Beaches, Gamcheon Culture Village, the markets and Haedong Yonggungsa are all free. These are the only things on our 3-day route where booking ahead actually helps.
1. Mobile data
Install a Korea eSIM before you fly, or pick up a SIM at Gimhae Airport. You'll want maps and translation from the moment you land.
Korea eSIM options (Klook)2. Airport transfer (if you land late or travel as a group)
A fixed-price driver is worth it after about 10:30 pm, or for 3 to 4 people with luggage. Otherwise the light rail and metro are fine. See Airport to Haeundae.

The one ticket that really sells out, especially at weekends and sunset. Priced per capsule for 2 to 4 people.

Worth it only if you plan several paid attractions in 24 to 48 hours. The physical card also works as a rechargeable transport card.
Visit Busan Pass (Klook)5. A guided day (optional)
If you'd rather not handle bus transfers, a day tour covers Gamcheon and the west side, or the east coast and the temple, in one go.
