For anyone never having seen a mangrove, this is a must trip while visiting Los Tuxtlas.

You'll get to see white, red and black mangroves, lots of birds if the time of day is right, and spend 1 1/2
hours cruising mostly the open laguna and 3 or 4 one way mangrove channels.

Cost is 350 pesos per boat. Do not wait around to share a boat. You could spend the day waiting.

Access is via the busy Sontecomapan docks, half an hour by pirata taxi from Catemaco.
