Robin was probably a cocci in his past life. Kidding aside, he is so knowledgeable about the vegetation, animals, history of el yunque (and beyond) that aside from giving an excellent tour/hike of the rainforest you will end the tour still contemplating on nature/environment. he took us to high above beautiful waterfalls where we swam and got hydraulic massages, he taught rock climbing techniques, and took our photographs. i guess he can cater this activity fo those healthy and fit or for those who also just want to take it easy (we're the former!). this 8-12 miles activity was #1 on my 20yo daughter's list (above the bioluminescent tour!). Robin rocks, Robin rules.
The snails were the most common and only animal seen on the mountain, but the coquí (endemic frog on Puerto Rico) can be heard all over.
Of course being a tropical island these plants can be seen throughout the tropics. Please don't collect plants or pick their flowers - that's biologic GENOCIDE!!!!
