Playa Delfines and the CANCÚN letters without the queue

The letters at El Mirador

The lookout is called El Mirador. The queue for the letters is longest from mid-morning through the afternoon. The beach faces east, so in the first hour or two of daylight the light is soft and there is barely a wait.

The R-1 and R-2 Hotel Zone buses stop in front of the lookout. If you drive, the car park fills at weekends, and by mid-morning in high season.

The sand and the flags

Below the lookout the sand is wide, white and open, with a line of free palapa shades along it. There are restrooms, showers, a playground and a ramp down onto firm sand. There is no restaurant, no bar and nowhere to rent a sunbed, so bring water with you.

Lifeguards work from 9 a.m. to 5 p.m. and fly green, yellow and red flags. This stretch faces the open Caribbean with no reef in front of it, so red flags are common and swimming is often closed. If you came to get in the sea, treat Delfines as a beach for looking and walking, and swim somewhere else.

El Rey across the boulevard

Zona Arqueológica El Rey is on the lagoon side of the boulevard, almost opposite the beach, so it folds easily into a beach morning. Expect low grey platforms, a stub pyramid, a stone causeway and a lot of big iguanas sunning themselves on the walls. It opens every day from 8 a.m. to 5 p.m. and costs 75 pesos. Allow 30 to 50 minutes. There is almost no shade on site, so go early. If you want standing Maya temples, this is not the site for that.

The Maya museum at km 16.5

A short bus ride north, the Museo Maya de Cancún is where to go when the flags are red or the sun is too much. The galleries hold ceramics and objects dug up across Quintana Roo, with films about the peninsula's caves and underground rivers. The same ticket gets you into the San Miguelito ruins behind the building, where a shaded path through low scrub leads to a small stone pyramid.

Entry is 210 pesos for foreign visitors and 105 pesos for Mexican visitors, who go free on Sundays. It opens Tuesday to Sunday from 9 a.m. to 5 p.m., with last entry at 4:30 p.m. An hour does both if you move quickly. Give it most of a morning if you read the labels.

Calm water in the north

The sheltered bay at the north end of the Hotel Zone is where the flat water is. Playa Langosta, at km 5, is about as calm as the Caribbean gets, roughly half a metre deep for the first 10 metres out. There is a lifeguard tower, restrooms and showers, a children's play area and wheelchair ramps, and you can hire umbrellas, loungers and kayaks. Natural shade is thin. The free car park is small and fills quickly, so get there before 10 or 11 a.m. in high season. Tour boats use the wooden pier in the morning and late afternoon, so swim beside it, not under it.

Closer to downtown, Playa Las Perlas is at km 2. It is the first public beach you reach coming from the city, with about 200 metres of sand on the same calm bay. It has been an inclusive beach since 2024, with amphibious chairs, loungers, matting laid across the sand to the water, handrails and accessible restrooms. All of that is free, but there is a limited number of each, so come early. There are palapas with little tables, a playground, restrooms and showers. There is no beachfront restaurant, and no alcohol is sold. Take the R-1 or R-2 bus from Avenida Tulum and ask for Las Perlas. The stop is about 200 metres from the sand.

A shrine on the sand

Playa Marlín at km 13 is the easiest beach here to reach without a car. The signed public path starts at the Plaza Kukulcán car park and drops straight onto broad white sand. There are showers, restrooms and a few palapas, lifeguards during set hours, and shops and lunch back up at the mall. The water is often rough, so read the flag. Parking is free but closes at 4:30 p.m.

From that same access, walk 400 to 500 metres along the sand toward Punta Cancún. That brings you to Yamil Lu'um, a small Maya shrine on a low bluff above the beach. There is no ticket and no need to book. Two squat columns split its doorway into three openings, and the Caribbean sits directly behind it. Allow 20 minutes for a look. Phone photos are fine, but tripods and drones need a permit. The final approach is sand and uneven stone steps, so it is not step-free, and the walk is unpleasant when the surf is up.

Isla Mujeres for a swim

If you want to swim properly, give a half day to Playa Norte on Isla Mujeres. It faces west into the bay and the sea floor shelves very gently, so on a normal day there is little or no swell. The sun sets over the water in front of you.

Ultramar boats leave Puerto Juárez in Cancún from 5:30 a.m. to 11 p.m., and the crossing takes 15 to 20 minutes. The fare is 290 pesos one way, or 580 pesos return. From the dock on the island it is about 0.9 km to the beach, roughly an 11-minute walk, or five minutes by taxi or rental golf cart. Midday is the busiest, so late afternoon into sunset is the better half of the day. Plan your way back: the last boat to the Hotel Zone piers goes at 7 p.m., while Puerto Juárez sailings run until midnight. Loungers at the beach clubs along the sand have a minimum spend of 200 to 500 pesos, and the stretches between the clubs stay public, so a towel costs nothing.

Before you go

Leave the museum and San Miguelito for a day other than Monday, and carry water, because nothing at Delfines sells it. Bus fares are cash only. See the Cancun guide and the Cancun hotel search.
