"Beji Guwang Hidden Canyon, a Sukawati-based ravine and sacred Balinese site, feels hidden in plain sight. Beyond the ticketed entrance is a series of mid-rise canyons lining the Oos River: prepare to climb, wade, swim, and scale your way through a rocky-tropical landscape not seen anywhere else on the island. A bonus? Touring hordes have yet to discover it. The mesmerizing, sculpted-by-erosion stone walls are even more magnificent with sunlight and shadow play. Leave it to the competent tour guides to take your snaps at all the right angles. Beji Guwang Hidden Canyon is a plum choice for travelers who need more than surfing to get their blood pumping. Prices start at around $15 for an individual (it's less expensive with two or more people) and includes entry, a local guide for up to four guests, a bottle of water, bath and face towels, and lockers and showers." - Travis Levius
