Akumal in detail
Increasing population is taking its toll on the reefs, but diving remains the primary attraction. For snorkeling, Laguna Yal-Kú is good value but can get crowded.
Beach access in the center costs M$100, which includes access to toilets, showers and a very swimmable beach. The hotel zone has limited free beach access.
Close to shore you'll have no problems with currents, though the surf can get rough.
