There are so many places on the Monterey Peninsula to bike and hike but if you don't want to even leave the Laguna Seca Recreation Area, there's plenty of places to do both right here. Besides the roads and trails readily available on the grounds, there is Bureau of Land Management (BLM) space right next to the campgrounds.
