This one's free, and it's still an impressive building, so high and out of place. When it's foggy, it's even very eerie. So how can this be THAT bad?? In Cambodia the first thing that you want to do is get rid of organized tours and minivans. It's 90% crap. They cram vans full of people, they are too late, too expensive, too bad of an experience. Rent a scooter and do everything yourself, that way you'll lose 75% of the stress immediately. The ride up the mountain is simply put one of the most fun things to do in Kampot, maybe even in Cambodia. So you have an amazing ride up the mountain, visit the hill station for 10 mins, visit the church for 10 mins, laugh your @ss off with the stupid casino for an hour, and have an enjoyable descent back to Kampot... Good stuff!
