Spring is here, and for those wanting to stretch their legs outside, several day-hikes and overnight backpacking adventures are available just north of the City. All of these hikes are accessible by train, in some cases in conjunction with a cab ride.
These particular hikes are not for those desiring a mildly-exerting walk in the woods. They offer dramatic mountain views and, as such, are strenuous, though doable for most fit people. As with any hike, these routes require basic navigational competence based on an actual map, not Google. (While Google Maps may work in a pinch, you can’t depend on service.)
