Los Cabos Yacht Routes — Arch, Santa María, Chileno and Beyond

The Cabo San Lucas Bay route, mile by mile

Most yacht days in Los Cabos start at Cabo San Lucas Marina, the dock complex at the foot of Médano Beach. From the marina mouth to El Arco at Land's End is barely 1.5 nautical miles — you are at the most photographed rock formation in Mexico within 15 minutes of leaving the slip. From there the route fans out east along the Sea of Cortez coast: Lover's Beach (the sand strip between two oceans), Pelican Rock (the wall dive site), then a longer leg of ~7 nm to Santa María Bay, and another 2 nm to Chileno Bay.

The whole loop, with three swim stops, is comfortably done in 6 hours on a 40+ ft yacht cruising at 12–15 knots. The Mexican Navy (SEMAR) publishes navigation notices and storm warnings for the Cabo San Lucas Capitanía de Puerto — captains check these every morning and route around closures. If a Northerly is blowing 25+ knots, the captain will skip Santa María (exposed) and run shorter loops inside the bay.

Route options by charter length

Prices above are base charter for a typical 40-ft yacht; fuel surcharge, port fees and Marine Park entry are usually invoiced separately. Larger vessels run 2–3× these figures.

El Arco and Land's End — the photo stop

El Arco de Cabo San Lucas is the natural granite arch where the Pacific Ocean meets the Sea of Cortez. From the water it is a 10-minute slow circle: captain noses the bow toward the arch, holds position with the engine, and gives guests 5–10 minutes for photos. Sea-lion colonies sit on the rocks east of the arch — you can hear them before you see them. Pelican Rock, just inside the bay, is a vertical wall dropping to ~120 m and one of the top wall-snorkel spots in Mexico.

Conditions at Land's End change with the swell. Pacific groundswell (Oct–Mar) wraps around the point and can make the arch zone bumpy; on flat days you can almost touch the rock from the swim platform. Captains rarely anchor here — they hover with the engine because the bottom is too deep and the buoys few. For guided snorkel stops the boat moves on to Pelican Rock or further east.

Santa María Bay and Chileno Bay — the snorkel anchorages

Santa María is a horseshoe-shaped cove ~7 nm east of the marina, protected by rocky headlands. The reef wraps around the inside edge — green water, parrotfish, the occasional puffer, and good visibility (15–25 m on calm days). It is a designated Refuge Area inside the Cabo San Lucas Marine Park; mooring buoys are mandatory and there is a Marine Park access fee (~$5 USD per guest) collected by CONANP.

Chileno Bay sits another 2 nm further east and is the calmer of the two — wider sand entry, gentler current, kid-friendly. It is the most popular family snorkel stop in Los Cabos because boats and shore swimmers share the same bay safely. On a busy day in March, you may share Chileno with 15–20 other yachts; captains who know the bay anchor at the eastern end to dodge the crowd.

For both bays, anchoring directly on coral is forbidden under IMO-aligned Mexican regulations and SEMAR enforcement is active. Reputable operators only use the designated mooring buoys or sand patches — ask the captain to point out the buoy line before you swim.

Fuel range, cruising speed and why the East Cape is a full day

Average Cabo charter yachts (35–60 ft) cruise economically at 12–15 knots. Pushing them to 22–25 knots burns roughly 2.5× the fuel per nautical mile. Most operators include a "reasonable" fuel allowance in the base rate and add a surcharge if the route requested exceeds it. The API BCS port authority publishes daily fuel prices at the marina pumps; expect $1.20–1.50 USD per litre of diesel.

Getting from Cabo San Lucas Marina to Cabo Pulmo on the East Cape is ~55 nm one way. That is 4+ hours of running time at economy speed, plus weather windows. It is technically possible to do as a 10-hour single day but you arrive with little snorkel time and head straight back. For a real Pulmo day you either depart at sunrise or book a 2-day liveaboard (see our overnight Cabo Pulmo itinerary for the full plan).

Sunset cruise vs day cruise — which to pick

The sunset cruise is a different product, not a shorter day cruise. It launches around 5 pm (later in summer, earlier in winter), runs the Arch loop with golden-hour light, opens the bar, and returns to the marina by full dark. Music tends to be higher tempo and snorkel gear is rarely deployed — guests stay dry, dressed, drink-in-hand. Pricing is typically 35–45% of an equivalent day charter.

Day cruise is the immersion product: swim suits all day, snorkel masks on the deck, lunch served at anchor, more downtime per stop. Most family bookings pick day cruise; most date-night and celebration bookings pick sunset. Combine: an early-day cruise that ends by 4 pm followed by a separate sunset cruise is a popular two-yacht day for big celebrations.

Wind, weather and anchorage rules

The dominant Cabo wind pattern in winter is the Norther — cold-air flow off the Sea of Cortez, 15–30 knots, mid-morning peaks. Pacific groundswell adds 1–2 m of background swell on the Arch side. Captains read both: a stiff Norther makes the East Cape rough but smooths the Pacific side; calm post-Norther days are the magic windows. Weather tools like WeatherFlow and NOAA offshore models are part of any serious captain's morning routine.

Inside the Marine Park, mooring buoys are colour-coded for vessel size and use class. Anchoring in sand is permitted only outside the reef buffer zone, marked on charts. SEMAR patrols are frequent in March–April peak season. A captain who ignores buoy rules risks a federal fine of 20,000+ MXN and a temporary licence suspension; ask before booking whether the operator carries current Capitanía paperwork and Marine Park user fees.
