11 Trekking Routes Near Istanbul, Picked by Locals

Trekking is the easiest way to trade Istanbul’s noise for a few hours of quiet, and it doubles as a cheap way to meet people who like the outdoors as much as you do. Most trekking routes near Istanbul need nothing more than decent shoes and a free Saturday.

The 11 below run from a forest inside the city limits to a lake that takes half a day to reach. There’s no single best pick; it mostly comes down to how far you’re willing to drive.

1. Yalova

Yalova’s plateaus sit above the Marmara Sea, with Lake İznik visible on a clear day. Getting there means a ferry from Istanbul, and once you’re up, the route runs for roughly 18 km (about 11 miles) without any steep climbs. It tests stamina, not technique.

2. Polonezköy, Easiest of the Trekking Routes Near Istanbul

Polonezköy is about as gentle as trekking near Istanbul gets. The route is nearly flat. No real fitness required. It’s also one of the closest routes to the city, which makes it the easiest one to start with.

3. Gebze, Denizli Village

Say “Gebze” and most people picture factories, not forest.

Denizli Village is the counterargument. If you haven’t seen this side of the district yet, it’s worth putting on your first few routes.

4. Belgrad Forest

Belgrad Forest is the trekking route that never leaves the city—a roughly 5,500-hectare forest, dominated by sessile oak and straddling Sarıyer and Eyüp, with old Ottoman aqueducts and reservoirs along the way. You pick the loop length, so it works for a first outing or a longer one. Weekends get crowded. That’s the price of being this easy to reach, and it’s still the fastest way to get some oxygen and a proper walk without leaving town.

5. Abant Lake National Park, Bolu

Abant is farther out than the others on this list. Early risers can still do it in a day. Depending on the season, the trail around the lake can turn into a snow walk, which is part of why it’s one of the more popular routes here. Whether that counts as a perk or a warning depends on your boots.

6. Şile, Saklıgöl

Another low-key option for beginners is Saklıgöl, part of the Şile district. No long drive needed. It’s close enough for a day hike, and the scenery around the lake is genuinely one of the better payoffs for the distance.

7. Seben Lake, Bolu

Seben, also in Bolu province, is a reservoir lake well suited to trekking.

The caves and rock houses scattered around the area give the route a bit more character than a standard lake walk. The terrain isn’t demanding, either. A solid pick, then, if you want something a little different without extra difficulty.

8. Ballıkayalar Nature Park, Gebze

Want to stay close to Istanbul but switch things up? Point your route back toward Gebze. Ballıkayalar Nature Park and its canyon are a strong choice, and climbers come here too. Crossing the canyon suits hikers who like a bit of adrenaline—the name literally means “honey rocks,” and that rocky terrain means a few genuinely challenging stretches. Watch your footing; this isn’t a canyon to rush. First-timers are better off in Polonezköy or at Saklıgöl, while Ballıkayalar suits people who want their legs and nerves tested a little.

9. Uçmakdere, Ganos Mountains, Şarköy

Uçmakdere, in the Ganos Mountains near Tekirdağ, doubles as a paragliding spot, so it’s a good fit for anyone curious about combining sports. The slope can leave you a little breathless early on. Worth it, though. The view from up there tends to make you forget the climb.

10. Çubuk Lake, Göynük, Bolu

Çubuk Lake, ringed by pine trees and old windmills, has a gentle up-and-down route that makes for a pleasant walk. It’s less popular than Abant. For now, at least—it’s been gaining a following among regular trekkers in recent years, and the roughly three-hour drive from Istanbul ends in storybook scenery that makes the trip worth it.

11. İğneada Floodplain Forests

İğneada, near the Bulgarian border in Kırklareli province, protects one of Europe’s rare floodplain (longoz) forests, where the trees stand in seasonal standing water around lakes like Saka and Mert. The area has been a national park since 2007, run by Türkiye’s General Directorate of Nature Conservation and National Parks, so check that site for current access rules before you go. It’s flatter and wetter than the others on this list. Birdlife and scenery are the draw here, not elevation gain.
