Freiburg in Germany. The black forest literally starts at the edge of the city. It was a while since I was there, but we definitely walked from the city centre to the forest. Might have been 30 minutes. Would be quick on a bike. Zaragoza in Spain. Walked from the old city centre to the edge of the city (which was apartment blocks) in a reasonable time. It was mostly agricultural land, but I recall some forest along the river. San Sebastián, also in Spain. You can walk into the hills, but we went to the beach. Parks covered in homeless people is a US problem, in my experience. I've been around most of Europe and haven't seen anything like that. The homeless problem in the US is a policy choice, just like the urban development is. It's easily solvable given political will. Can you walk to a cafe?
