Busan is a big city in the south east of South Korea. It has a unique feeling to other places I have visited. Not as clean as Japan but not as dirty as China. Not as expensive as Japan but not as cheap as China. South Korea seems to be in the middle of both.
Firstly
Transport to Busan
So there are several ways to get to Busan. A Train from Soeul, a plane from Tokyo, and a boat from Fukuoka. Japanese people visit Busan for a day trip by boat!
The ferry port is located in the centre of the city and is easy to access. So I guess if you really want to you can visit Fukuoka. (But please check and book in advance before arriving at the ferry terminal. with direct ferries)
On a side not if you get to the airport early when departing don’t expect much in departures.

Songdo beach
I visited the beach at night, but it was lit up well. There is a cable car that runs between the beach and Amnam park which gives you great views of the beach and the cityscape. There are plenty of restaurants and I’m not going to lie I didn’t do much here. Other than go and soak up the sea air, and walk across the sand. It was very pleasant π .

Haedong Yonggungsa
Haedong Yonggungsa is a temple located on the coast of South Korea. North of Busan “easy to get to”. I say that in quotes because I got lost. It turns out you can get buses directly to it from Haeundae Beach, which I didn’t know about.
The original temple was built in 1376 but was destroyed by Japanese invaders.Β It was rebuilt in the 1930’s. There are a lot of hidden random things to do there.
Throw a coin into the bucket and have your wish come true. Buy a pray piece and put them somewhere around the temple. Locate the prefect spot to feel and taste that fresh sea air.

Haeundae Beach
Good standard beach resort. Food and goods market around, big skyscrapers and christmas lights!
The best part of it wasn’t the sea life centre but the free foot spa next door! The water was so hot. (When I was there it shut at 5pm so better get there early to enjoy the hot spring).

Gamcheon Culture Village
Gamcheon was full of different arts and crafts and places to eat it would take a long time to explore the whole village even if you lived there I’d recon you’d find something new everyday. It’s really easy to explore and find things to do. Lots of craft shops which will teach you local crafts. Stick to the main route if you’re pushed for time.
Shopping and Extra
Jagalchi Market
Fish market where you can pick your own fish which you can take to a restaurant and they will cook it for you. (I didn’t do this)
Gukje Market
Multiple goods market where you can find a bargain.
