I would like to recommend to prepare you phone battery well. Never map because Korean doesn't use Google maps.

BUS

My local friend recommended Wave-On Coffee shop. Location is not in town but you will be satisfy as I am. The beach is very clean and water color is cystal clear. So far this place is the most favorite for Korea's beach. I took bus no. 180 from Haeundae beach directly to cafe. It took 1 hour 30 minute. You can take subway also with the shorter time but need transfer. At the cafe we need to buy one drink to be able to enter so I bought 1 coffee and 1 sweet. The day I visited wind is very strong so I took blanket (which cafe prepare) I spent time at their around 2-3 hours by looking around, took pictures, vdo and charge my phone ( as you know Korea we can charge phone everywhere ;p ) and Cafe has 3rd floors. If you have spares time just visit this cafe I'm strongly recommend to visit Map: [NAVER Map] Wave On Coffee 부산 기장군 해맞이로 286 https://naver.me/50oMegvd
