The Los Peñasquitos Waterfall – Los Peñasquitos Falls loop from Mira Mesa offers a refreshing escape into a surprisingly wild canyon within San Diego. This moderate 4.8-mile (7.7 km) hike, with its 347 feet (106 metres) of elevation gain, guides you through lush oak and sycamore groves, past a meandering creek, and to a charming waterfall cascading over volcanic rock. The terrain shifts from wide, gravelly fire roads to narrower dirt paths, providing a varied and engaging experience for hikers.
Plan for about 2 hours and 5 minutes on the trail, starting from the Camino Ruiz Community Park, which offers convenient parking.
