Score 87/100 · Order: Summit loop, 6 miles round trip · Free
Iron Mountain climbs about 1,100 feet over three miles of exposed chaparral to a summit with views across Poway and inland North County. It is the trail to graduate to after Cowles Mountain gets easy, and the surface is good enough for trail running.
Local tip: No shade past the first mile — start before 8 AM from May through October.
