Quick answers
Which local rescue or training agency should I check first?
Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
Udo?
A small island east of Jeju (the name means cow) with beaches and shallows used for snorkelling, including Hagosudong-type sand. A ferry, not a liveaboard.
Who are the haenyeo?
Jeju women who harvest on breath-hold, a living work culture listed by UNESCO in 2016. Tourists should not copy the work or treat a dive-ground as a playground. See freediving and Jeju's culture chapter.
Is Jeju tropical?
No. It is a warm-temperate to subtropical island. Visibility and soft-coral colour are seasonal, not a Maldives lagoon.
Seopseom?
Another Seogwipo islet on the same boat map as Munseom and Beomseom, often mentioned in the same brief.
Jungmun?
A resort coast with a beach and, nearby, the Daepo jusangjeolli (columnar joint) shore: geology as much as a snorkel. Swell closes it.
Haenyeo work is older than tourism. As a visitor destination Jeju adds a 2007 UNESCO volcanic listing, a 2010s Seogwipo dive-shop cluster, and a 2016 heritage listing that made the women divers a public sentence, for better and worse.
The history is a working lung, then a ferry ticket.
