Fly fishing in Sian Ka’an is one of the most exciting activities in the Mayan Peninsula. There are great places to fish all through the cost, from the northern places near Cancún, in Sian Ka’an (near Tulum) and south to Xcalak and Ascencion areas almost on the Belice border.
I love Sian Ka’an because the scenery is just mind blowing. The canals connecting the different arms of the lagoon are beautiful. You can also go in and out to the sea using the Boca Paila canal (as shown in the video). You can also disembark at the mouth of the canal, when it opens up to the sea, and try some casts just where the canal waters meet the sea waves (great place for snook, especially in the winter season).
Sian Ka’an is one of the few places that you can get a grand slam (bonefish, tarpon, permit) in the same day. Also, super grand slams are common (adding a snook).
There are a few guide service providers. Boca Paila Fishing Lodge has been around for over 20 years, when nobody had heard of Tulum or Sian Ka’an (except some passionate fishermen). They have many plans, from a full day for 2 people at $400, to a complete week (including lodging and food) for $3600 per person.
You can also chose to stay at Tulum, just 30 minutes away from the lagoon, pick a great penthouse condo and pay less then $100/night in low season.
