Everyone takes the funicular up petřín hill but the walking path through petřín park is much more rewarding. Winding gravel paths through old growth trees with glimpses of the city appearing between branches

The lookout tower itself is touristy but the journey up on foot gives you time to really see the neighborhoods below. Brings back that feeling of discovering a city organically instead of being transported directly to viewpoints

Funicular costs 60 czk round trip when walking is free and honestly more interesting. Save the money for coffee at the top
