About an hour's drive northeast on the road to Side is one of Antalya's most impressive natural gems, Köprülü Canyon. A 14 km (8.7 mile) stretch of the Köprü River with gorges nearly 400 meters (over 1300 feet) high at some points, you may want to hike the ancient Roman bridges and lofty cliffs on your own. Then again, to truly enjoy what this national park has to offer you just may have to succumb to the pushy on-site tour providers and experience it from the river itself.
If a white water rafting adventure is in the cards, then be prepared for a few km where class 2-3 rapids alternate with more relaxing sections. Most rafting operators will stop to let you swim in the midst of a number of waterfalls and even do some cliff jumping along the way, while locally caught trout is often included for lunch in an asking price that will come to around $30 per person. Not bad for a little exhilaration, natural beauty, and a full belly. Then again, you could save your money and hoof it across the old stone Oluk Bridge and the trails that circumnavigate the canyon that provide a half day or so of hiking without too much of a challenge. Either way, whether you're looking at Köprülü Canyon as a day trip in itself or as a way to spice up a visit to the former Greek colony of Selge, it's a quality adventure destination worth a few hours of your time.
