Rafting, Cordillera Central
Concierge.com's insider take:
Thrill-seeking types tend to gravitate toward the DR's longest river, Río del Norte, in the Cordillera Central region. The Class II to Class IV rapids include a precipitous drop called the "Mike Tyson" (which definitely packs a punch). Rancho Baiguate offers one-day tours from Santo Domingo, Puerto Plata, and Cabarete. No prior rafting experience is necessary, but you must be a good swimmer and over 12 years old. Tour prices are around $90 per person, and all gear is included. You'll just need to bring your own cojones (809-574-4940; www.ranchobaiguate.com).
