Jangheung county---which still has the slogan "Powerful Jumping! Green Jangheung"---will hold the Jeongnamjin Aqua Festival (정남진물축제) from July 29th through August 2nd. This is the second of what plans to be an annual festival, and you can browse photos via Naver. There's a small program online as well as a festival map. The booths look to be open from 10:00 to 18:00, and there are a number of concerts planned nights, including groups like Girls' Generation, SG Wannabe, and a group called Gary Goldsmith, who shares the name of an apparently-notorious uncle of Prince William's girlfriend. One of my favorites, Bobby Kim, will be there on the 29th.
I'd like to visit Jangheung for this, and not just because there's a semi-nude photography contest on the 1st and 2nd. I've passed through town a number of times, because it's the next one over from Gangjin, where I lived for a year. Shortly after I left they completed a nice park along the river in town, and while I can't vouch for the quality of the entertainment at this festival, I'd like to get a look at this park, the Tamjin River Ecological Park (탐진강생태공원). Here's a photo from the 전광일보:
It's been a while since I've been in a small town, and I guess Jangheung qualifies. The county has 43,703---1/13th the population of Gangnam-gu---and with 15,622 people, the town of Jangheung-eup is slightly larger than Gangjin's county seat. Something that also may be worth a visit is the Water Culture Park (장흥물문화공원)---called a Waterium on the side of the building---built near Jangheung Dam (장흥댐) in Busan-myeon some 9 kilometers north of town. Conveniently there's a site called 장흥댐뉴스 that provides some interesting information and pictures. There is a "Slow City" in Jangheung, too, and a few sites used as filming locations for movies and soap operas. I suppose the most "famous" thing in town is the Saturday Market (토요시장), held each Saturday morning a short walk from the bus terminal. The events at the festival are likewise a short walk from the terminal. Buses run regularly from Gwangju, Suncheon, and practically everywhere else.
If you're still looking for incentive to visit, why not take the county's magistrate word for it?
Jangheung that starts the running with nature protecting - as it is - and all county peoples' infinite development possibility and power !
You can, um, learn a lot more about last year's semi-nude photo contest here and here, two links that aren't safe for work unless you work at the Chosun Ilbo. There's an entrance fee of 40,000 won, and you can get more information from the Jangheung Photo Club.
