Occasionally I take Otis, the household dog, out for walks in the woods around our house. It gives me an excuse to go get some exercise, and it gives him a chance to run off some of his excess energy. There's a lot of stuff going on in the woods if you care to stop and take notice, so it's never boring. There's always something new to see around the next tree or over the next hill. Otis loves it even more than me, because there's so much to see and smell, and there's room to run so he usually races around at top speed, while I plod or occasionally jog along behind him.
There's a road (of sorts... much of it unmaintained) around and through the woods we walk in. Going through the woods usually means going through the trees and the brush.
There is a snowmobile trail through part of it tho, and that makes walking a bit easier (especially in the winter), if we choose to go that way.
Off the path, there's a nice tree which has fallen, and makes a good seat upon which to sit (tho maybe not in the winter). Nice place to make a phone call from, if you have a cell phone. 
It's an old-growth forest, and during the summer the forest floor is covered with dead leaves and surprisingly springy moss. There's a decent amount of space to walk between the trees, even if you're a tall human like me. Otis goes bolting through the undergrowth at speeds I can't match, through holes I have trouble getting through.
Here's Otis looking down from atop a hill. He's much more a go-getter type, whereas I'm much more contemplative while I'm in the woods.
