Soquel is wonderful .. very family oriented, very safe and friendly and close to everything.
However, it's not one of the mountain towns that i assume you are thinking about and finding an inexpensive rental is not easy.
But there are some really lovely and rural areas in Soquel and you can find privacy and quiet but without feeling really isolated and "out in the boonies".
And there are many "neighborhoody" areas (more sub-urban) as well. (same with Aptos)
If i may be so bold, what is your monthly allotment for a rental?
Just so you can get an idea of rental prices in the county of Santa Cruz, here's a link to Craigslist.

Don't forget to click on the little box that says "cats" and if you see any rentals that are way below average, it's spam and will be flagged for removal at some point.
Soquel and Aptos are my two favorite towns in the county.
Aptos is also expensive and like Soquel, there are many places to live where you can be immersed in nature, have peace and quiet but not feel like you're far away from everything.
S.C. proper and Capitola are more sub-urban although there are locations in S.C. proper that are very rural and still very close to shopping, activities, etc.
And again, expensive.
Santa Cruz County, California - Wikipedia, the free encyclopedia
When you consider living in the mountain towns near Santa Cruz (some are in the actual county of S.C. [like Scotts Valley and Bonnie Doon] and some not [like Felton, Brookdale, Boulder Creek]) remember that, while the thought of living in the redwoods may seem romantic, after a winter of cold and damp and no sun, you may never want to see a redwood tree again.
Living in them is wonderful in the summer but in the winter .... very challenging for some.
It just depends on how much sun will fall on the property during winter months.
Also, many parts of those areas in the mountains i mentioned are not as cheap as one would think.
This is a very "hot" area and finding housing can be very challenging.
And though, in general, i wouldn't recommend Watsonville, there are parts of it (closer to Aptos) that are actually very nice.
Being spiritual but not religious will not be a problem in this county.
It's liberal, open, friendly, diverse and tolerant.
The bus system is excellent and it's a very bike friendly community.
If i were a parent, i'd be glad to raise my kids here.
The nature is very strong here, you can live rurally, and yet there is sufficient culture, activity, etc. so that you can kinda have the best of both worlds.
It's a beautiful place to be ... just pricey!
Hope that helps.
