This steep, heart-pumping hike is sure to have a fantastic panoramic view.
The Monserate Mountain Trail loop starts out with a steep, heart-pumping, 1200 foot climb. Along the way, you'll find trail markers that represent every 10 stories of the original World Trade Center, placed there for the Fallbrook Firefighters 9/11 Memorial Hill Climb. This area is home to a wide variety of plant and animal species, including the endangered California gnatcatcher. At the top, enjoy panoramic views of the Peninsular Range to the east and the Pacific Ocean to the west. Head straight back down or hike a loop that rewards you with more great views into the Agua Tibia Mountains. This is a difficult 4-mile hike with an elevation change of 1500 feet. The hike is scheduled from 9 AM–1 PM.
