Panama City, Playa Coronado
The beaches in Panama City are dirty. If you want to relax under the sun and go for a swim, you can go southwest to San Carlos and Anton. A public bus will take you there in a couple of hours. Buses run from first thing in the morning to late at the night. In this area there are hotels, bungalows, and a very popular all inclusive resort. You can also go to the beach on a one day excursion, though.
Other nice beaches are on the unique island of Contadora, On Archipelago Las Perlas. You can get to the island by plane, 15 minutes, or by boat, two hours. In the island there are hotels and tourist facilities.
Panama has a tropical climate. Beaches in the area can be visited all year round.
