Miles of excellent mountain biking trails and forest roads. Deep redwood forest, with a few old growth remnant trees here and there. While the city does some logging, it is sustainable and very selective. Lots of trilliums in April. Look for the red Clintonia on the ridgetop roads in late spring. There are some homeless folks who illegally camp, but over the 18 years I've used the forest I don't see them as a major problem. I have seen both bears and mountain lions -- very wild country, yet very popular.
