Walking is fantastic exercise - I used to walk about two hours a day and it helped keep me focused on eating healthily as well as providing a form of exercise that I really enjoyed. However, since moving to an area where it is quite hilly and isolated, I do not walk at all in the same way.
I struggled to find an alternative, too, but I would recommend trying a Lesley Sansome DVD. I do her 2 mile 'Walk away the pounds' DVD practically every day. It only takes half an hour and is more than just a walk, even if a lot of it revolves around walking on the spot. Even vigorous housework or a spot of gardening (if you have one) can help to make you feel you are being more active and you might be able to build on that.
As beautiful as a walk around the lake sounds (wow!), it seems you are beating yourself up about not doing it every morning. Be kind to yourself, you can find other ways of getting to your goal.
