I've been trying to find long, purposeless walks, but invariably I always end up walking a circuit, so the purpose becomes "finish the circle and get back to work". And I feel that takes something away from using a walk to get away from stress, instead it becomes one more task I have yet to finish.

There's an arboretum here in town but it's a drive to get there. I wish I lived next door to a forest.

Any coffee shops or bars that sell coffee on the way? Or perhaps a bus route where you walk to the bus stop and get the bus back?

There's an idea. I'll look into that, thanks.

If going on a nature walk with a coffee in hand, people need to be prepared to hold on to the empty cup until they get to a garbage can.
