Snorkeling is a relaxed way to observe underwater life from the surface with minimal gear: a mask, snorkel, and fins. You float near the top, breathe air through the snorkel, and enjoy clear views of reefs, fish, and shorelines without heavy training or tanks. In contrast, scuba diving lets you descend below the surface with a tank and regulator, giving you the freedom to explore deeper, stay longer, and approach more marine life, but it requires formal training, more equipment, and stricter safety procedures. If you’re after easy access to vibrant underwater scenery and light gear, snorkeling is ideal; if you want to venture deeper and farther from the surface, scuba diving offers greater immersion and discovery.
