Costa Rica: what to do

I did a little research into my mother's Holland America cruise through the Panama Canal and the Costa Rica port of call is on the Pacific side (so after the ship has gone through the canal from the Caribbean side).  That's where we went, the Pacific side.  We went to Quepos near Manuel Antonio National Park.  The ship stops at Puntarenas area which is further up.  I definitely suggest a nature walk in the canopy with hanging bridges.  Holland America has an excursion called Sky Way.  I'm hiking in the picture above but not on the Pacific Coast, rather more inland, but it's the same concept.  You will be amazed at how much wildlife your guide points out to you.
