San Augustin in Huatulco

I've been researching the ports on our 2015 Panama Canal cruise and am very interested in visiting San Augustin Beach when we stop in Huatulco, Mexico. Only problem is that I don't even know if that's feasible. Can it be reached by taxi? How long a drive from the port is San Augustin? Can we get a cab back to the ship easily?

I cannot find San Augustin mentioned in the Panama Canal ports section of cruisecritics. Surely someone has been there!

Any words of wisdom?

Huatulco is covered on the Mexican Rivera board, here:

Thanks, Cruiser Bruce. There isn't a lot of information, but you're right; there is some.

Thanks again.
