When I lived in southern Cal I used to go down through Mexicali and down to San Felipe.
I lived in Tucson and Phoenix for about 20 years total and usually went down along the Sonora Side. Puerto Penasco in the north, and then several remote fishing villages of Desemboque, Puerto Lobos, Puerto Libertad and on Down to San Carlos. Puerto Penasco was okay, but got to be overrun with snowbirds and the college party crowd. Also, the water was not always as clear up near the top of the long tidal washed neck.
My favorite spot was Puerto Lobos. Very remote, no water, no power but a few fishing shacks and a lighthouse. You could launch a small boat, but there was plenty of good fishing from the rocks or out in a tube. Easy to catch over 200 fish in a morningâŠwith at least 30 to 40 species in the mix. Crystal clear water, warm as bath water. Great for diving and harvesting some lobsters, scallops and other seafood too.
Here is a link to a thread I put up on the float tubing board quite a while back.
