and its his boat. I just got back last week from Puerto Morelos, i have been going for the past 4 years, about 3 - 5 times per year. I know these people very well and they are not scammers!
