Bačko jezero is a small lake in the Primorsko-notranjska region of southwestern Slovenia. It is a quiet spot for a short stop in the karst countryside of inner Carniola, where surface water is relatively rare. The lake lies in the area south of Ilirska Bistrica, so it can be combined with other outings in that part of the region.

Udin Woods (Udin boršt) is a protected forested area in the Gorenjska region, on a conglomerate plateau between Kranj and Tržič, known for its small caves and rock shelters. It suits an easy woodland walk on forest paths, with the caves as quiet points of interest along the way.
Wild Lake (Divje jezero) is a small lake fed by a karst spring that rises from a deep underwater shaft at the foot of a steep forested cliff. After heavy rain the water can surge up and spill into the short Jezernica stream, one of the shortest rivers in Slovenia. It lies just outside Idrija in western Slovenia and is reached by an easy walk.
Snow Cave (Snežna jama) is a cave in the mountains of the Savinjska region in northern Slovenia. It is one of the higher-lying caves in the country, and as its name suggests, snow and ice can linger inside. Reaching it involves a mountain approach in the upper Savinja valley area, so plan for a hike rather than a roadside stop.
Planšarsko jezero is a small lake in Jezersko Municipality, in the Gorenjska region of northern Slovenia. It sits in the Alpine valley of Jezersko, close to the village, and makes an easy stop on a day out in the area. The surroundings suit a short, level walk around the shore.
Kostel Castle is a castle ruin in southeastern Slovenia, standing on a hill above the Kolpa valley close to the Croatian border. The remains of its walls and towers give a sense of how the stronghold once watched over this border area. It lies in the Kostel area of the Kočevje region, a quiet stop for those exploring the Kolpa river.
Potok Cave (Potočka zijalka) is a high mountain cave on the slopes of Olševa in the Karawanks, in the Savinjska region near Solčava. It is one of the best-known Palaeolithic sites in Slovenia, where excavations uncovered cave bear remains and bone tools left by Ice Age hunters. Reaching it is a mountain hike, so plan for a proper walk on marked trails rather than a short stroll.
Kojca is a mountain in the Goriška region of western Slovenia, listed here as a viewpoint. From its summit you look out over the surrounding hills and valleys of the area. Reaching it means a hike on mountain paths, so plan for a proper walk rather than a short stroll.
