Dashed box: the approximate area used to count records (not the park boundary). Points are GBIF and iNaturalist records.
Yedigöller (Seven Lakes) National Park is in Bolu province in Turkey’s Black Sea region. It lies in a rugged part of the western Black Sea and is known for lakes formed when landslides blocked valleys, set in dense forest that Turkish sources call an “ocean of forest”. The highest point in the park is Eğrikiriş Hill (1,488 m) and the lowest Kirazçatı (465 m).
Camping, day picnics and walking are allowed in the park, which has guest houses and bungalows.
Why this route?
Bolu is the Black Sea province with the most macrofungi records. The box covers the forests around the city of Bolu as well as the national park, because the park itself has only a handful of records so far.
Getting there
Yedigöller National Park is in Bolu province. In winter, check road conditions before you set off.
Yedigöller is a national park: under article 14/d of Law No. 2873, "any production of forest products that would disturb the natural balance" is prohibited. Ask the park directorate before picking anything inside the park.
Data sources and licences
Observations from GBIF.org (human observations and herbarium specimens; records flagged with geospatial issues excluded) and iNaturalist research-grade records, retrieved 26 October 2026. Macrofungi only (Agaricomycetes, Pezizomycetes), named to species. Every point links to its own record, with the recorder and licence (CC0, CC BY, CC BY-NC).
An observation shows that a mushroom was seen there on that day, not that it is there now or that it may be picked. Counts reflect how many people record fungi in an area more than how common a species is.
