we didn`t see the town. we have booked, ourselves in the internet, a tour with a ship to snorkel and see an fisher town. the same tour is offered by Royal Carribean an cost more. was o.k. the fisher town was not good to see , the trip to an waterfall easy but not a must. Nice beach there.
All by yourself. The Old Fort is nearby the ship dock, over the street, the old town also. It is no problem to catch an bus and drive along the big bay (cost 5 peso p.P.).
Nice town Zihuatanejo where the sip arrived. Local buses or taxi to ixtapa. People say Isla Ixtapa is wonderful. to go to an beach in Z. by local boat is cheap.
