Net Zero Expeditions operates responsible, small-group marine wildlife outings based from the San Diego coast. Specializing in whale watching, dolphin encounters, cageless shark snorkeling, and pelagic wildlife trips, the company runs Zodiac RIBs for intimate viewing and the speedy Aretai for open‑ocean expeditions. Trips are intentionally limited to very small groups — select voyages seat just six guests — to reduce disturbance to animals and provide closer, safer observation. Professional naturalists guide every excursion, offering species identification, conservation context, and on‑water education. Popular itineraries include a Blue Whale Expedition, a three‑hour Signature Whale & Dolphin Watching Tour, a six‑hour Blue & Mako Shark Snorkeling experience, and a six‑hour Pelagic Wildlife Expedition focused on open‑ocean species like the Mola mola and bait ball events. Net Zero Expeditions emphasizes eco‑conscious practices, cageless, noninvasive snorkeling protocols, and adherence to local wildlife guidelines. The company provides all necessary gear for snorkeling trips, maintains modern safety standards aboard the Aretai and Zodiac RIB, and prioritizes low‑impact interactions that benefit both guests and marine life.
