The rugged mountains of northern Luzon offer biking adventures amid fabulous scenery. Sagada is a popular base for a ride through mountain wilderness to Bontoc and then Banaue. The Nahtoban Caves offer incredible underground chambers perfect for caving, while the Heritage listed Banaue Rice Terraces are a man-made alternative for the keen trekker, reaching right up the mountainside and breathtaking from every angle.
