We hiked the Ida trail to the summit & took the Sunset trail back down to the Perimeter road since we were camping. The Ida trail is steep & shorter, while the Sunset trail has long switchbacks & not steep. We preferred the Ida trail which also had better views, but the Sunset trail has more shade. We saw many deer on the hike up. We hiked on a very clear day so you could see 4 bridges & a 360 view of the Bay area cities. There are lots of shrubs at the top so to get the best views you need to stand on the picnic tables. Be sure to bring a good camera, water & food, & binoculars.
