I was really glad i availed of this transpo service. Driver Wu was great. He bought the tickets for us and even accompanied the group to the top so he can assist with the translation of the attendants’ instructions/directions and even offered to take pictures without being asked. While it may be more expensive than using public transport, the ride was comfortable and we saved a lot of time and energy and allowed us to be back in Myeongdong early.

⭐⭐⭐⭐⭐ Such a fun day out! Had the best time on this tour! Super worth the money and packed with so many cool spots. Huge thanks to our guide, Suki—she was awesome! She speaks fluent English and Mandarin and shared so many fun facts throughout the day. Feeding the seagulls on the ferry was definitely a highlight! She was also smart enough to flip the schedule so we hit the Ganghwa Luge first thing in the morning, which saved us from the crowds and the midday heat. The bus was super comfy and the ride was really smooth too. 10/10 recommend if you're looking for an easy, fun day trip! Thanks for everything, Suki!

Our tour guide, Roger, was incredibly professional! He contacted us via WhatsApp the day before the activity to reconfirm the itinerary. Roger took many photos for us at different attractions, which we really appreciated 👍. Although the weather on the day of the tour was not as expected, with heavy rain preventing us from doing the luge as planned, Roger immediately changed the indoor itinerary. In the morning, we visited Inspire, which has a playhouse and casino, and both adults and children were very satisfied 👍. The rain stopped in the afternoon, and we successfully completed the seagull feeding and cycling activities. The biggest surprise was driving a private car directly onto the boat for feeding the seagulls! 🤩

Ren was a wonderful guide and driver. He was so friendly and helpful throughout the whole process from before the tour and during and even encouraged us to come back and again and to contact him when we are next in Seoul. Because the other tour group canceled, my friends and daughter got a private tour by default, so Ren picked us up from our hotel and dropped us off where we wanted to go at the end. The tour itself was so much fun and educational. We had the best time!!! The glass skywalk was scary (made me think of that glass game on Squid Games) but had amazing views. The cooking portion was interesting and sooooo very delicious. Ren actually went up and down the luge with us because he wanted to make sure that we were safe and had a good time. It was the perfect amount of spots to visit and time to get a good taste of what Seoul has to offer. We definitely want to come back and take some more tours, hopefully with Ren!!! Thank you!!

Our private car service experience was truly excellent; the entire service process exceeded our expectations! First, a big thank you to Tiina, our contact person. From the initial inquiry and booking to confirming the itinerary before departure, she was incredibly friendly, patient, and responded quickly. She meticulously assisted with and arranged all our questions and itinerary details, making us feel very reassured even before we left. Even with some last-minute requests, she did her best to help, showing that she genuinely wanted us to have the best travel experience. Our driver, Kim, was also very punctual and friendly on the day of the trip. He drove smoothly, making the entire journey comfortable and the pick-up and drop-off process very seamless. We will definitely choose this company again for any future private car service needs!

We booked this tour because we had an early arrival and wanted to male full use of our first day. I missed seeing that this starts at 9AM hence we waited for bit. our guide Gavin arrived on time and was a very good guide. The tournis quite flexible (because we asked to go home once we could check-in to rest and skipped 1 stop). He also recommended really good restaurants (we were looking specifically for ganjang gejang recommendations). Also liked that the tour for Kimchi museum has several tour guides specific to the nationalities of the guests.

Thanks to Will for taking care of us throughout the trip. He was incredibly thoughtful and responsible, even adding side dishes for us during meals, haha! Definitely recommend him! I highly suggest doing the rail bike an extra time (it's an additional 10,000 Korean Won in cash for one extra ride). We had so much fun, even our 3-year-old loved it! It was a great itinerary.

What to know before visiting Incheon

Quick snapshot of Incheon and what travellers book

Incheon draws visitors for tours, events and attraction passes, with sizable bookings also for massages and family-friendly playgrounds. Demand on Klook has a clear yearly rhythm, with busy spikes in spring and much quieter late-summer months.

Best times to visit and how prices move

Klook booking data shows demand peaks in April and drops to a low in August and September. Prices on Klook are unusually flat across the year in USD, so you won’t see major price swings even when demand rises or falls. For lower crowds and a quieter experience, consider visiting in August or September when demand is at its lowest; for peak-season atmosphere and the liveliest events, April is the high point. Because prices stay steady while demand changes, decide by whether you prefer energy and events or smaller crowds rather than chasing cheaper tickets.

Tips for travellers from the Philippines

Filipino travellers typically book around two weeks ahead, with many final bookings made within about five days of travel and some planning up to about a month in advance. If you want flexibility, many experiences can be arranged a few days before arrival, but for popular tours or shows in April it’s wise to secure reservations earlier. Use Klook to compare tours, event tickets and attraction passes so you can lock in the experiences that matter most to you.
