Urner Mine­ra­li­en­tage

The long-established mineral fair in Altdorf lies at the heart of one of Switzerland's most important crystal regions. Local crystal hunters show their latest finds from the Alps, alongside minerals, gemstones, fossils, books and collecting supplies – a meeting place for collectors and experts, with a special exhibition of rare pieces from private collections that changes every year.

Admission: CHF 8, children up to 16 free; the ticket also gives free entry to the mineral museum in Seedorf.
