Udo Island
Take a 30‑min ferry from Seongsan (Jeju) and spend a day biking or bus‑touring Udo; no overnight stay needed.
Udo Island is a 3.5 km offshore lava plateau with beaches, peaks and a sausage street. A ferry from Jeju runs every 30 minutes (9:00‑17:00). The island is small enough to see by bike (13 km loop) or the 1,000 won tourist bus, so one day is sufficient.

Etiquette
- Greeting: A slight bow with a 'annyeonghaseyo'; handshake with the right hand, left hand touching the right forearm; avoid: Hugs and cheek kisses with people you have just met

- Handing things: Two hands for money, cards, gifts and drinks; avoid: Passing things with one hand to older people
- Subway: Quiet voices, bags off seats, queue at the marked lines; avoid: Priority and pink pregnancy seats, even when empty
- Home visit: Shoes off; bring fruit or a boxed gift; refuse once before accepting; avoid: Writing names in red ink — it is used for the dead
- Temples: Covered shoulders and knees; bow at the main hall; avoid: Stepping on thresholds; loud talk; pointing at Buddha statues
- Numbers: Know that 4 is unlucky; buildings may show F instead of a fourth floor; avoid: Giving gifts in sets of four
