If you want to try breathing underwater on holiday, ask for a supervised introductory scuba session. You can try it without a certification. If you mainly want to see fish from the surface, choose snorkeling. If your goal is to earn a dive certification, ask about a course and how many days it needs.
The regular Catalina Island tour is a snorkeling and beach trip. An introductory dive requires separate confirmation for your date. Ask whether you and any snorkelers can share the same transport and boat. The Catalina Island guide explains how the island day works. If diving is the reason you’re going, a dedicated session with a dive center in Bayahibe lets you plan around the instructor’s schedule. Confirm the meeting point and return ride using our Bayahibe and Dominicus guide.
Your dive professional explains the equipment, hand signals and plan. You start with practice in a pool or water with similar conditions, getting used to the regulator and learning basic skills under supervision. Tell the instructor if you’re nervous and agree on how to signal that you want to pause. Ask whether an open-water dive is planned and what happens if conditions or readiness make it unsuitable that day.
Send your date, accommodation, ages and preferred instruction language. Ask about swimming requirements, group size, who supervises you, equipment, total price and cancellation terms. Request the medical form in advance and ask the dive center whether you need clearance. Share the time of your next flight so they can check the schedule with you.
