Municipal Forest (Las Miejski)

A large working forest inside Olsztyn's city limits, often cited as the biggest urban forest complex in Europe, laced with marked trails and crossed by two rivers.

Reviewed and updated July 2026

The Municipal Forest (Las Miejski) is a large forest that sits within Olsztyn's administrative boundaries, and it is often cited as the biggest forest complex located inside a city in Europe. People come to walk, cycle and escape the streets without leaving town, following marked trails through pine woodland that shelters wild boar, roe deer and foxes. The main complex covers roughly 1,100 hectares (over 1,400 hectares in total), which makes it feel like open countryside rather than a park.

Pine woodland and two rivers

Pine dominates the forest, making up about 80 percent of the tree cover, with oak, beech and birch mixed in for variety. Two rivers cross the complex, the Łyna and the Wadąg, adding water views and quieter corners along their banks. The mix of tall conifers and broadleaf trees gives the woodland a different character season to season, from spring green to deep autumn colour. It is a genuine forest with wildlife rather than a landscaped green space.

Four marked trails for walking and cycling

Four marked walking trails run through the forest, so you can pick a shorter loop or a longer route depending on your time and energy. The terrain is gentle and the paths are easy to follow, which suits families, runners and cyclists as well as casual strollers. Because the woodland is so extensive, it rarely feels crowded even close to the city. Check signage at the trailheads or official city channels for current route details before a longer outing.

A major recreation area for the city

For residents of Olsztyn, this forest is one of the main places to spend time outdoors, whether that means a morning run, a weekend cycle or a slow walk in the trees. Its scale and the presence of wildlife such as roe deer and foxes make it more of a wild refuge than a typical city park. That combination, a working forest with real animals inside the city limits, is what earns it the frequent claim of being Europe's largest urban forest complex.

Fitting it into an Olsztyn visit

The forest lies in the northern part of Olsztyn, close enough to reach easily from the centre and pair with the rest of the city in a single day. Many visitors combine a couple of hours on the trails with the castle, the lakes and the old town covered in our Olsztyn guide. Bring water and comfortable shoes, and allow extra time if you want to reach the rivers. It is an easy way to add nature to a trip without organising transport out of town.

Good to know

Wear proper walking or cycling shoes and carry water, as the marked trails run for long distances through open woodland with few facilities.
