I have had very good luck with alltrails.com to find local trails to run.
You can load it on your phone/ PC/ tablet/ whatever. You can pay if you want to download stuff but the free version will give you the information you need.
Under "What to do", select "offroad driving" and then you can also select difficulty (Easy/ Medium probably good for 2wd) and read the write ups which can usually tell you if you can make it using 2wd/ need high clearance, etc. Then, just move/ zoom the map in and out for the area size you want to search and it will search just that area.
Sorry, didn't mean for this to come off like a product plug, just a handy tool I use a lot.
