To the west of the Old Town of Veliki Kalnik is the Kalnik mountain lodge at 480 m above sea level, with the possibility of accommodation and meals. An asphalted road leads to it from Kalnik. Many hiking trails and paths lead to various hiking destinations from the mountain lodge. In 1996, the Educational Trail on Kalnik was built and opened in June.
On the rocks of the old Old Town of Veliki Kalnik and on the rocks north of the mountain lodge (7 zubi), there are hundreds of climbing routes, and paragliders take off from the plateau near the TV tower and the plateau west of the peak of Vranilec. To the east of the town of Veliko Kalnik, a rocky, mostly forested ridge called Kalnička greda stretches for about 4.5 kilometers, with the peaks of Vuklec (572 m), Podrevec (547 m) and Škrinja. Vuklec is a rocky peak covered with dense vegetation in the western part. There is a rocky peak called Podrevec around half of Kalnička greda, there is a marked access to it from the path to Škrinja. The lowest peak of Škrinja (about 500 m) in the easternmost part of the Kalnička greda is an 80-meter-long, bare, rocky ridge with beautiful views. There is access to it from the village mill in the village of Kalnik and from the mountain lodge on Kalnik.
To the east of Kalnička Greda is the long passage Vratno, which consists of the remains of the former village, the hunting house Vratno (a former log cabin) and Rinkov (an old lime factory). An old Roman road runs through Vratno, which cuts the ridge of the mountain deep to the north, from the initial 200 meters, all the way to above 350 meters.
