Southwesternmost point en los contiguous Estados Unidos. During WWII there was an auxillary airfield at this site. Later on the land was used as a naval bombing range. Areas of the park today contain unexploded ordnance... so watch your step. And enjoy your view to the south - a big black border fence between us and them. If the fence wasn't there, one could very easily take a leisurely stroll along Tijuana's beachside community, perhaps grab some lunch or a Coke. Sadly, that just isn't allowed.
