Went there for the first time today. It's in Imperial Beach - South of San Diego almost on the US/Mexico border. There are quite a few nice trails to walk and a good variety of birds. Highlights of today were a breeding pair of Northern Harrier's constantly hovering around the scrub, and a glimpse of a (endangered) light-footed clapper rail (Jindi spotted it in some moving grass.) There was also a rabbit about the size of a horse (exaggerating a LITTLE.)
Here are some photos of the view:
