Can any one give me details on how to park/access second beach?
While it does not answer your question specifically, the National Parks Service does have this information on warnings and dangers for those who are going to this area:
A PDF of the park map is here:
First Beach, Second Beach and Third Beach are shown on the map just south of La Push.
Goodfish has pretty good descriptions of these beaches on her set of pages. Her second beach tip is here:
