Just a short ride east of Antalya along Antalya-Serik-Alanya highway and then up a 7km offshoot are the Kursunlu Waterfalls, which are yet another spectacle of nature in the region for those of you who don't mind a short walk prior to your cascade experience. Pay less than $2 USD at the entrance and stop for some basic Turkish delights at the cafe or souvenirs at the shop before or after your hike. The hike is short and generally easy, with plenty of shade and vantage points of the falls themselves as you get nearer. And although the falls are hardly a colossus of water volume, particularly in the dryer summer months, the setting is more natural and beautiful than the more frequented Düden falls due to the refreshing, teal pools and abundant pine forest.
If you've got a tight couple of days in Antalya, we would understand if you left a waterfall off of your must-see list. Then again, an afternoon here and in the incredible Greek ruins of Perge a few minutes drive southeast could end up being a highlight of your trip.
Note:Because this is a Turkish tourist attraction, you will also have the moderately expensive option of taking a camel ride to the falls. What the heck, you only live once.
