The Cancun Underwater Museum is worth visiting. Although it was built artificially (in fact, there are some terracotta warriors and horses on the bottom of the sea), there is still a touch of touching when we really see it. We snorkeled when we were on a one-day trip to the sea on Women's Island, because we didn't start deep diving and were afraid that we would not be able to see it in case the light was not good enough and the sleep was not clear enough. We didn't expect to see it clearly, although there was a certain distance (because the Museum was at the bottom of the sea). All in all, it was a very interesting tour.
