Marble Cave

The Marble Cave is a smaller, less-known alternative to Baredine. The walls have a marble-like appearance (that’s where the name comes from), and the formations inside are genuinely beautiful.

What to Expect

The tour is about 30 minutes — you’ll see stalactites, stalagmites, and rock formations in colours ranging from white to rusty red. The main chamber is surprisingly large.

The Wine Twist

The cave stays at a constant 14°C, so a local winery ages their wine in barrels down here. You can see them during the tour and taste the wine afterward.

My Tips

Combine with lunch nearby. The cave is on a family agrotourism property — you can have a meal with local produce after your visit.

Good for hot days. When it’s 35°C outside, ducking into a 14°C cave is refreshing.

Less crowded than Baredine. If you want a cave experience without the tour buses, this is a good choice.

About an hour from the house, near Brtonigla in northwestern Istria.
