After a good workout to get to the tower, you are treated to a 360 view of Seoul. I would highly recommend flat, comfortable shoes as you have to walk a high incline to get to the tower for about 8 minutes.

We like the cable ride, seeing everything below can really thrill my 9yr old son,nice scenery everything is lightly covered with snow..( we live i a tropical country) i wouldn't say the place is excellent but the whole experience is.. At least the cable ride makes it different from tokyo tower and sidney tower..both in the middle of the city without mountains , greens.. Would be better though if you have a rough ramp or an elevator/ escalator for infants with stroller..indeed tiring to carry both the baby and the stroller.

The North Seoul tower is an excellent way to get good views of the city. We first travelled to Myeong-dong station (line 4 light blue) & exited on #3 which by luck put us right at the transfer bus ( free) up to the cable car ride to the tower. You just have to wait untill the bus is full before it goes. It runs every half our, so just wait if you think you have missed it. It is a green & yellow mini bus. The cable car is one big car that takes about 20-30 people (which is well legal) & it's KRW8000 for a return trip each adult. Once you arrive at the top of the cable car ride it's a reasonable climb ( a million steps according to my missus) to the tower. By going this way there is no disabled access but you can access the Tower by the Seoul City Tour bus if you are getting around in a wheel chair.
Once at the Tower there is a variety of things to look at even if you don't want to go up into the viewing platform. There were performers of different sorts, viewing platform, & shaded trees to sit under. The entrance fee to the top of the tower is KRW9000 each for an adult. I thought it was KRW20000 each but when i bought the tickets it was only KRW18000 for both of us-bargain!!!. The ride to the top of the tower is quick & there is a corny video to watch to take your mind of the ride.
The view form the tower is quite good but i would suggest being there on a smog free day or you won't have much to look at. Even when we went it was a very nice day but visibility was about 5-10KM. Plenty of trinkets to buy & there is the usual super imposed photo in front of the tower. Quite easy to dodge that one as we didn't speak Korean.You can spend as much time as you like up there & the ride down is as quick as going up.
When you're at the bottom of the tower, check out the padlocks of all the gestures of love. Quite impressive really.

I always enjoy towers in the cities that have them and this one is top end. One large hill so high high high. Cable car up to base is alot of fun and in a park area so nice green start. Go early or crowds start to grow, but if so, go 1 flight stairs down to departure area where much less people. Views are totally wow and city forever.
