I ordered a ticket when I arrived at the gold museum. Prices for traveloka are cheaper than buying directly on the spot. For very good knowledge, but unfortunately when walking around the museum there is no gold processing performance because the engine is broken. So it's just photographs. The museum is not too big, to get around and photos take about 20 minutes. There is also a souvenir shop that sells souvenirs, gold and silver accessories, and precious metals.
