More about: 4 Best Boat Tours and Cruises in Athens
Greece has more than 2,000 islands, and although not all of them can be visited on excursions from Athens (you would need to take a flight), there are some islands that you can visit on a one-day cruise from Athens.
1. One-day cruise to Hydra, Poros, and Aegina from Athens

With this one-day cruise from Athens, a vehicle will pick you up at your hotel and take you back once the excursion is over. You will visit three islands and spend between one and two hours on each one, but the cruise itself will also be an experience in itself. The islands you will see are the closest to Athens, located in the Saronic Gulf:
Hydra
A small island with a bustling commercial center where you will find beautiful colorful houses, breathtaking landscapes, and wonderful beaches. Your guide will tell you the history of a place that once served as a refuge for pirates.
Poros
In the center of the island, on a hill, are the remains of the temple of Poseidon, and you can also visit places such as the lemon grove, but I recommend taking a stroll around the port while admiring the scenery.
Aegina
Once there, you can take a stroll through the city or go on an excursion to the Temple of Aphaia, which is quite popular in Greece.
What this cruise includes
- Expert advice from a guide
- A Greek buffet lunch
- A folklore show during the cruise
2. Boat trip to Agistri, Aegina and Moni from Athens

The atmosphere on board is another of the great attractions of this experience. With chill-out music, snacks, drinks, and a full Greek lunch, you'll spend an unforgettable day on the high seas. If you're in the mood for a little extra adventure, you can join an optional bike tour of Agistri Island (paid separately). Everything is designed so you can experience the essence of the Aegean Sea like a local.

Tips for your cruise around the Greek Islands from Athens

The main purpose of day cruises departing from Athens is to give you the opportunity to get to know the Greek landscape and some of its islands in more detail. In other words, the beaches are not the main attraction of this boat trip. This is the first thing you should bear in mind before booking the experience so you don't end up disappointed.
How to choose the right cruise
If you've taken a quick look at what's available, you'll have seen that there are dozens of similar cruises departing from Athens. How do you decide which tour to choose? My advice is to consider a number of factors:
- The price: These types of excursions are not cheap, but you don't necessarily have to pay an excessive amount to enjoy them.
- Free cancellation: you always have to consider unforeseen circumstances. Choose a tour that gives you the security of being able to cancel 24 hours in advance without losing your money.
- Time on the islands: the greatest added value of a day cruise is being able to make the most of your time. Before booking, check the estimated time you will spend on each of the islands included in the tour.
- Services included: being able to enjoy the journey between the different stops is also important. Many tours offer on-board services such as food or entertainment so that your time on the boat is part of the experience.
What to bring on the cruise
Finally, remember to bring everything you need to spend the day in maximum comfort. Sunscreen is important, as well as a swimsuit in case you get the chance to go for a swim, and comfortable clothes and shoes. You won't need much else during the trip.
Other Greek islands worth visiting

If a one-day round-trip cruise isn't enough for you, there are many more options for enjoying the Greek islands. Before booking your accommodation in Athens, consider spending a night away on a multi-day tour or even organizing your own trip. This will allow you to visit islands further away from the capital, such as:
Santorini
With excellent beaches, nightlife, and a landscape of white houses scattered across a mountain, this is the ideal place for any travel photographer.
Mykonos
Known for its parties and nightlife. You can get there by plane and from there hop over to other nearby islands. Or you can sign up for an excursion to Mykonos from Athens.
Paxos
Close to Corfu. Relaxation and privacy are guaranteed, and it won't be too crowded because it's only accessible by boat.
Rhodes
Ideal for spending a few days enjoying both its landscapes and tourist attractions such as Monolithos Castle and the Epta Piges natural park.
Crete
This is Greece's largest island and could be another place to start your trip around the country. In addition to landscapes and beaches, you can visit important archaeological sites.
