As mentioned above, this excursion costs only a little more than the additional tax for cruise ships that pass into and back out of the Gatun locks, and costs only a little more than the same excursion when booked ashore, which we did not risk due to the tight schedule. For us this excursion was very enjoyable and worth every penny. In fact, it was the first time in 20 cruises that we booked an excursion through our cruise line rather than traveling independently. Being on a small ferry rather than a large ship makes the canal engineering all the more impressive, and the ferry transits two sets of locks and travels all the way to the Pacific.
We did not spend any time in the city of Colon itself, but the cruise terminal has a pleasant sheltered market for souvenir shopping, including handicrafts from the local Indians. Their embroidery is famous and makes excellent, easy-to-pack pillow covers and shirt appliques.
Our fourth port was CARTAGENA Columbia, the historic center of which is a UNESCO World Heritage Site. Unfortunately, some passengers were spooked by the reputation of Columbia and did not leave the ship. They missed one of the most photogenic cruise ports in the western hemisphere.
We made an effort to go ashore as soon as the ship was cleared, and we were glad we did. The town was wonderfully peaceful for several hours until it began to fill with tour groups from our ship and from the QE2, which was docked with us. Street vendors will offer their wares but will not pressure you if you politely decline. Remember that they are simply trying to earn a living and merit your respect.
Cartagena has a very pleasant cruise terminal with a free shuttle from the ship and a taxi stand just outside. A taxi ride for three people to the old town clock tower gate costs a standard $15 US. The price is posted at the taxi stand, but should be confirmed with the driver before entering the taxi. Make certain that the driver takes you up to the gate and does not drop you a few blocks away at the convention center. Return taxis are easy to find, and when metered they are less than $15 for the return trip.
For those who prefer, local English speaking guides are available in the town and via the internet. They can add interesting information and a sense of security, but we preferred to wander on our own and were quite comfortable doing so. We even came across a movie being filmed near the town walls.
Our fifth port was COZUMEL. This can be a hectic port – when there I counted seven other cruise ships, together off-loading more than 15,000 passengers. To avoid the crowds we simply snorkeled from a dive shop that was a short walk north of our cruise dock (the most southerly of the three Cozumel cruise docks).
While eating a late breakfast, we noticed several snorkel tour boats tied up not far from our ship. Assuming that the locals know the best snorkel spots, we walked north along the shore to a nearby dive shop diagonally across from the large thatch roof pyramid in front of one of the hotels. The dive shop is in a small whitewashed building down a short drive adjacent to a walled resort beach. It offers free lockers (bring your own padlocks), a changing area, and an easy water entry.
In the past we had taken taxis to various snorkel spots south of San Miguel town, but this snorkel site was just as enjoyable and could not have been more convenient. Those who want to relax on a beach, however, will still need to take a taxi several miles south.
Have a wonderful cruise and happy port adventures!
