Saklikent National Park

Saklıkent Gorge, meaning "hidden city" in Turkish, is one of the longest canyons in Turkey, cut roughly 18 kilometres into the limestone of the Taurus Mountains by a fast-flowing, ice-cold stream. Its walls climb as high as 300 metres in places, narrowing in sections to only a few metres across, and the gorge sits within Saklıkent National Park, established in 1996 in what was then Fethiye district — the area became part of Muğla's Seydikemer district after a 2014 administrative change. It lies about 50 kilometres inland from Fethiye and 65 from Kaş, close enough to the coast that most people see it as a half-day trip from either.

How the Gorge Was Cut

The canyon is the work of the Karaçay, the "black stream", a mountain watercourse that drains the flanks of the Akdağlar range and eventually feeds the Eşen River. The rock it cuts through is limestone — soluble and heavily fractured — and the region sits in one of Turkey's most seismically active zones. The combination of tectonic fracturing and thousands of years of running water is what produced a slot this deep and this narrow rather than a broad open valley. Around 16 small caves have been recorded in the canyon walls, and where the walkway ends, karstic springs burst straight out of the base of the cliff. That underground origin is why the stream stays painfully cold even in August, when the air outside is well above thirty degrees.

The national park was declared by cabinet decision on 6 June 1996, originally covering a little over 12,000 hectares straddling the Antalya and Muğla provincial boundary. The protected area was subsequently redrawn and now measures roughly 1,643 hectares, the great majority of it on the Antalya side. Red pine forest covers the slopes around the canyon mouth, and the park is used for trekking and picnicking as well as for the canyon walk itself.

Walking the Canyon

Most visitors walk the first stretch of the canyon along a wooden walkway fixed to the rock face, then continue on foot through the shallow, running water; the full route is generally only passable after April, once meltwater from the Taurus peaks has cleared. The walkway runs about 200 metres, bolted to the cliff on iron brackets above the water, and takes only a few minutes to cross; a replacement structure was built in 2024. At the far end you drop down to the streambed, wade across the confluence where the current is at its strongest, and from there the canyon floor is open for roughly 4 kilometres in an ordinary summer.

That first crossing is the part people remember: the water moves fast, the bed is loose gravel, and the cold is sharp enough to sting. Beyond it the walk is easy but permanently wet, the stream running anywhere from ankle to knee depth depending on the season, so grippy water shoes matter more than anything else you carry. Going further than the accessible section — the canyon continues for another dozen kilometres or so — is a technical canyoning route with fixed abseils and something like thirty waterfalls, undertaken only with operators and proper equipment. Local operators also run rafting trips on the river below the gorge, and further along, where two streams meet, a patch of mineral-rich mud is used informally for open-air mud baths.

Tlos and the Xanthos Valley

Nearby, the ruins of the ancient Lycian city of Tlos add a historical detour to the trip. Tlos is among the oldest settlements in Lycia, with occupation traced back to the second millennium BC, and it was one of the six leading members of the Lycian League, holding three votes in its federal assembly. Its acropolis stacks the region's whole history into a single hillside: Lycian rock-cut tombs carved into the cliff face, a Roman theatre and stadium on the slopes below, and at the summit an Ottoman-era fortress associated with a local strongman remembered as Bloody Ali. The best known of the tombs is attributed to Bellerophon, the hero who in Greek myth rode the winged horse Pegasus, and its façade carries a relief of rider and mount. Tlos was added to Turkey's UNESCO tentative list in 2009.

The same valley holds Xanthos and Letoon, the ancient Lycian capital and its sanctuary, inscribed together as a UNESCO World Heritage Site in 1988. Between them, the gorge and the ruins make a natural pairing for a day inland, and most organised excursions from the coast combine at least two of the three.

When to Go and What to Expect

April to October is the practical window. Before April the meltwater makes the canyon floor impassable and the gate down to the streambed is usually shut; after heavy rain in spring or late autumn, access can be closed at short notice. Midsummer is the most reliable and also the busiest, so an early start is worth the effort — the site opens in the morning and coach parties tend to arrive from mid-morning onwards. There is a modest entrance fee, and shops at the gate rent water shoes to anyone who turns up unprepared. Swimwear under dry clothes is the sensible approach, since you will be wet from the knees down within the first two minutes.

At the entrance, a cluster of restaurants sets low tables on platforms built directly over the running water, serving gözleme and trout — the standard end to the walk, and a reasonable way to dry off. Combined with the region's coastal scenery, the gorge has become a classic stop on a Fethiye blue cruise itinerary for guests who want to add a day of hiking to their time on the water.
