Parked and entered at Boca Catalina (easy parking right at beach... Look for big yellow house). Easy entry through small sandy beach which lets you avoid rocky entry. Drifted north along rock wall past Catalina Cove, Arushi, and Malmok, then had to swim back against current (not too bad) to get back to sandy entryway at Boca Catalina. Overall, fairly easy. Coral formations ok, lots of schools of fish, but not great varieties. Snorkel blats stopped offshore at about 10am, but only stayed for 20 minutes or so. We could see dive boats further offshore for the wreck, but it seemed too far to try to snorkel out there.
