We just got back from Cabo San Lucas, and dove Cabo Pulmo one day. We did three days of diving with Manta Scuba out of CSL, and they took us (2 divers) and two other couples up there. We went in a van, and I have to tell you, the last five or six miles was brutal. The pavement just stops, and then you are on what is basically a widened cart path.
Boat launching system was a site to see, the ingenuity is amazing.
We were rewarded with two extraordinary dives. The first one, on a wreck, was hosted by about six or eight Bull Sharks, who were not bashful at all. The second dive was out in the middle of nowhere, but we got to witness a ball of hundreds of Jacks, which just swirled above us in an endless stream of fish.
Packaged together with our other two dive days, I think the cost of the Pulmo dive was about $250 (more or less) per diver, which included lunch.
Plan to post a full report with pictures as soon as we download our camera.
