"I've been hiking in this park many times mostly because it is so near to me, but it also has really nice views. You can definitely spend a day there if you go around the whole thing. As far as newts--sorry, never saw any--maybe the fact that people let their dogs swim in the "protected" bogs? There is one bog that has chorus frogs. They sound like bullfrogs an all sing at once. If you step close to the pond, they all jump into the water. You have great views of Mt. Diablo from here. "
