Panama is a good country, most people are friendly and helpful, however is always good to be cautious. When taking a taxi always ask how much would the cost of the ride be before getting on board. Most drivers are honest and will charge you the right ammount. If you feel that the cost of the trip is too high, wait for another taxi, there will always be an honest person who will charge you the right ammount for the service requested. If in doubt ask the person at the reception desk, surely the price of the service will be a little higher, but it will be safe and reliable. Another tip that I give to my tourists is to leave the original passport at the safe of the hotel, just carry a copy with you for any eventuality. Panama is a good country, with much to do and easy to remember too. Enjoy your stay.
