Old San Juan (Viejo San Juan) is the historic core of San Juan. Although this eight by ten block district is part of San Juan, it is quite geographically and culturally distinct from the rest of the city. It occupies the western half of the islet of San Juan, which it shares with Puerta de Tierra. As this is a tourist destination, English is relatively common, but not universally spoken.
The El Yunque Rain Forest is a cool, mountainous, sub tropical rainforest. The Eastern side of the Luquillo Mountains, which has the El Yunque rainforest at the top elevations, gets most of the rain.. .
“The sub tropical ‘Rain forest’ occupies very little area in Puerto Rico, only a single, crescent shaped, band on the windward side of the El Yunque mountains. It lies wholly within the El Yunque National Forest Reserve. Its’ main features are the Sierra Palms and a superabundance of epiphytes.”The actual rainforest is at the top, you must drive to the top of the road and hike up to see the cloud or dwarf forest.
