The Caribbeans best... No matter where you have been in the Caribbean,  we know you will find the Western Caribbean to be relaxing, memorable, and affordable.   The Rio Dulce has been on the charts for decades,  so isn’t it time for you to find out why?   If you are a world traveler or circumnavigating the Caribbean you already know that Marios is the must stop location.  This is for good reason,  our guests recognize the added value in a marina that is family owned and operated.  Marios offers a relaxed yet fun ambiance located far enough away from town to enjoy the serenity offered by the river, but close enough to reap the benefits of the local town of Fronteras.  We know you want to experience the sights, sounds and unique aspects of the culture that make up each destination.  Our mission is to assist you in accomplishing your goals whether you are looking to relocate your boat here or want to explore Central America on your way to the Panama Canal.  We are your first and best choice
