If you want 700c wheels, which I was told roll easier especially up hills, check out the Trek 7100 WSD, under $500, upright hybrid. 700x35 tires which should be OK for smooth unpaved paths. I just bought one but have only used it on pavement so far, except for riding a little over the lawn. The Navigator has 26" wheels and a little bit different geometry. The Giant Sedona also has 26" wheels, the Cypress has 700c. I believe these all come in XS. Check out the Trek and Giant websites for details. Good luck with your decision.
