Mineral collecting in Hungary’s most stunning landscapes is back for 2026. Expect hikes through mountains and valleys, big‑sky scenery, rare finds, and hands‑on discovery for adults, families, and kids. Guided mineral and fossil experience tours run on scheduled dates across multiple towns and sites, and groups of more than 10 can book custom dates for tailored collecting adventures.
When and where
The season kicks off on 2026.05.01 (Friday) in Pilisjászfalu, ZIP 2519, with the headline outing: Mineral Collecting Tour Pilisjászfalu – In Search of UV‑Active Calcites. Eighteen tour photos showcase what to expect, from rugged quarry benches to glittering finds.
What you’ll find
Every Pilisjászfalu trip is a surprise hunt across the abandoned quarry’s stepped levels, where distinctive calcites appear in waves—sometimes sharply crystalline, sometimes thick and massive. Most specimens are UV‑active and fluoresce vividly under both 365 nm and 395 nm UV‑A light. Collectors can target crystal‑surfaced and massive calcites ranging from pure white to rusty red, pea stones and dripstone formations, plus the signature “wolf‑tooth” calcites. Guides lead the search across multiple quarry tiers to uncover the finest pieces together.
