What should I avoid in Cancun?

The first trap sits between customs and the exit doors at Cancún International (CUN): the men in polo shirts at desks marked 'Information' or 'Transportation' are mostly timeshare sales staff. The 'free' ride or cheap Xcaret ticket they offer usually comes with a 90-minute sales pitch the next morning, so keep walking until you reach the curb outside Terminal 3, and know that Terminal 4 runs the same gauntlet. Outside, the air hits like a damp towel. The ADO bus counter is right there, and a ticket to the downtown terminal on Avenida Tulum costs around 130 pesos. A walk-up taxi to the Hotel Zone can run USD 60 to 90, so book a shuttle in advance if you're travelling with kids or heavy bags. Buy an eSIM before you fly, because the CUN Wi-Fi tends to drop and you'll want maps working at the curb.

Money is the second leak. The official rate on 15 October 2026 stood at 18.52 pesos to the dollar, and shops and restaurants along Kukulcán Boulevard often take dollars at 15 or 16, a quiet 15 to 20 percent markup. Pay in pesos, and when a card terminal asks whether to charge in USD or MXN, pick MXN. Use ATMs inside BBVA or Banorte branches rather than the standalone machines around La Isla and Plaza Forum, which have a reputation for skimmers. At Pemex stations, watch the pump reset to zero and say the amount out loud as you hand over a 500-peso note, because swapping it for a 50 is an old trick here. Hotel Zone taxis have no meters, so agree the fare before the door shuts. The R-1 and R-2 buses run the length of the strip for about 15 pesos, rattling along with reggaeton blasting, every few minutes.

The sea deserves more respect than the brochures give it. The east-facing beaches from Punta Cancún south to Playa Delfines face the open Caribbean, and both Playa Chac Mool and Playa Delfines carry a long record of drownings in the undertow, so when the red or black flag is up, stay on the sand. For water as warm as a bath and far calmer, head to Playa Langosta or Playa Tortugas on the Bahía de Mujeres side. Sargassum is the other variable: from roughly May to September, the brown seaweed can pile up knee-deep on the eastern beaches and smells of rotten eggs as it rots in the heat, so check the Quintana Roo sargassum traffic-light map before you book a beachfront room. Hurricane season runs from June to November, and mid-October is still in its peak. On 15 October it was 27°C, felt like 32°C, with 86% humidity and light showers, so book refundable rates.

The packaged Chichén Itzá day trip is worth skipping: it picks you up at 7am, stops at a cenote and a buffet, and deposits you at the ruins at midday alongside dozens of other coaches. Rent a car and be there when it opens at 8am instead, or consider Ek Balam, where the crowds are thinner. Coco Bongo is a similar calculation; unless a USD 100-plus open-bar ticket is the whole point, the Party Center strip at Kukulcán km 9 is loud, sticky-floored, and expensive. The dolphin swims sold along Kukulcán Boulevard are a pass too. For Isla Mujeres, take the Ultramar ferry from Puerto Juárez, north of downtown, because the Hotel Zone piers charge more for the same crossing. The quieter wins are the Mayan Museum of Cancún and the El Rey ruins a short ride south, where iguanas bask on warm limestone. Cancún scores 6.2/10 for solo safety (see the TTDI Solo-Safety Index), and solo travellers should use registered taxis downtown after dark.
