One of the best places to relax, exercise, enjoy the fresh air, ride a bike, or watch ocean-going vessels enter or exit the Panama Canal, is at Amador’s Marine Observation Point. There is no spot on the world quite like it.
I was there two Sundays ago, and took a couple of pictures of this convenient observation point at the entrance of the Panama Canal on the Pacific Side. This is what I saw. Take a look:

If you live in Panama City or are just passing by, I recommend you to drop over to this fascinating place and give yourself a break. You won’t regret it. Good Day.

Looks like a very nice relaxing place to unwind a little.
Hi gryphonscry:
Indeed it is. If you happen to travel to this part of the world, this is one of the places to visit in Panama.
