Except for the hyper touted boat tour to the monkey islands of Laguna Catemaco, and the placid drifting in
the mangroves of Laguna Sontecomapan, there is very little touring available in Catemaco and Los Tuxtlas

If you are Mexican, there are dozens of tour buses hitting Catemaco on the weekends and hundreds more
during holidays from many points in Mexico. Dive tours, ecotourism tours, prayer tours, Eyipantla and
hyped nature tours, etc.

At the English speaking end, there are high priced US birding expeditions, RV herds and not much else.

If you are a little bit adventurous, it is possible to create dozens of opportunities to create your own tour.
