• Kiwanis trail: starting from the town of Chibougamau, the Kiwanis trail circles Gilman lakes. This trail has a shortcut via the Hydro trail, partially skirting each of the lakes.
• Rustic Trail: this trail is taken via the Kiwanis Trail; the two trails join at the western end of Petit lac Gilman. Hikers can climb to the top of Mount Helios. This mount was named in honor of the Greek sun god. At the top, the view is magnificent over the city of Chibougamau, Chibougamau Lake and Dorés Lake.
• Lake Sauvage trail: this trail passes through the lake of the same name and ends at Chemin Campbell.

This site was first used by the Crees. This area is still a trapping territory for the Cree community of Oujé-Bougoumou. In 2005, a forest fire ravaged the park.

In the park, the visitors might see snowshoe hare, spruce grouse, ruffed grouse and red fox. Occasionally, it is possible to see the Canada lynx here and the rarer black bear.

The toponym "Obalski regional park" evokes the memory of Joseph Obalski (1852-1915), a mining engineer who had the merit of having confirmed the presence of significant copper deposits in the region.
