The silver lining of that major blunder which left me scuttling back to EWR airport at 02:34 after getting off the last NYC-bound train was my arrival at the Oculus before daybreak and having the mezzanine all to myself. That, before getting reprimanded by an officer that tripods are not allowed and being told by another to never leave my luggage out of sight.
“El Arbor Hueco / Ficus Tree” in Google Maps should easily lead you to it through a path into the woods near the Monteverde Cloud Forest Lodge signage. Found out later though that I was at the wrong tree, as there was a bigger and hollower one. Don’t leave your belongings “alone” when climbing, I was also told thereafter.
Once you hit the river after going down the path from the highway, follow it downstream to the right where the Ficus Tree Bridge awaits you. Forgot this instruction on my first attempt to look for it and went straight ahead ’til I saw a sign which read: “Do not pass. There’s a crazy man with a gun.”
