When to Visit Busan
Spring
Spring brings cherry blossoms to parks and streets across the city, plus mild weather that’s ideal for hiking the surrounding mountains or strolling the coastline. It’s also when you can catch cultural events like the Busan International Film Festival or the Lotus Lantern Festival.
Summer
Warm temperatures and plenty of sunshine make summer the time to hit Busan’s famous beaches, like Haeundae and Gwangalli — water sports, beachside cafes, and lively nightlife included. Expect higher humidity and occasional monsoon rain in July and August.
Fall
Comfortable temperatures and vivid foliage make fall another great option, especially for hiking, biking, and visiting cultural sites like Beomeosa Temple and Gamcheon Culture Village. Don’t miss the Busan International Fireworks Festival in October over Gwangalli Beach.
Winter
Busan’s winters are mild compared to the rest of South Korea, though it’s still the low season. Cooler temperatures mean quieter attractions and cheaper accommodation — and if your timing lines up, winter rolls right into the Jinhae Cherry Blossom Festival in early spring.

How to Get from Seoul to Busan
On my trip to South Korea, I made a point of visiting Busan — and I’m glad I did. Figuring out the best way to get there can feel a little overwhelming, so I tested a few different methods myself, traveling one way by one method and back by another, to give you the clearest picture. Here’s a detailed look at getting from Seoul to Busan by train, plane, and the highway.
Train from Seoul to Busan
The easiest way to get from Seoul to Busan is the high-speed rail system. The Korail (KTX) covers the distance in just two and a half hours, reaching speeds around 300 mph — similar to Tokyo’s bullet trains — so you’ll watch the landscape fly by.
Trains run throughout the day, with the first departing Seoul at 5:15 am and the last at 9:00 pm. One important thing to check when booking: make sure your ticket is non-stop. Some trains make additional stops or run as local services, which can turn what should be a short trip into a 5-hour journey. Worth avoiding entirely.
The KTX offers two classes. First class gets you larger, more comfortable seats with extra legroom, enhanced reclining, and often complimentary snacks, drinks, and newspapers, plus individual power outlets and reading lights. Economy class is more basic, but for a trip this short, I found it more than enough.
Booking online can get confusing, since several third-party sites charge more than booking direct. Book through Korail’s official site to avoid the markup. Economy tickets run roughly 48,000–70,000 KRW; first class runs about 60,000–90,000 KRW depending on the route. If you’re taking the train more than once on your trip, look into the Korail Pass for unlimited rides on trains and the subway.
Flying from Seoul to Busan
A domestic flight is another solid option — the flight itself takes only about an hour. South Korea has several domestic carriers, including Air Busan, Jeju Air, and Jin Air. As an example, I found a one-way Jin Air ticket for just $25 USD. Being flexible on your departure date helps you find fares like that.
A couple of things worth knowing before you book a flight. First, factor in the distance to the airport — both Incheon and Gimpo International Airports sit about 45 minutes to an hour from central Seoul, which can actually make flying slower overall than the train once you add transfer time.
Second, most of these carriers are low-cost airlines. That means seat selection and checked luggage both cost extra. Carry-on policies tend to be more generous than what you’d find in the US, but if your bag goes over the weight or size limit and has to be checked, fees add up quickly. If you’re traveling light and find a good fare, flying is a genuinely viable way to get from Seoul to Busan.
Seoul to Busan via the Highway (Bus, Rental Car, etc.)
The last option is traveling by highway — I’m grouping bus and rental car together here since they share similar pros and cons.
Driving from Seoul to Busan without stopping takes about four and a half hours, though traffic can stretch that out. My own trip, via tourist bus, took just over 6 hours, including a 30-minute rest stop for food and a bathroom break.
Bus tickets run around $20 USD, roughly half the cost of the train. It really comes down to whether you’d rather save money or save time. The bus itself was comfortable, with large reclining seats and air conditioning, but given the choice again, I’d pay the extra for the train.
If you’re renting a car, note that South Korea requires an International Driver’s Permit. It’s easy to get in the US — just bring the required forms and photos to your nearest AAA; no test required. Also budget for tolls, since it’s an express highway and you’ll typically pay on exit.
Final Thoughts: Getting from Seoul to Busan
There isn’t one single best way to get from Seoul to Busan. For me, it’s the train — but everyone has their own reasons for choosing differently.
