Cozumel

Prioritise Palancar & Columbia reefs, San Gervasio Maya site, Punta Sur eco park & Celarain lighthouse, Museo de la Isla and El Cedral village. What you can skip without regret: the restaurants with photo menus and touts on the main square, any hop-on bus if the centre is walkable, and paid "panoramic" viewpoints when a free one gives the same picture. Cozumel is inland, so plan around heritage, food and landscape rather than beaches.

Stay inside or immediately beside the historic centre of Cozumel: you walk to the main sights, restaurants stay open late nearby, and you avoid paying for taxis twice a day. Pick the edge of the old town if you want quiet at night, and check the room faces a courtyard rather than a bar street.

Hire a scooter or jeep to loop the 60 km island road — there is no bus on the east coast. Taxis are fixed-rate by zone within San Miguel. As a rule: take the scheduled bus or train for the cheapest ride, an official taxi rank or a ride-hailing app when you land late or carry luggage, and never accept a lift from someone approaching you inside the terminal.

3 full days is the honest answer for Cozumel: one for the centre on foot, one for its museums and food, and one for a trip into Riviera Maya. Two days works if you only want the highlights; a fourth day is worth it if you want a slow morning and a longer excursion.

Budget $120–180 per person per day mid-range: $45–60 food, $20 transport, $35–60 excursions and cenote fees. Accommodation moves the total most: shoulder season in Cozumel can be half the July price for the same room. Payment runs on the Mexican peso (cards in hotels and restaurants, pesos for beach kitchens, taxis and cenote entry).

Day 1 — the historic core of Cozumel on foot, clockwise from the main square, with lunch where you end up rather than walking back. Day 2 — the single biggest sight first thing, then the market and the residential streets around it, and a viewpoint at sunset. Day 3 — one excursion into Riviera Maya booked in advance, back for a late dinner. Group everything by walking distance and never cross Cozumel twice in a day.

Anything with timed entry or a small group sells out first: the flagship monument or museum of Cozumel, guided tours with fewer than fifteen places, boat and wine experiences in summer, and dinner at well-reviewed restaurants on Friday and Saturday. Book those two to four weeks ahead in high season; everything else can wait until you arrive.

The classics are the same everywhere: unmetered taxis quoting a flat fare, "free" bracelets or flowers, distraction pickpocketing on crowded transport and at photo spots, card machines handed over pre-set to a higher amount or to your home currency, and restaurants without printed prices. Check the meter, always pay in local currency, and keep your bag in front of you in queues.

In Mexico (Quintana Roo), 10–15% in restaurants, 50–100 pesos a day for guides and dive crews, 20–50 pesos for bellhops. Breakfast until 11:00, lunch 14:00–16:00 and dinner from 19:30; beach kitchens close early, taquerías run late. Cover shoulders and knees inside churches, greet staff before ordering, keep your voice down in residential streets at night, and expect shops in smaller towns around Cozumel to close in the early afternoon.

Install Google Maps, Uber (Cancún and Playa del Carmen only), DiDi, ADO for intercity coaches, WhatsApp for every booking. Download an offline map of Cozumel before you land, and add your transport card or pass to your phone wallet if the local operator supports it.

Walk two or three streets off the main square or monument in Cozumel and look for a short handwritten menu, a full room of local voices, and prices displayed at the door. A daily menu chalked up at lunchtime is the strongest signal; a laminated menu in five languages with a host outside is the strongest warning.

Eat what Riviera Maya grows and lands: the signature rice, stew or grill of the region, whatever the market is selling that week, and the local wine or vermouth by the glass. The most honest versions are in the family-run place near the market of Cozumel, at lunch, when the daily menu is on.

Breakfast until 11:00, lunch 14:00–16:00 and dinner from 19:30; beach kitchens close early, taquerías run late. Book dinner for anything popular, ask for the bill (it won't arrive unprompted), and split payment is usually fine by card. 10–15% in restaurants, 50–100 pesos a day for guides and dive crews, 20–50 pesos for bellhops.

Do a single loop of the historic centre of Cozumel, stop at its one defining sight, then eat where locals eat near the market. That gives you the character of the place in three or four hours without a ticket queue eating the whole visit.

Free: the highest point of the old town, the bell tower terrace when it's open, and the bridge or promenade that looks back at Cozumel's skyline. Paid: a rooftop bar or tower ticket — worth it only if you arrive forty minutes before sunset to get the rail. Inland, the ridge or castle road above town gives the widest light.

ADO coaches link the whole coast cheaply; colectivos run Playa–Tulum all day; hire a car only for Bacalar, Valladolid and Chichén Itzá, and carry pesos for the toll road If your 3-day plan is mostly on foot in Cozumel with one excursion, buy singles or a multi-journey card and skip the tourist pass; if you're crossing the city several times a day or using it with museum entry included, a 48 h pass pays for itself.

Cozumel is safe by European standards; the real risks are opportunistic. Avoid empty industrial or station peripheries after midnight, unlit parks, and packed nightlife streets where phones disappear. Walk lit main streets, use a licensed taxi or ride-hailing app late at night, and share your route if you're travelling solo.

Buy something made nearby: reef-safe sunscreen you will actually use, Yucatecan recado and habanero, vanilla from Papantla, a hand-loomed hammock from Valladolid rather than a beachfront stall. The weekly market in Cozumel and a workshop with the maker on site beat any airport shop, and you're supporting the local trade rather than an importer.

Keep two indoor blocks in reserve: the main museum or cathedral of Cozumel, a market hall with food stalls, a long lunch, or a thermal bath or wine cellar in Riviera Maya. In extreme heat, invert the day — sights before 11:00, indoors from 14:00 to 18:00, and the evening back outside. Diving is good all year; May–June has the flattest water. Carnival in February is the biggest in the Mexican Caribbean.

Locals go where there's no ticket desk: the residential lanes just outside the walls of Cozumel early in the morning, the neighbourhood bar with four tables and one dish, the cemetery or convent garden that nobody photographs, and the hill road out of town at dusk. Ask the person serving you coffee where they eat on Sunday — in Riviera Maya that question opens more doors than any list.
