Deep limestone canyon with hiking trail through dramatic gorge scenery; accessible by dolmuş and bus from Ardahan for a full-day hike.
Posof Canyon cuts through limestone bedrock in the Posof district of Ardahan province, northeastern Turkey, approximately 80 km north of Ardahan city and close to the Georgian border. The canyon is formed by the Posof River, a tributary of the Kura, which has carved a narrow and dramatic gorge through folded sedimentary rock. The canyon walls in places reach 100 metres and the floor path follows the river closely, with several crossing points and sections where the trail narrows between vertical rock faces.
Access involves taking the Ardahan–Posof bus (approximately 1.5 hours, around 80 TRY from Ardahan otogar), which deposits passengers in Posof town. From the town, the canyon entrance is approximately 3 km on foot or by local taxi. The trail into the canyon is informal and follows the riverbank, requiring multiple simple river crossings. In spring (April–May), these crossings can involve wading through fast-moving water from snowmelt, making summer and early autumn the safest hiking period. By June the river has receded enough for most crossings to be made on stepping stones.
The canyon trail runs for approximately 4–6 km into the gorge before terrain becomes increasingly technical. The most rewarding section for casual hikers is the first 2–3 km, where limestone walls, river pools, and overhanging rock create a consistently dramatic environment. Wildflowers grow from cracks in the canyon walls from May through July, and the canyon floor receives direct sunlight only around midday, making it a cool refuge in summer heat.
Wildlife in the canyon includes kingfishers, various wading birds, and freshwater fish. The canyon is rarely visited by international tourists and is minimally signposted, giving it a genuinely undiscovered character. Local guides in Posof town can be arranged informally through the municipality for longer canyon walks.
Visitors doing Posof Canyon as a day trip from Ardahan should factor the return bus schedule carefully — afternoon buses back typically depart by 15:00–16:00, limiting canyon time to 2–3 hours. Staying overnight in Posof allows a more relaxed full-day canyon experience.

- Carry lunch and sufficient water — there are no facilities inside the canyon
When to visit
June to September for the safest river crossings and most reliable trail conditions. June has the best wildflowers on the canyon walls. Avoid April and May when spring snowmelt can make river crossings dangerous.

Frequently asked questions
How long does the canyon hike take?
The first 2–3 km of trail, covering the most scenic section, takes 2–3 hours return from the canyon entrance. A full traverse of 4–6 km takes 4–6 hours and requires experience in unmarked terrain.
Is the canyon suitable for children?
The canyon is suitable for children over age 8 with good outdoor experience, but river crossings and uneven terrain are not appropriate for young children or strollers. Adult supervision and waterproof footwear are essential.
Is photography allowed in the canyon?
There are no restrictions on photography in the canyon. The narrow limestone walls and river pools are particularly photogenic around midday when direct sunlight reaches the canyon floor.
