5b is the best overall overlook (several actually) and is very accessible (a short 1.5 mile round trip hike via 6 from the parking area).
4b offers a few scenic overlooks with unending views toward the horizon.
Not that impressed with 4a.
Trails 3, 4, and 5 are fairly rocky. A lot of sun with some intermittent shade. 2a is much shadier and wooded, although the creek was dry during our hike.
