I was in Vaals earlier this year and one of my friends really wanted to see the three country point. It was quite boring... It is just a mark in the woods. And apparently it's not even in the correct place (I believe there was a smaller mark that marks the actual border point). You can climb a tower if you don't fear heights (the steps are see-through rosters), which gives some nice views but not so spectacular that it was worth all the time to get there.
Have fun!Edited: 12 August 2015, 10:04
