Shilla Millennium Park is woefully under-promoted. Partly because it's a relatively new theme park - but mostly because Gyeongju is as a popular budget backpacker destination and a family-friendly historical theme-park doesn't really appeal to the Lonely Planet/backpacker set.
Shilla Millennium Park has a lot of what you'd expect from a standard historical theme-park - trying to make history come alive for groups of school kids on field trips.
And it works!
There are lots of re-created sets and exhibits showing Shilla culture and how people lived in the Shilla Kingdom. The most impressive set is the palace used in the filming of the Korean drama Queen Seondeok. Most everything is labeled in English and some exhibits had extensive English descriptions.
There are performances in the park - we caught the fun Hwarang show with horses and swordplay. Facilities are excellent - including a nice "traditional" cafeteria. For kids, there're fun things like fountains, caves to explore, waterfalls, and several opportunities for crafts. Our kids made replica Shilla crowns, axes, fans, mirrors, among other things.
To get here, take the #10 bus to Bomun Lake (or if you're coming back from Bulguksa/Seokguram, take the #11 bus). Get out at the Hilton bus stop, then walk east.
If you're an independent budget traveler who's in Gyeongju for sight-seeing and hiking, then spending the money for tickets to Shilla Millennium park probably isn't to your taste. But if you don't mind spending the money to get a little fun history - and DEFINITELY if you have children - then Shilla Millennium park makes a great half-day outing.
