What to buy (simple decision)
- Short visit / light riding: a smaller number of rides may be enough.
- Full-day sightseeing: a day-based option can reduce friction.
- Multi-day trip: consider a multi-day option so you stop thinking about tickets.
Tip: your best choice is usually the one that avoids re-buying mid-day.
How to use OPUS smoothly
- Load your pass before your first big outing.
- Keep the card accessible so taps are quick at gates/buses.

What’s the easiest pass choice for visitors?
Choose the option that matches your trip length and avoids re-buying during a full day out.
