The only National Park in San Diego!Cabrillo National Monument is a great place for short hikes, tidepools, whale watching and one of the best views of the San Diego Downtown Skyline.I would highly recommend the short Bayside Trail which takes you down to the water. Once you hike back up, stop off at the Light House and climb to the top.The views of the Pacific are amazing and well worth it to watch a beautiful sunset. If you are staying for a sunset, make sure to bring a jacket and/or blanket because it can get chilly.
