The Forest of Nisene Marks State Park is one of the best hiking venues in the Bay Area, although technically it is outside the Bay Area, in the coastal areas south of Santa Cruz. We managed to confuse ourselves by taking a wrong turn on the Doughnut Trail resulting in a very steep descend followed by very steep ascent along some un-named cycling trails. To "compensate" our hiking group, we decided to go through the closed Aptos Creek trail, using the ropes installed there to climb back out of the canyon in the area where the single plank bridge used to be before the 2016/7 winter storms when in fell into the ravine. Great hike and challenging experience.
