Advice given by a friend to do this tour, and although I thought it was expensive, it ended up being really worth it. We did a full day tour, booked in advance over the internet (as advised) and paid $85 each. Booking was easy and if you break it down into individual components, I guess it was expensive. But ... what you can't put a monetary value on is the experience. At the Joint Security Area there is a feeling of theatrics, but perhaps that is because we have always lived in peace and harmony, never feeling the threat that is part of every day life for those there. There was lots to learn and new understanding of how things are for Koreans, particularly those in the north. If you are in Korea, plan ahead and do the tour. Be mindful of dress code and the need to carry your passport. And we have to be grateful to those UN forces who help to keep the peace. Lets hope Unification isn't just a dream but a future reality.
