Korean Cultural Heritage website for details.
I imagine the surrounding vicinity rather than the tomb itself gives reason for the locals to visit. Smack dab in a very apartment-heavy neighborhood is a very green and walkable area. One walking course goes around Jeongneung's land, and takes about thirty minutes. If it was a little closer to my school, I would visit often to go for jogs. Peaceful, if a bit hilly, Jeongneung can be seen in about an hour.
Jeongneung was a bit difficult to find... here are the directions from Visit Korea:
|In front of exit 6 of Sungshin Women's University station
(Donam station / Seoul Subway Line 4), take city bus No. 1012, 1014, or
1212 and get off at Arirang Market. Walk 5-10 min.|
