Another nice feature of Liberty Station: you can cross North Harbor Dr at Laning Rd and get onto the sidewalk that runs along Harbor Dr
this sidewalk takes you all the way to the Star of India (1.7 miles one way) and it is a nice walk / jog / skate / bike / etc – the sidewalk is well away from Harbor Dr for most of the distance and it goes through Spanish Landing Park which is right across from the marinas
