Most visitors enter on a 30-day Visa on Arrival (VoA), which costs IDR 500,000 (approx. USD 35) and can be extended once for an additional 30 days.

While credit cards are widely accepted in hotels and restaurants, cash (Indonesian Rupiah) is essential for local markets, entrance fees, and small warungs. ATMs are widely available.

Ensure you have a local SIM card (Telkomsel has the best remote coverage), keep offline maps downloaded, and always carry sufficient drinking water.
