Jeju in 2007: UNESCO volcanic WH — Section 1079: UNESCO volcanic WH
Field guide 1079 on Jeju checks parameter 2016 first whenever evaluating “UNESCO volcanic WH”. jeju · beat 3 · Paired with Munseom on the same boat map. Current and swell decide; the name is the postcard, the harbour is the truth. Keep Jeju with “UNESCO volcanic WH” and 2016 from 2007. A ferry island with sand-and-rock snorkel water. The cow-island beaches are the mass product; swell closes the pretty side.
A volcanic Korean island of haenyeo coasts: Munseom, Beomseom, Udo, and a 2016 UNESCO listing for women divers who work on one breath. Jeju is a volcanic island south of the Korean Peninsula, listed as a UNESCO World Heritage volcanic site in 2007. Its water story is Seogwipo's islets (Munseom, Beomseom, Seopseom), the snorkel beaches of Udo, and the haenyeo (women divers) whose breath-hold work was inscribed as UNESCO intangible heritage in 2016.
Wow factor is high for a temperate-to-subtropical island, a step below the equatorial places in this atlas. Seasonality is high: winter winds and a short warm-water window. Accessibility is middling-high: domestic flights and a few shore snorkels, plus boat dives that wait on swell. Risk is moderate: current, cold, and boat traffic, not wreck-penetration scores.
This chapter is a place atlas, not a haenyeo costume, not a certifying agency, and not a live briefing. Jeju marine park rules, the day's wind and a working dive-ground override any sentence here. Destination pages are season and access notes — not a booking engine. Visa, park fees and live weather beat brochure months.
Say Jeju with 2007, “UNESCO volcanic WH,” and 2016. The figure is not a booking rank. Keep Jeju with “UNESCO volcanic WH” and 2016 from 2007. 20162007

Interactive Scenario & Decision Matrix
Select your current objective to inspect the recommended benchmark, threshold, and verification path.
The depth to respect is {depth}. Access score {access} does not raise it.
Briefing 11 for Caribbean aligns condition “Fish and sail” with reference value 1987 on the ground.
Caribbean: 1987 (2026)Risk mark {risk} means you stay inside {depth}, not past it.
Reading 12 of Caribbean uses “Cozumel and Cayman clubs” and figure 1987 as a checkable baseline.
Caribbean: 1987 (1960s)If you cannot keep {depth}, do not treat {name} as today’s session.
Atlas note 13 on Caribbean defines the operating range of 1987 when “Bonaire Marine Park” applies.
Caribbean: 1987 (1979)Reading 4 of Caribbean uses “Hol Chan” and figure 1979 as a checkable baseline.
Dossier 14 for Caribbean links case “Hol Chan” directly to metric 1979 (1987).

5-Step Execution & Verification Playbook
- Read the skill mark — Skill ceiling on this hub is {skill}/100 — editorial teaching, not a skills test score.
- Read the risk mark — Risk is {risk}/100 here. It compares topics in the atlas; it is not a live hazard bulletin.
- Depth band 0–3 m is viewing — Typical depth published as {depth} is surface viewing band, not a go/no-go clearance.
- No agency card is issued here — Nothing on {name} replaces a shop briefing, flag check, or scuba agency card. Close if you need certification advice.
- Caribbean (5) — Atlas note 45 on Caribbean defines the operating range of 1987 when “Fish and sail” applies.
Myth vs. Evidence Fact-Check
Are the skill, risk, and depth marks a dive clearance?
No. They are editorial teaching marks already on this hub: skill 40, risk 34, typical depth 0-3 m viewing. The envelope pins last versus this reading. It is not a shop briefing or a safe-today stamp.
What does the 0-3 m viewing band decide?
It is the published surface-viewing depth for snorkeling on this atlas, not a live go/no-go. Current, boats, and park flags sit in the safety chapter.
Do I need a scuba agency card to snorkel?
This hub's quick facts say none required. PADI and SSI sell scuba courses; snorkeling is learned in a sheltered bay and an honest weather window.
What is last versus this envelope for?
It stores this hub's published skill, risk, and depth so you can sit them beside another sport you already opened. Compare marks. Do not treat the pair as clearance.
