Ilgaz Mountains constitute the eastern part of the second range from the coast line at an average distance of 100 km (62 mi).

[2][3] The state highway D.765, which connects Black Sea coast to Central Anatolia is 10 km (6.2 mi) west of the peak.

[5] The mountain mentioned by Ptolemy under the name of Ligas, Gigas, or Oligas,[6] is probably the same as the Olgassys of Strabo.

The distance from Ankara is 200 km (120 mi), which makes the park nearest winter sports resort to the capital city citizens.

The popular name of the forestry around Ilgaz Mountains is "sea of trees" (Turkish: ağaç denizi).

In 1996, a new insect species was discovered in Ilgaz Mountain ecology and in 2010 it was named as Merodon Ilgazense.
