Ferry to Isla Mujeres: piers, prices and which boat to take

Isla Mujeres is a short, beautiful hop off Cancún — about 20 minutes by fast ferry. The crossing itself is simple; the only real decision is which pier you leave from, because that choice changes the price significantly. Here is the honest breakdown.

The piers (this is the key choice)

There are several departure points, and they are not priced the same:

• Puerto Juárez / Gran Puerto (downtown Cancún): the main, best-value departure point. Ultramar runs frequent fast catamarans from here at ~300 MXN round trip (~17 USD), ~20 minutes. There is also a cheaper, slightly slower public ferry from the adjacent Puerto Juárez dock at around half that price.
• Hotel Zone piers (e.g. El Embarcadero / Playa Tortugas / Playa Caracol): convenient if you are staying in the Hotel Zone, but markedly more expensive (often ~400–500+ MXN round trip) for the same island.

If you are watching your budget, get to Puerto Juárez/Gran Puerto and take Ultramar or the public boat. The Hotel Zone piers mainly buy you convenience.

Ultramar vs the public boat

• Ultramar: modern, fast catamarans, the most frequent departures (about every 30 minutes), clean terminals, ~20-minute crossing. The reliable default at ~300 MXN round trip.
• Public Puerto Juárez ferry: noticeably cheaper, a bit slower and less frequent, used more by locals. Fine if you want to save pesos and are flexible on timing.

Both arrive at the same central pier on Isla Mujeres, right in the town near the golf-cart rentals and Playa Norte.

Schedules

From Puerto Juárez/Gran Puerto, Ultramar runs roughly every half hour from early morning (~5–6am) until late evening (~last boats around 8:30–11:30pm depending on season). Confirm the current timetable and especially the last ferry back at the terminal, so a day trip doesn’t strand you on the island. The public ferry runs less often, so check its board separately.

Buying tickets and avoiding the markup

• Buy from the official Ultramar booths at the terminal, or the marked public-ferry window — not from touts nearby bundling “ferry + tour.”
• Around the docks, timeshare and excursion reps push “discounted” ferry packages tied to a sales pitch; skip them and buy direct.
• Pay in pesos; choose MXN if a card terminal offers USD.
• A round-trip ticket is convenient but ties you to one operator’s return; one-ways keep you flexible.

Getting to Puerto Juárez from the Hotel Zone

• R-1 bus runs from the Hotel Zone to downtown Cancún (~12 MXN); ask for Puerto Juárez or transfer to a short taxi.
• Taxi from the Hotel Zone to Puerto Juárez: ~150–250 MXN.
• From Cancún airport, take ADO or a shuttle to downtown first, then reach the pier.

Even with a short taxi to the cheaper pier, you usually come out ahead of paying the Hotel Zone ferry premium.

On the island

Isla Mujeres is small — about 7 km long — and best explored by golf cart (~900–1,200 MXN/day) or scooter; taxis are cheap too. Playa Norte at the north end is one of the finest beaches in the region and an easy walk from the ferry pier. A half-day works, but the island rewards a relaxed full day.

Highlights to lap with a golf cart include Punta Sur at the southern tip (cliffs, a small Maya shrine and sculpture park, the easternmost point of Mexico), the wild eastern coast road, and the calmer turquoise swimming at Playa Norte in the north. The town centre near the pier is compact, with restaurants, golf-cart rentals and shops within a few blocks. Golf carts go quickly in high season, so rent early in the day; you will usually leave a deposit and your ID.

Cost of a day, roughly

A relaxed independent day adds up to:

• Ferry round trip: ~300 MXN (Ultramar) or ~150 MXN (public boat).
• Bus/taxi to the pier: ~12 MXN (R-1) to ~250 MXN (taxi from Hotel Zone).
• Golf cart: ~900–1,200 MXN/day split among your group, or a few taxi hops for less.
• Food and a beach club lounger: ~300–600 MXN per person depending on choices.

Done on the ferry and a shared golf cart, Isla Mujeres is one of the better-value days out from Cancún.

Planning an Isla Mujeres day trip

Isla Mujeres makes a near-perfect day trip, and the short crossing means you lose little time getting there. A simple plan:

1. Reach Puerto Juárez/Gran Puerto by R-1 bus or taxi and take an early Ultramar ferry (~8–9am) to beat the day-tour boats.
2. On arrival, rent a golf cart to lap the small island — the south point (Punta Sur) and the eastern cliffs are worth the loop.
3. Spend the middle of the day at Playa Norte, an easy walk from the pier and one of the finest beaches in the region.
4. Return on an afternoon or early-evening ferry, checking the last sailing before you relax too long.

Ferry vs an organised boat tour

Note the difference between the scheduled passenger ferry (you go independently, set your own pace, cheapest) and the many catamaran/booze-cruise day tours sold from Cancún that include the crossing, open bar, snorkel stop and lunch. The tours are fun and social but pricier and tightly scheduled, often crowding Playa Norte at midday. If you want freedom and value, take the regular ferry and explore on your own; if you want a guided party day, the catamaran tours exist for that.

Practical tips

• The crossing is short but can be breezy; hold onto hats and sunglasses on the open deck.
• Bring sun protection, water and small pesos for golf carts and beach clubs.
• Go early to beat the day-tour crowds at Playa Norte.
• Mind the last ferry back if you are not staying overnight.
• A golf cart is the fun way around, but the island is small enough that taxis are cheap if you would rather not drive.

Bottom line

The cheapest reliable way to Isla Mujeres is the Ultramar or public ferry from Puerto Juárez/Gran Puerto (~300 MXN round trip, or about half on the public boat), not the pricier Hotel Zone piers. Buy direct in pesos, ignore the tour touts, check the last sailing, and you have one of the easiest, best-value island trips in the whole region.
