Scotts, tell me about beautiful places please!

NYCNika

After much wavering, I finally narrowed down my choices and decided to spend remaining days of my fall European vacation in Scotland. Now I am faced with hundreds of towns and lakes very little time and it is overwhelming. I thought that perhaps some locals here can offer valuable advice.

Primary purpose of this trip will be scouting out a place to rent a house in July of next year. I want it to be a dream vacation with our toddler son. I will save for it, save our vacation time, and I'm looking forward to it very much.

If there are some locals here, could you advice what place can satisfy all of these criteria:

1). Stunning scenery and fresh air, lots of outdoorsy stuff to do. Low crime, of course.
2). Access to good fresh produce and preferably organic dairy, meat and wild fish.
3). A town or a village with some restaurants/bakeries with good food.
4). Possibility of renting a nicer home, with large outdoor space.
5). Friendly locals and nice lively atmosphere.

Would you recommend coastline or the highlands? What should I know that most visitors don't?

I liked this home http://www.ardfenaiglodgemull.com/ (don't know much about location) but than I saw "children over 8 are welcome) What am I supposed to do with a 3 year old? This vacation is so that we can all spend time together as a family.
House looks nice, I would love to rent something like that.

So this fall we (just DH and I) will go and will only spend 4-6 days. I'd like to do something outdoorsy (like to see gorgeous scenery on horseback, perhaps multi-day horse or hike trip) take stunning photos of the most beautiful scenery and decide on a place to rent next year.

This years short trip is beginning of October. Next year I want to leave NYC for the entire month July (dust, bad smells, blazing sun and 90 degrees).

Thank you so much for any help you can give me!
