- Whales: Dec–Apr, from the Cabo San Lucas marina. Peak is Jan–Mar.
- The Arch (El Arco): sea lions year-round, an easy short bay trip.
- Cabo Pulmo (a marine park, ~1.5 h east) — the best snorkeling and diving in the region.
- Be responsible: keep your distance, never touch, and pick licensed operators.
