The bog is estimated to be approximately 6,000 to 7,000 years old, formed through the gradual paludification of a former lake.
The peat layer in certain parts of the Pääsküla bog reaches depths of up to 6 meters.
The bog serves as a significant carbon sink, playing a critical role in local climate regulation.
It is one of the closest large-scale wilderness areas to Tallinn's city center, accessible within a short journey from the urban core.
The Pääsküla River, which flows along the edge of the bog, historically functioned as a border between surrounding parishes.
The Pääsküla bog trail is a 4-kilometer wooden boardwalk circuit located within a protected nature preserve on the southern outskirts of Tallinn. The trail provides access to a diverse wetland ecosystem, featuring a mix of pine forests, bog pools, and transition mires. A central feature is a wooden observation tower that offers an elevated view of the surrounding landscape. The area is home to various bird species, including cranes and birds of prey, and is frequently used for local hiking and nature photography. The boardwalk structure is designed to preserve the sensitive peatland vegetation while allowing year-round passage over soft, waterlogged soil. Interpretation signs along the route detail the formation of the bog and the specific flora found in the region.
