In biological terms, the canopy refers to the upper layers of a forest, receiving much ot the sunlight and shielding what is below. There are many places in Costa Rica that have series of trails and suspension bridges that allow you to walk through the upper layers of the forest and gaze at what lies beneath.
We went to one yesterday afternoon. There were lots of steep hills without rails that were, um challenging to us old folks. Still, looking out and down from the bridges revealed wonders. I think this is some kind of fern but I'd be happy to be corrected.
The bad news today is that we have a family medical situation that requires us to come home today. The good news is the my Spanish seems to get less awful with every visit.
