Panama Canal Cruise Guide: Full and Partial Transits Explained

Overview

The Panama Canal is the only cruise destination where the highlight is a piece of infrastructure, and it earns that status. Watching a 900-foot ship rise 85 feet through three lock chambers, with the walls close enough to touch from a balcony, is genuinely remarkable, and it takes most of a day.

The critical distinction is between a full transit and a partial transit. A full transit crosses ocean to ocean, taking 14 to 16 nights and finishing in a different country from where it started. A partial transit enters the canal from the Caribbean side, ascends into Gatun Lake, then reverses back out and continues a round-trip Caribbean cruise.

Partial transits are cheaper and shorter and give you the Gatun Locks experience, which is the visually impressive part. Full transits give you the whole crossing, the Culebra Cut and the Pacific-side Miraflores Locks, plus a genuinely different itinerary on each coast.

The canal runs 82 kilometres between Colon on the Caribbean side and Panama City on the Pacific. Ships are raised 85 feet to Gatun Lake through a series of locks, cross the lake and the Culebra Cut, then descend back to sea level on the other side.

Two lock systems operate. The original 1914 locks handle Panamax ships up to about 106 feet wide. The Neopanamax locks, opened in 2016, handle much larger vessels. Most cruise ships still use the original locks, and this is what you want: the chambers are narrower, so the walls are close and the experience is far more dramatic.

Ships built specifically to fit the original locks, such as Coral Princess and Island Princess, are known as Panamax ships. Larger vessels using the Neopanamax locks sit in the middle of a much wider chamber and the effect is diminished.

• Ships rise 85 feet to Gatun Lake and descend again on the far side.
• The original 1914 locks give a much better experience than the newer Neopanamax locks.
• Full transit takes eight to ten hours; partial transit about six.
• Transit day begins before dawn, usually around 5.30am.

The best time to go

Panama has a pronounced dry season from mid-December to mid-April and a wet season for the rest of the year. The difference is dramatic: the wet season delivers heavy afternoon downpours most days, and standing on deck for eight hours in that is unpleasant.

January through March is the recommended window, and it is also when most cruise lines schedule their transits.

The ports, honestly assessed

Panama Canal itineraries pair the transit with Central American and Caribbean ports. The transit is the point; the ports are supporting material, though several are genuinely good.

• ColonPanama

  The Caribbean-side entry. The Gatun Locks visitor centre and the Panama Canal Railway are the two worthwhile excursions.

• Fuerte AmadorPanama

  The Pacific-side anchorage serving Panama City. Casco Viejo, the old quarter, is excellent and a 20-minute taxi.

• Puerto LimonCosta Rica

  Rainforest aerial trams and Tortuguero canals. One of the better wildlife port days in the region.

• PuntarenasCosta Rica

  The Pacific-side Costa Rica call. Manuel Antonio National Park is a long transfer but is the best wildlife day of the cruise.

• CartagenaColombia

  The best port on any Panama Canal itinerary. The walled old city is a UNESCO site and walkable from a short taxi.

• CorintoNicaragua

  Leon and the colonial churches, plus volcano boarding at Cerro Negro for the adventurous.

• HuatulcoMexico

  A Pacific-side call on westbound transits. Nine bays, good snorkelling, low-key.

• Cabo San LucasMexico

  The final call before Los Angeles on most westbound transits. Tender port.

Weather, month by month

Panama sits nine degrees north of the equator, so temperature barely varies. Rainfall does, enormously, and it is the only weather variable that matters for a transit.

What it actually costs

Panama Canal cruises are priced by length rather than by destination premium, so a 15-night full transit costs less per night than a seven-night Caribbean sailing on the same line.

The hidden cost is the one-way structure. A full transit ends in a different city from where it started, so you need two separate flights rather than a round-trip, which typically adds $150 to $350 per person.

Travel tips from our sailings

• 1

  Choose a ship that uses the original 1914 locks. Panamax vessels such as Coral Princess sit within a few feet of the chamber walls, which is the whole experience.

• 2

  Transit day starts around 5.30am. Set an alarm, get coffee early and claim a forward-facing spot before the crowd.

• 3

  A forward-facing cabin or a wraparound aft balcony is worth booking specifically for transit day.

• 4

  Bring binoculars. The Culebra Cut and the lock machinery reward them.

• 5

  The Panama Canal Railway excursion from Colon runs alongside the canal and is the best excursion on the itinerary.

• 6

  Cartagena is the best port on the route and deserves a full day. The walled city is walkable and a guide costs about $40 for a half day.

• 7

  Full transits are one-way, so book flights into one city and out of another and check the cost before committing.

Panama Canal packing essentials

• A wide-brimmed hat and high-factor sunscreen; you will be on an open deck for eight hours near the equator.
• Binoculars, which are genuinely useful for lock machinery and Culebra Cut wildlife.
• A light rain shell for any sailing outside January to March.
• Insect repellent for Costa Rica and Panama rainforest excursions.
• Comfortable shoes for Cartagena's cobbled old city.
• A refillable water bottle; deck days in Panama are dehydrating.
