Jinhae is a reasonable size town (pop- 172 000) in South Gyeongsang province (Gyeongsangnam-do), once its own city however recently absorbed into the neighboring city of Changwon. It is known primarily for its large Korean and American naval base and its Cherry Blossom festival held every year approximately in early April. There are possibly more cherry blossom trees to be seen here than in any other location in Korea, and although there are a couple of popular, groomed places for visitors to see them, you can find them strewn throughout the hillsides surrounding the town. Aside from the cherry blossoms, the city contains many of the features you'd expect to find in a Korean town, with restaurants, shops, supermarkets, bars, a traditional market, noraebangs etc.
The easiest way to get to Jinhae is bus. There are several services a day from Seoul's Nambu Terminal, taking around 4 hours and costing around 25000\ and several from Daegu. Buses to/from Busan run every 15 minutes, cost 5100\ and take 45 minutes to an hour to reach Jinhae. These buses start at Seobu terminal in Sasang (subway line no.2/Busan-Gimhae light rail) and call at Hadan (subway line no.1) before heading to Jinhae. There is a couple of train stations in Jinhae (Jinhae and Gyeonghwa) although trains only run here from Changwon during the festival).
Another option is to take a bus or train to Changwon, and then take local bus 151 to the destination. For this, it helps to know some Korean, and to have keen eyes to find the bus stop, which is located to the right of the entrance of Changwon bus terminal and around the corner. If you choose this option, you will want to get off at the Jinhae high school bus stop.

The main thing to see in Jinhae is the cherry blossoms every spring. There are two primary locations that visitors go to see them. One is the train tracks just next to the high school that is a major bus stop. If you wait long enough, trains will come through this spot at a very low speed, making some idyllic photo shots as they roll through the cherry blossom lane.The other location is at a river in the downtown section of Jinhae, located a 30 minute walk north of the bus station. At this location there is a small stream lined with cherry blossom trees on both sides that tourists are sure to be flocking around.
Good views of the city can be had from the tower in Jehwangsan Park located in the centre of the town near Namwon Rotary, to reach the tower one must climb up the 365 steps that lead to the top of the hill, alternatively there is a monorail car running up the hill, to get to the top of the tower you can ride the lift or take the stairs.
Jinhae's Marine Park located near the massive STX shipyard is a popular attraction. Here you can visit a museum dedicated to the ROK Navy featuring the retired Gangwon ship, a Marine Life Theme Park, robot exhibits and the Solar Tower. The park can be reached by bus (303 and 306) from Namwon Rotary, get off at Myeongdong or by taxi.
Hire a bike. There are plenty of bikes available to hire around the city for a low cost, although hiring one may be complicated if you are unable to understand Korean and lack a Korean telephone number.
Take a stroll/cycle along the seafront (known as Jinhae-ru), on a Saturday evening you are likely to encounter various performers and buskers. Good views of the bay can be had from the pavilion.
If feeling energetic, there are numerous hiking trails in the countryside surrounding the city. Good views of both Jinhae and parts of Changwon can be had from Anmin Ridge (Anmingogae). To reach the ridge, it is best to start at Gyeonghwa Station and head towards the mountains, there are numerous paths leading to the ridge.
