Beneath the Arch: Snorkeling Cabo’s Living Aquarium
A calm cove, big ocean energy, and tacos to seal the deal—Cabo’s classic day on the water.
Morning slides across the marina in a slow golden spill, and Cabo San Lucas stirs to life. Pelicans patrol the docks like old-timers with opinions, while sea lions bark at skiffs easing into the channel. Your boat noses out past Medano Beach, where the shoreline hums, and aims for the granite gate ahead. El Arco—the famous arch at Land’s End—stands where two vast personalities meet: the Pacific rolls in with swagger, the Sea of Cortez pushes back with silky insistence. The current has its say today, fingers of blue tugging the hull, daring you into the day’s swim.
Trail Wisdom
Go early for glassy water
Morning departures usually mean lighter winds, fewer boats, and better visibility at Chileno Bay.
Wear a rash guard
A long-sleeve UPF top protects from sun and reduces the need for sunscreen that can harm reefs.
Fin technique matters
Keep your kick small and controlled to conserve energy and avoid stirring up sand over the reef.
Seasick? Prep in advance
If you’re motion-sensitive, take medication 30–60 minutes before departure and focus on the horizon when underway.

Conservation Note
Use reef-safe sunscreen and avoid touching coral or rocks; fins can damage fragile organisms with a single kick. Follow guide instructions to minimize impact.
El Arco’s granite is part of the Los Cabos batholith, shaped by millions of years of erosion at the meeting point of the Pacific and the Sea of Cortez.

Common Questions
Do I need to be an experienced swimmer to snorkel?
Basic swimming ability is recommended. Life jackets and flotation aids are typically available, and you can always stay close to the boat in the protected bay.
What’s the water temperature like?
Water ranges from the mid-70s to mid-80s °F in summer and early fall, and mid-60s to low-70s °F in winter. A rash guard is sufficient for most guests.
Can we get off the boat at the Arch?
Landings at the Arch are not permitted and conditions are often unsafe; you’ll view it from the boat and then snorkel in a calmer, protected bay.
Are food and drinks included?
Yes—expect a casual meal (often tacos and salad) and an open bar for post-snorkel refreshments. Options may vary by departure.
Will I see whales or dolphins?
Dolphins are possible year-round; humpback whales are common offshore in winter. Snorkeling focuses on reef fish, rays, and occasional turtles.
Is the tour suitable for kids?
Yes. Calm-water snorkeling at Chileno Bay is family-friendly. Check age policies and bring a snug-fit kids’ mask if your child has a favorite.
What to Pack
UPF rash guard for sun-safe hours in the water; compact dry bag to protect phone and wallet on splashy rides; polarized sunglasses to cut glare while spotting wildlife; motion-sickness tablets if you’re sensitive to chop, taken before departure.
Did You Know
Jacques Cousteau called the Sea of Cortez ‘the world’s aquarium.’ During extreme low tides, a small beach can briefly appear beneath El Arco at Land’s End.
Quick Travel Tips
Book a morning tour for calmer seas; bring cash for tips at the marina; confirm your pickup or meeting point the day prior; plan extra time after the tour—traffic between Cabo San Lucas and SJD airport can be heavy.
Local Flavor
After docking, walk to Medano Beach for a cold lager at Baja Brewing Co. and sunset views over Land’s End. For a casual feast, Tacos Guss serves standout al pastor and grilled shrimp. If you’re staying in San José del Cabo, swing by the Thursday Art Walk for local galleries and street eats.
Logistics Snapshot
Closest airport: Los Cabos International (SJD). Marina departure: Cabo San Lucas Marina, ~40–45 minutes by car from SJD. Cell service: Good in town and near shore; spotty offshore. Permits: No personal permits needed—follow marine protected area rules and crew instructions.
Sustainability Note
This coastline borders sensitive reef zones—use reef-safe sunscreen, keep fins up over coral, and pack out all plastics. Wildlife is protected; view sea lions and rays from a respectful distance.
