Fun and beautiful! We took the snorkeling tour, the tour lasted about 4 hours. There is only one departure per day (9:30am), one important thing, on top of your tickets, there is a USD$10 dock fee per person, which is a government tax they have to collect before letting get on the boat.
The boat ride to the site is about 45 minutes, the staffs super friendly and nice! One thing I must say, the sea is kind of rough so prepare yourself if you easily getting seasick, there were about 25ish people in our group today, some people got quite seasick that they couldn't even get into the sea to snorkel by the time we got to the MUSA sites, so get yourself a pair of motion sickness wrist bands or take some motion sickness pills before you go!
The trip stopped at two different sites, first was to see the underwater sculptures (more rough sea), second near Isla Mujeres (calmer sea) to see corals and fish. I think the the price is quite reasonable. I must say since we were snorkeling with life jacket on, we could only see the sculptures from up top, not very clearly, if you want to see the details of the sculptures, do the scuba diving your instead.
Sun Screens are not allowed at this trip because they are harmful to the reefs, so if you are sensitive to the sun or easily gotten sunburns, you may want to wear long sleeves water gears! read more
