Well the one trail coyote point (95% singletrack, strenuous climbs) is supposedly a type of trail where 'if you can ride this you can ride any trail', however the ranger informed me that it is not technically open yet.
The trails I usually ride are gravel trails (marked mtb trail/hiking trail), not as wide as fireroads. I usually do a there and back for 4 miles, then go on the road for a couple minutes to another gravel trailhead for another 4 mile there andback, and just rotate between the two. No harsh climbs, couple short steep ones, though if you are advanced they are probably easy to you.
We can try coyote point if you are up for an advanced ride, or we can just stick to the mellow trails. It's up to you. I have a map of all the trails too we can look at when we meet up.
I meet in the wrinkle cove day use area, at the end where the trailhead is.
