I drove to Tachov recently to check out a cool look out tower and to get a great view of the city. In Czech, it's called Rozhledna na Vysoké u Tachova. I don't speak Czech, but we can have fun and write that out. Anyway, here's the view I discovered:
Tachov is a 1 hour drive from Plzen, but the tower view was totally worth it. There isn't much else to the town. There is a super small center/square, but that's about it. Never stop exploring!
