Look deep into nature to connect to the rhythm of the universe. Offline is the new luxury and a necessity to all of our health and wellbeing. We started the Los Penasquitos Lagoon hike at the end of Flintkote Avenue in Sorrento Valley, California where the trail begins on the west end of the marsh. As the trail winds around the edge of the lagoon on the backside of the towering cliffs of the Torrey Pines Reserve the trail becomes less traveled and more overgrown. I'd recommend wearing pants and shoes.
