Belgrad Forest Walking Trails, Picnic Areas and Ottoman Aqueducts

Belgrad forest walking trails in Istanbul

Belgrad Forest sits about 15 kilometers north of central Istanbul, above Sarıyer, and it is the closest thing the city has to a proper woodland walk. The main paved loop around Neşetsuyu is roughly 6.5 kilometers, mostly flat, and shaded by oak and beech the whole way. In August that shade is the reason to come.

The forest covers around 5,500 hectares, and most of it is left as watershed for the reservoirs that fed the old city. You do not walk all of it. You walk one of the marked recreation areas, and the two most useful are Neşetsuyu and Bentler. Both have parking, tap water, and the paved loop that makes this doable for anyone with normal shoes. Belgrad Forest is part of Istanbul's broader collection of hidden places and quieter walks that lie just beyond the main tourist circuit.

Don't come expecting mountain scenery. This is gentle, green, flat-to-rolling forest with a couple of reservoirs and some old stone waterworks. If you want a half-day out of the concrete without leaving the city limits, it does the job well.

How do you get to Belgrad Forest from central Istanbul?

Get to Sarıyer first, then take a bus up to the forest. From the European side, the fastest route is a ferry or the metro to a Bosphorus point, then bus 25E or 40 up the coast to Sarıyer, where you change to the local line that climbs to the forest gates. Budget about 90 minutes door to door. If you are exploring the north coast, the Sarıyer fishing village and Bosphorus waterfront makes a natural pairing with a forest visit.

The cleanest version: take the M2 metro to Hacıosman, the northern end of the line, then a taxi or a connecting bus up to the Neşetsuyu entrance. A taxi from Hacıosman runs roughly 200 to 300 lira in 2026 and takes 15 minutes. If you would rather do it all on public transport, İETT runs buses from Sarıyer toward the Bentler and Neşetsuyu gates.

For working out the exact bus numbers and departure times on the day, Moovit is more reliable here than Google, because it carries the İETT local lines that change with the season.

If you are two or three people, splitting a taxi from Hacıosman is often faster and barely more expensive than the multi-leg bus chain. Weekends bring heavy traffic on the approach roads, so aim to arrive before 10:00 if you are driving or riding up on a Saturday.

How long is the walking trail in Belgrad Forest?

The main paved loop at Neşetsuyu is about 6.5 kilometers and takes most people 90 minutes to two hours at a relaxed pace. It is flat enough for a stroller and popular with runners, who treat it as a fixed circuit. The Bentler area adds shorter connecting paths if you want to stretch it toward the reservoirs.

There is no single trail through the whole forest, and wandering off the marked loops is discouraged because much of the land is protected watershed. Stick to the paved and gravel recreation circuits. If you want more distance, link Neşetsuyu to the aqueduct spurs and you can build a 10-to-12 kilometer day without repeating much.

Bring water even though there are taps, and bring your own food. The kiosks near the entrances sell çay (Turkish black tea served in tulip glasses) and simple snacks, but they close early and the choice is thin. This is a pack-your-own kind of place.

What are the Ottoman aqueducts in Belgrad Forest?

The forest holds part of the network of dams and aqueducts that supplied water to Ottoman Istanbul, some of it dating to the 18th century and earlier. The most photographed structure is the Uzunkemer, a long multi-tiered stone aqueduct, and the Sultan Mahmud dam sits among the reservoirs the trails pass. These are the reason the forest was protected in the first place.

The reservoirs you walk past, called bentler in Turkish, are the old collection dams. Several are still intact and you can walk right up to the stone faces. The Istanbul Metropolitan Municipality parks pages list the recreation areas and their facilities if you want to confirm which gate has parking before you go.

You do not need to plan a history route around them. Walk the Neşetsuyu loop and you pass the waterworks naturally, with signboards at the bigger structures. It is a quiet way to see 300-year-old engineering without a ticket queue.

Come on a weekday if you can. Saturdays and Sundays fill the picnic areas with Istanbul families and their mangal grills, which is its own kind of good, but the trails are calmer Tuesday morning.
