On Google Earth it looks like there is a road that runs up over the hill to the southeast of Z. It appears to end up on the ridge with a bit of a "goat trail" winding back down to the beach (playa larga?). Measuring it seems to be about 5K off of paseo de la Bahia in front of hotel JB. Any thoughts or experience with it? I know some might question leaving the beaten path in Mexico these days, but then sometimes our tourist paranoia can be an over-reaction. If its safe and passable, it may be our kind of hike.
