Idrija

Idrija is a small town wedged into a forested valley west of Ljubljana, built around what was, for almost five hundred years, the second-largest mercury mine in the world. The mine opened in 1490 and closed in 1995. In between, it produced something like 13 percent of all the mercury ever mined on Earth, made Idrija the second town in the Habsburg lands to get electric street lighting, and produced a parallel craft tradition — Idrija lace, taught in the world's oldest continuously running lacemaking school (founded 1876) — that has long outlasted the mine.

The two together — mine and lace — were inscribed on the UNESCO World Heritage list in 2012 as part of a transboundary site shared with Almaden in Spain. Walking the town, the inheritance is everywhere: miners' houses on the slopes, the Gewerkenegg castle that the Habsburg authorities used to administer the mine, the surviving water-driven Kamšt pump that lifted mine water until the 1940s. The old kilns that roasted mercury ore still stand in Hg Smelter Park.

What makes Idrija worth a stop, beyond the obvious, is that it has not turned itself into a museum. The lace school is full of teenagers. The Kendov Dvorec hotel is an actual hotel, not a stage. And the local žlikrofi — small pinched-pasta dumplings filled with potato and bacon, given EU geographical indication status — turn up on every restaurant menu without ceremony.

May, June, September and early October are the most pleasant months — long days, walkable trails into the surrounding Idrija Geopark, and the cultural calendar at its fullest. The Idrija Lace Festival in late June is the year's anchor event, when the lacemaking school hosts open classes and a competition draws makers from across the region. July and August are warm but never crowded; the mine itself is at a constant 12°C and a welcome retreat from heat. Winter is quiet and beautiful — the Geopark trails take on a quite different character — but the smaller restaurants and several guesthouses close from December to mid-March. Christmas markets are modest and worth the visit if you happen to be in the region.

From Ljubljana the route is straightforward by bus: Arriva-Alpetour runs a regular service from Ljubljana to Idrija (around one hour and fifteen minutes), several times a day on weekdays. The nearest railway station is Logatec, on the Ljubljana–Postojna line, with a connecting bus to Idrija (about thirty minutes). From the coast or Italy, the most efficient route is via Postojna with a change. There is no direct train to Idrija — the post-industrial irony is that the mine's own narrow-gauge railway closed long before passenger service ever reached the town. A car is not required; the town centre is small enough to cover on foot, and the Geopark trails start from the edge of town.

Kendov Dvorec, in the hamlet of Spodnja Idrija five minutes down the valley, occupies a fourteenth-century manor with rooms furnished in regional antiques and is the most considered place to stay in the area (to verify rates and operation directly). In Idrija itself, the Hotel Jozef is a compact business-style hotel by the bus station with reliable rooms and good local food in the restaurant. Pension Barbara, named after the patron saint of miners, is a family-run guesthouse with around a dozen rooms. The tourism office on Mestni Trg keeps a current list of farm-stays in the surrounding villages, which are the sensible choice for a longer visit or if you intend to walk the Geopark trails systematically. Avoid the roadside motels on the Tolmin–Ljubljana road; the centre of Idrija is more interesting.

The dish to order is idrijski žlikrofi — small dumplings folded in a distinctive hat shape, filled with potato, onion and bacon, traditionally served either in broth or with bakalca, a slow-cooked lamb-and-vegetable ragout. They have held EU TSG status since 2010. The restaurant Gostilna Pri Skafarju, in the town centre, makes them the way the lace teachers' mothers did. Kendov Dvorec serves a more refined version on its tasting menu. Beyond the žlikrofi, the local kitchen reaches for whatever the Idrija forests provide — porcini in autumn, venison in winter, freshwater trout from the Idrijca year-round. Drink the local beer (Pivovarna Human in Spodnja Idrija) or the wines of Vipava just to the south-west. The Sunday lunch at Gostilna Mlakar is the local institution to know about.

Take the Anthony Main Road mine tour — Antonijev rov — the oldest preserved section of the mine, which descends through five centuries of mining technology in about ninety minutes. Walk up to Gewerkenegg Castle for the municipal museum (the mercury rooms are the heart of it, the lace rooms an essential counterpoint). Visit the Idrija Lace School during term to see classes in progress. Walk the Kamšt pump and the Hg Smelter Park along the river. The Idrija Geopark — wider than the town — has a network of marked trails through the karst landscape, the most rewarding of which climbs to the Wild Lake (Divje jezero), Slovenia's first natural monument. The Klavže — sixteenth-century water barriers used to float timber down to the mine — are a quiet half-day walk.

Language: Slovenian; English in tourism contexts; Italian and German common with older residents. Currency: euro. Plug: European type F/C. ATMs in the town centre; cards accepted in restaurants and hotels, cash useful at smaller bars and the lace shops. The mine tour requires a guide and is booked at the Anthony Main Road ticket office or in advance online. Mobile coverage is solid in town and patchy on the Geopark trails. Nearest hospital: Idrija (small) and Ljubljana (full).
