You will have a couple opportunities to escape the hangovers, and sunburns if you head indoors to the Museo Historico de Acalpulco which is located within Fuerte de San Diego. This was built in the early 1600′s to keep away the dangerous pirates. Here you will be able to view a dozen or so exhibits that tell all about the old city and how maritime within the city has become so important. You can also see some other influences from the Chinese, Spanish, and Philipinos. There are some really cool Chinese artifacts to view. The best reason to check out this museum is not for the history it contains but rather for the delicious view you can have of the bay. Her you can see this awesome view for free.

Hotel Las Hamacas to Parque Papagayo
This is a long area of sandy beach that stretches along the coast heading away from the Old Acalpulco area. This area has only a couple tall buildings and the crowds are smaller here also. You can go by what some call the afternoon beaches and they have the names of Hornos, Playas Tamarindo, and Hornitos, These beaches are all along the walk from Las Hamacas Hotel and the Radisson Hotel. The reason people call them the afternoon beaches is because this is the time when the fisherman come back to town with their catches of the day. The smell in Tamarindo is nothing but fish guts. If you like to swim you should do so while you are here because the water is quite calm, and the beach sand is very soft to walk on. From the beach you can see all the way to the Pacific. If you are burnt out on baking in the sun you should head over to the Papago Park which is located between Costera and Cuauhtemoc. You can ride bikes, roller blade, and even take Segway tours in this area all around an island of monkeys. There is a pool for kids, birds from all over the world, and many places to play tag or hide and seek. You can take a dip in the adult pool if you get to warm. The park is open every day from 7am-8pm and the charge is 16 pesos to use the skating rink and 30 pesos if you need to rent roller skates. The pool is open 7am-8pm and will cost 16 pesos.
