proudindiv is right...and not right...Wreck Beach is actually a string of beaches that stretches from the breakwater (proudinva's kml) and wraps all around the UBC endowment lands to Arcadia Beach. The entire stretch is clothing optional. You can see, if you zoom in on proudindiv's kml the section of Wreck Beach, that this is the "main" Wreck Beach known by most and accessed by the 400-some-odd stairs of trail 6.
