The first part of the trail is super-easy unless you decide to climb on some of the gorgeous bluffs and rock formations along the trail, an act explicitly and strictly forbidden by the signs. Therefore, we did not touch the bluff with the cave, where the signs were, but we did ascend a very small offshoot in front of one of the formations to find the perfect spot for an ambush, should one ever seek to become a bandit. The last formation before the washed-out bridge was covered with a gaggle of ten children, so we slid past that one as quickly as possible.
If you're looking to avoid hills, however, you should definitely turn back at the site of the ex-bridge or face immediate disappointment. The ascent begins immediately after; while not overwhelming, it was certainly strenuous enough to make this old woman pant a bit.
I can't comment much on the rest of the scenery at this time, because it was late dusk while we finished the trail and the light was dim. What we could see was interesting enough for us to mark this hike for a return trip so that we could get some decent pictures.
All in all, a very nice hike, and more enjoyable than I would usually expect from a paved trail.
Decent exercise getting up to the ridge, a lot of elevation but not too steep due to the switchbacks in the trail. Some nice scenery, but no specific points of interest worth mentioning. The only real drawback to the trail is that it's never out of earshot from the main road, so the traffic noise is constant.
