The trail to Monument Peak differs by season. Better travelled in the winter and spring months. Many raptors can be spotted, I counted 8 red tail hawks and one perigrin falcon. Other wildlife – wild turkeys (lots of em), deer, coyote, bob cats, squirrells, rattle snakes and mountain lions.

One of the surprises of this hike were the greenbelts we encounterd along the way. Unlike the Mission Peak hike where you are exposed most of the way, the trees in the greenbelt were a welcomed site. Mostly Oaks and California Laurel Bay trees. Spring time and early summer bring lots of wildflowers, unfortunately, it was cold and overcast on our trip and the wildflowers we saw were mostly closed up and hiding.

Kris – This area was pretty confusing. There were no trail markers to Monumnet Peak. In fact there was no way to know where Monument Peak is. The park map didn’t help since it showed the trail going right through the peak, but the topo maps show it at a different location. I went ahead and added the route to the peak, although I did not actually go up there since I was misled by the park map. To the peak – R at 4-way on Road then R up foot path. To continue on the loop – L at 4-way to Agua Caliente Trail. Going straight on the 4-way is a great trail to Mission Peak and a good alternate route for a much longer hike.

The route down is pretty steep but gives a great view of the bay area (on a clear day). The trail is a fire road, mostly gravel and dirt and can be pretty tough after a rain because of mud or after it is dried can be tough on the feet because of the cattle in the area really mess up the trail.
