Less than 1% of Puerto Rico's virgin forests remain—which makes a visit to the Caribbean National Forest, better known as El Yunque (the Taino Indian name for its highest peak), all the more impressive.
About an hour's drive southeast of San Juan, El Yunque is home to hundreds of plant and animal species, including 240 species of trees (you'll see orchids growing on some) and the endangered Puerto Rican parrot. The forest blankets 28,000 acres/11,340 hectares and boasts peaks rising more than 3,400 ft/1,035 m above sea level.
Most visitors start at El Portal Visitors Center (daily 9 am-5 pm). Exhibits at the handicapped-accessible facility range from high-tech multimedia displays to a giant light-up map that shows how the rain forest supplies water to huge sections of the island. At El Portal, visitors can see a movie about El Yunque, then obtain maps on picnicking areas, drive-up waterfalls and hiking paths.
To appreciate the beauty of the forest, take a hike. Trails range from the strenuous 12-mi/19-km trek uphill to El Toro Peak (3,532 ft/1,077 m above sea level) to the gentler path that begins at the Sierra Palm Visitor Information Area. Most tour companies offer trips to El Yunque, but you can also take a taxi—expect to pay about US$20 per hour, including waiting time, or as much as US$100 for the trip. Be aware that the trails can get very crowded—don't expect solitude except in the off-season. The park, which is open daily 7:30 am-6 pm, is the only tropical rain forest administered by the U.S. Forest Service. Phone 787-888-1810.
Nearby is Luquillo Beach, which is shaded by coconut palms and has changing rooms. Horseback-riding trips can be arranged through Catch A Dream (phone 787-409-0155 or 787-409-9360) at Hacienda Carabali.
Also nearby in Rio Grande are the Westin Rio Mar, a huge resort with two championship golf courses, and Sol Melia's Paradisus Puerto Rico.
