Grand Slam Fly Fishing Lodge


The Sian Ka’an Biosphere is a protected World Heritage site where all commercial fishing is banned, other than lobster trapping. There are no nets anywhere and this policy is strictly enforced by both the Mexican Government as well as the 47 fishing guides who are licensed to work in the park. What this means for anglers is that the fishing is consistently excellent and getting better every year since the commercial ban was put into place.

The long narrow peninsula that runs from the mainland down into the heart of the biosphere has created a large back lagoon that runs for close to 45 kilometers back up to the mainland. This lagoon is incredibly productive and holds all manner of flats species. The guides will go as far north in the lagoon as the Boca Paila Bridge in search of tarpon, snook, bonefish and permit. This back lagoon area holds some of the best places to wade and stalk bonefish in the entire biosphere. Hard packed flats offer good solid footing and the white sand allows anglers excellent visibility to see fish from along way off. In these areas, bonefish will often be found tailing in close to the mangrove lined shore.

At the south end of the peninsula, the mighty Ascencion Bay opens up to the south and west, stretching back to the mainland. Ascencion Bay is actually a series of smaller bays and lagoons that combine to create one vast flats ecosystem that is nothing short of an anglers paradise. Miles and miles of skinny water flats run in every direction, interconnected by creeks and channels that act as highways for both fish and the skiffs that chase them. It would likely take 20 trips to really get a handle on this fishery and what it holds for flats fishermen.

Many scattered islands dot the southern part of the bay, with only the most prominent having names. Cayo Cedro and Lagartijas hold some nice sized bonefish and if you head further west, the Islas Tres Marias is a spectacular area for permit, tarpon and snook. One of our all time favorite places to fish in Ascencion Bay is the enormous Xobon Flat, which rises up from the depths in the middle of the south west part of the bay. This huge white sand flat holds both bonefish and permit and offers excellent wading opportunities for both species. There are also several lagoons further west of Xobon that will hold big tarpon starting in the spring.

Aside from the hundreds of miles of untouched flats to fish, this entire area is so special because of the species diversity found in Ascencion. Bonefish, tarpon permit and snook are all available during the year, regardless of when you come. The snook fishing in particular gets very little mention compared to the other Big 3 flats species, and that is not doing this species justice in terms of the quality fishing that this species offers in Ascencion. This is a strictly enforced catch and release environment. The snook, which are usually one of the first fish to be harvested from an area because they are such a good eating fish, are thriving all over Ascencion Bay. This is a Top 3 global destinantion for a Grand Slam.


The skiffs are 25 foot fiberglass Mexican Pangas powered by 60 HP four stroke engines. These skiffs draw very little water for their size and come equipped with radios, rod holders and generous casting platforms.


Guests will fly into the Cancun International Airport. Upon clearing customs, guests will exit the customs area and walk to the arrival lobby which is outside. It’s a bit chaotic at times but the Grand Slam Lodge representative will be there holding a sign, ready to meet you. He will escort you to the van for the trip down to the lodge. The drive from the Cancun Airport down into the Sian Ka’an Biosphere takes about an hour and forty five minutes. Because the dirt road down to Punta Allen is notorious for frequently being in terrible shape, the lodge has done something really clever that allows guests to avoid the up to 2 hour bumpy ride down.

Just inside the reserve, guests will be transferred from the van to a waiting boat and the boat will then take guests directly to the lodge. Instead of a kidney rattling couple of hours in a van on the dirt road, guests will instead be cruising through scenic mangrove lagoons with a cold beer in hand. The scenery is spectacular and cuts this leg of the trip from 2+ hours down to just 45 minutes. It’s a wonderful way to start the trip and the way down by boat is through a protected series of gorgeous lagoons offering beautiful scenery. In order to secure this option, guests will need to land in Cancun no later than 2 pm on their arrival day.

The second level bedroom has one king-sized bed, a living area, and a balcony with a hammock.

The rooms are very comfortable and about as good as we have seen anywhere. Rod racks outside on the balcony of each room are a nice touch and the views are of the beach and well kept grounds of the lodge. Inside, the rooms are spacious and well laid out. Excellent A/C units keep the rooms cool and the large flat screen TV’s offer satellite service so guests can keep up to date with the latest news or sporting event.
