San Pedro Valley is San Mateo County park located in Pacifica, California. This park consists of beautiful hiking trails, lush valleys, waterfalls, and mount lions that suit perfect for anyone. It wasn’t difficult hike, the trails wasn’t too steep and the weather wasn’t too cold. You can see the beautiful view of pacific ocean at the top of the trail, forcing me to come back in the near future. The park contains variety of habitats including grassland, coastal shrubs, coast live oak trees, madrons, toyons, coffeeberry and many more.

We departed the parking lot around 1 pm and this time we didn’t have problem exiting the parking spot. The ride was relatively longer. It took about 40 minutes to get there but it didn’t feel like that long since we got to see beautiful pacific ocean next to the road. The weather was amazing, and I barely wear my jacket. Some trail was little muddy but overall it was clean and easy to hike. My favorite time in the trip was when we were up at the top. It was good to see some familiar plants we saw in the previous trip such as the giant madrone and toyon and coffeeberry. We could see the beautiful pacific ocean with villages and forests. We couldn’t see any mountain lions unfortunately, but next time.
