Miles of well-maintained trails for hiking and running with some gorgeous views. Come early, it can get really hot during summer time.

Hike to the top of the PGE trail to get an awesome view of the valley and the bay. Takes about 2-3 hours start to finish. Enjoy the wildlife you'll see on your way.
Fly some planes
One of my most favorite places!!! Great if you're looking for a nice walk with friends or, if you want to challenge yourself, pick a trail and get going! My favorite trail, Upper Wild Cat Trail.
Hiking is good for you. The wildlife is awesome and the air is clean. Be sure to bring large water bottles -- you can refill easily however you want to have some with you....
