One of the top easy hikes in the Santa Cruz Mountains, and perfect for just about anyone, no matter their size or ability. And it's got a lake, which always adds to the pleasure of a hike. The trail tread up to the dam is easily wheelchair accessible, and beyond that is a little more difficult, including a hillside traverse - not recommended for strollers or wheelchairs - but there are escape hatches before then.
This can be made more adventurous by connecting to the open space preserves to the north (Russian Ridge Open Space Preserve) and south (Long Ridge Open Space Preserve); there's even an old Christmas tree farm to the south!
The lake generally has lots of waterfowl which are fun to watch.
