Catemaco and Los Tuxtlas promoters religiously push the same banal recommendations to visit the area.
Extreme sports are virtually overlooked and under appreciated. Many of the items mentioned below have been covered in this blog.
There is cave exploration along the shores of the Gulf of Mexico and around the San Martin Volcano.
Hang Gliding is possible off the 2000 foot drop at La Ventana in the Sierra Santa Marta, although I have never seen one flying.
Wreck Diving is possible off the northern shore of Los Tuxtlas.
Mountain Biking is possible most anywhere.
Kite, wind or sky surfing is possible much of the year, although, again, I have never seen someone doing it.
White water kayaking is seasonally possible on many of the Los Tuxtlas rivers.
Rock climbers could be in heaven, especially when ascending the steep faces of waterfall canyons.
Cliff diving and rappelling is possible off the Roca Partida rock face along the gulf.
Where else in the world exist opportunities like that in a 50 mile circumference?
The photo is of a recent 50K bike ride along the Catemaco Lake circumference. Because of political ineptness, there is a 5 km gap in the road which has to be transversed in many parts by carrying the bike.
