Three days is enough to see the best of Los Cabos if you cluster activities by area and let the water set the pace. This plan starts in Cabo San Lucas, moves along the Corridor and finishes in San José del Cabo. It assumes you have a car or use hotel transfers, and it keeps each day to one big outing and one easy one.
Day one: Land's End and the marina
Start early with a boat to El Arco while the sea is calm. Glass-bottom boats leave the marina all morning, and the quick loop passes the sea lion rocks and the Arch, with an optional landing at Lover's Beach. If you prefer to paddle, a glass-bottom kayak trip reaches the same spot on your own power. Follow it with lunch at the marina, then a long afternoon at Medano Beach, the town's one broadly swimmable beach, where beach clubs rent loungers and water taxis wait on the sand. Finish with a sunset catamaran or a stroll along the marina walk, and dinner at a table with a view.
Day two: snorkeling and the Corridor
Spend the morning on a snorkel cruise that links the Arch with the calm coves of Santa Maria and Chileno, or drive to those beaches yourself and snorkel from shore. Both are public, both are shallow and clear on a good day, and both are much quieter before the tour boats arrive. Eat a late lunch at a beach club or continue east. In winter, swap the snorkel boat for a morning whale watching trip and keep the afternoon free. Golfers can fit a round on the Corridor into the same day, and spa lovers can book a treatment late in the afternoon.
Day three: San José del Cabo
Drive east to the colonial heart of the cape. Start with a walk around the plaza and the mission church, then explore the Art District's galleries, many of which open late in the morning. Have a long lunch in a courtyard restaurant. If you like nature, fit in a morning at the San José estuary first for birds and a free walk beside the beach. If you like food, take a taco tour or a cooking class. On Thursday evenings in the high season, the Art Walk turns the streets into a free festival, and it is the best way to end a trip.
If you have a fourth day
Choose between a Todos Santos day trip on the Pacific coast for galleries and orchards, a full-day Cabo Pulmo reef trip, or an adventure day with ATVs, camels and a zipline. Each is a full day with transfers, so book ahead.
Logistics that help
Book boat trips for the morning, when seas are calmer and light is better. Reserve sunset sails and popular restaurants in the high season. A car helps on the Corridor, but taxis and hotel cars cover most trips, and parking in the marina area can be tight. Carry sunscreen, a hat, water and cash for tips, and use reef-safe sunscreen. Respect swim flags, since Pacific-facing beaches can be deadly.
Adjusting the plan
Travelers with children can swap the late-night sail for a morning glass-bottom boat and an afternoon at Chileno Bay. Couples may prefer a sunset cruise on day one and a Thursday gallery night. Active travelers can trade the beach afternoon for a desert ATV or horseback ride. Whichever mix you choose, keep the evening of your arrival and the morning of your departure light, since airport transfers can be long and traffic on the Corridor is unpredictable.
Alternatives by interest
Foodies can replace the beach afternoon on day one with a taco tour in San José and a cooking class, and keep the sunset sail for the final night. Wildlife lovers can book a morning whale watching boat in winter, then add an estuary walk on day three. Golfers can fit a round on the Corridor on day two and spend day one on the water. Travelers who dislike early starts can reverse the plan so that San José's galleries come first and the Arch cruise falls on the second day. Keep a little buffer between activities. Always confirm tour pickup times the evening before.
