Walking is a great way to lift your spirits, explore the real world, see places you wouldn't ordinarily see & discover the real world!  If you want to walk, why not walk with animals?  Walking alongside a new animal friend can help awaken our interest in the world, as we watch to see what interests them, what they sniff at, see in the bushes that we don't & it can be a great way to meet other people & make new friends.  
You can walk with llamas for a great day out, walk with wolves, stroll around nature reserves or help dogs by walking them
