Yeah its very nice. The first half is kind of dusty double track. You get to a point where the trail splits and you have two options, continue on the double track or I think its called Limpia Chute, or something. Take Limpia Chute, both up and down. The double track section there is super loose, fist sized rocks, its no fun. Limpia Chute is mostly treed and some good views. The last bit to the summit is a scramble up head sized rocks, but not too bad. Its not too terribly hard of a hike, I think around 3 miles each way. My kids were 5, 7, and 9 and were fine.
They say you need a high clearance vehicle to reach the trailhead, and its probably a good idea, there's some creeks and rutted parts. The visitors center is nice with flush toilets and maybe showers, I don't remember exactly. I think they require you to camp close to the visitor's center in a field, but we stayed at the State Park and drove in for the day.
