Yes, that is what we like. Culture, architecture and nature.

The sun can be dangerous indeed. I wear a cap and try to stay out of the sun most of the time. I've had 2nd degree burns with huge blisters caused by sunburn myself when I was young, so I always try to stay out of the sun when possible.

And during a long walk in the heat, hydration is very important. So we're looking for places where we can refill our bottles before we go. In The Netherlands we have quite a few public water taps, so you sometimes find those along the route.
I have an app which shows them on a map.
