2wd for sure!
I got a PM about my route as well, so I will outline it here.
In my particular situation, we had campsites reserved at Hanna Flat campground.
FYI. I didn't keep track of any millages on this experience. I just kind of drove. So, I can't help with turn left after 3.58072 miles. However, I can operate google maps, barely, and will mark major intersections with GPS coordinates. Just C/P those bad boys into CLASSIC google maps and you're set
Day 1We chose to drive up from the OC via Highway 18. The entry point we used to 3n16 was Crab Flats via Green Valley Lake Rd.
Turn off from highway 18 at Green Valley Lake Rd.
34.219414,-117.071644
Green Valley Lake Rd is paved. The entrance to 3n16 is Crab Flats Rd. which is dirt. If you hit the lake, well you've gone too far. ( we hit the lake and turned around)
34.233448,-117.089466
Once on Crab Flats Rd. (3n16) you just kind of drive. Our goal for the day was to hit Coxey Rd (3n14) and hang a right.
Intersection of 3n16 and 3n14
34.319692,-117.01033
We then traveled from the intersection of 3n16 and 3n14 to Hanna Flat campground.
34.288859,-116.974312
Day 2We headed up to the intersection of 3n16 and 3n14 to do the second half of 3n16.
We traveled down 3n16 until we reached a sign that read something like 3 miles to highway 38 - 3n12 to Little Bear Summit and Hanna Flat.
34.309594,-116.927332
Since we were camped at Hanna Flat, it only made sense to loop it around. It worked. We were back at Hanna Flat
Day 3 A friend of ours in her FJ wanted to do some off roading so we did day 2 in reverse. Started at Hanna Flat and ended at the intersection of 3n16 and 3n14. At this point, we sent the FJ back to camp and we headed down 3n14 the other way towards Lucern Valley and Apple Valley.
Hopefully this all makes sense.
One tool we did use was having the Forest service maps on a tablet. Note. The file is like 20mbs. Give it a second to render and you can make sense of it.
