Top 10 Mines in Indonesia: Sawahlunto, Grasberg and the Tin Islands
Indonesia is one of the world's largest mining nations — copper, gold, nickel, tin, coal — and its colonial and contemporary heritage is sprinkled across the archipelago.

Grasberg Mine, Papua
Freeport-McMoRan's vast copper-and-gold complex, one of the largest in the world; access is restricted but the scale defines modern Indonesian mining.

Planning your route
These ten sites span very different climates, languages and accessibility levels. Group them by region, allow a full half-day for each underground descent, and remember that in the tropics underground workings are often warm and humid rather than cool — check conditions for each site in advance. Local guides are often retired miners — their commentary is the single best part of any visit.
