August 14, 2022,Los Peñasquitos Waterfall Loop from Mira Mesa

The navigation will ask you at the waterfall to carry the bike across from the north trail I to south trail, it's a bad idea and too painful, skip that part and take one of bridges to cross over to south trail, other than that it's a great trail and will challenge you on everything
