Bazalt Kayalıkları Tabiat Anıtı (Boyabat, Sinop): Practical Guide to Turkey’s Honeycomb Basalt Columns

The Bazalt Kayalıkları Tabiat Anıtı in Boyabat (Sinop Province) is one of Turkey’s clearest examples of columnar basalt—lava that cooled and cracked into striking polygonal prisms. You’ll find the formation near Kurusaray village (Fındıklık mevkii), about 15–20 km from Boyabat on the inland side of the Black Sea region. Trails, viewing terraces, and a small waterfall at the valley’s end make this a short, rewarding field stop for geology-minded travelers and photographers.

Why it’s special

• Rare columnar basalt in three neighboring valleys, with rectangular, pentagonal, and hexagonal columns. Several sources note typical heights up to ~30–40 meters.
• Protected status: The area was recognized as a first-degree natural site in 1996 and later registered (declared) as a Natural Monument in 2011, underscoring both its scientific and touristic value.
• Active visitor improvements: Recent info references waymarked walking paths, steps, viewing platforms, and rain shelters, indicating on-site infrastructure beyond a raw roadside viewpoint. | Dünyanın Parkurları

Quick Facts

• Location: Fındıklık area, Kurusaray village, Boyabat district, Sinop Province, Türkiye
• Approx. distance: 15–20 km from Boyabat center
• Coordinates: 41.4740932, 34.6411365 (Boyabat/Sinop region)
• Access: Short walks on signposted trails; final section leads to a small waterfall between the columns.

> Note on area figures: official and media sources differ on the listed size (you’ll see both ~10.25 ha and larger figures reported). Because of that mismatch, this guide avoids quoting a specific area.

Geology in plain language

When basaltic lava cools, it contracts and fractures into vertical columns—a process called columnar jointing. At Boyabat, cooling produced neat, honeycomb-like polygons (often 5–6 sides), then erosion later exposed the prisms along three adjacent valleys. Turkish cultural and scientific briefings date the formation to roughly 3–5 million years ago, a timeframe consistent with cooling and tectonic exposure of Neogene volcanics in the region. Portali

Planning your visit

Getting there

• By car: Easiest approach is by private vehicle from Boyabat; signage indicates walk circuits on arrival. Trip reports put the site ~15 km from Boyabat toward Kurusaray (Fındıklık). Roadside parking leads to short loop paths and panels that map suggested routes.

On-site layout

• Expect waymarked trails, steps, viewing terraces, and shelters; the waterfall is at the end of the primary path in the valley floor. Surfaces can be uneven and slippery after rain. | Dünyanın Parkurları

Best time to go

• Local guidance highlights spring (especially May) for wildflowers and comfortable walking temperatures. In summer, aim for early morning or late afternoon for cooler air and softer light on the columns.

How long to allow

• 60–90 minutes covers the short trails, photo stops from the terraces, and a look at the waterfall. If you’re doing detailed photography or macro geology shots, plan longer.

Photography & field notes

• Compositions: The honeycomb tops and column faces both work well—bring a wide-angle for walls and a short telephoto to compress column geometry. Elevated terraces help keep people out of frame. (Examples of the columns’ scale and look appear across news and social posts.)
• Light: Side-light in early/late day emphasizes prism edges. After rain, the wet basalt deepens in tone, creating high contrast with vegetation.
• Safety: Stay behind rails and keep off unstable stacks; drying cracks can be slick with algae or clay fines at the valley floor.

Responsible travel & access considerations

• Trail impact: Stick to the built steps and marked lines to prevent erosion along the toe of columns. | Dünyanın Parkurları
• Facilities & hours: This is a natural monument, not a full theme park. Some booking sites advise confirming on-site hours/conditions locally (especially after storms). There may not be staffed ticketing every day.
• Mobility: Paths include stairs and uneven ground; wheelchair access appears limited based on current trail descriptions. If in doubt, check locally before you go. | Dünyanın Parkurları

Context: protection and development timeline

• 1996: Area designated a 1st-degree natural site (protection category in Türkiye).
• 2011: Registered as a Natural Monument by authorities (Tabiat Anıtı), emphasizing its rarity and research value.
• 2023–2025: Regional coverage highlights ongoing efforts to strengthen tourism access while protecting the formation—consistent with the new trails and viewing structures now reported by hikers. Ajansı

What to pair it with (nearby interest)

Boyabat is known for castle ruins and traditional houses, and the broader Sinop region offers Black Sea landscapes and small agricultural valleys. If you’re building a day route, combine the basalt stop with Boyabat town for lunch and supplies before heading back toward the coast at Sinop.

Essential tips (save this list)

• Footwear: Trail shoes with good grip; surfaces can be slick near the waterfall.
• Weather: After heavy rain, expect muddy approaches and pooled water on lower paths. | Dünyanın Parkurları
• Navigation: Search for “Bazalt Kayalıkları Tabiat Anıtı – Kurusaray/Fındıklık, Boyabat” in your map app. The Boyabat municipality and regional pages use that naming.
• Time of day: Early/late light = better texture on columns; mid-day is harsh.
• Leave no trace: Pack out litter; this is a protected geosite.

How the science looks up close

Look for cooling joints that meet at roughly 120°—the geometry behind those tidy polygons. At Boyabat, columns commonly show 4–6 sides and vertical jointing; erosion has undercut some faces, exposing prisms at eye level. The Black Sea region’s volcanism here is Neogene in age, with publications and briefings citing ~3–5 million years for the columns. That lines up with similar columnar basalt ages worldwide. Portali

Accuracy & data checks

• Ages and morphology are drawn from official culture/forestry pages and encyclopedia entries. Portali
• Heights (up to ~30–40 m) appear consistently in traveler and press descriptions; expect variability by valley.
• Access infrastructure (trails/terraces/shelters) is referenced in 2024–2025 hiker reports; conditions can change with weather and maintenance cycles. Verify locally if mobility or time is critical. | Dünyanın Parkurları
