Navigating the Ports

Departure Port (Kos)

Kos Port is located in Kos Town on the northeastern coast of the island. The main ferry terminal is conveniently situated near the centre of Kos Town, making it easily accessible for travellers. If you're staying in Kos Town, you can likely walk to the port in 10-15 minutes from most accommodations.

For those staying further away, local buses connect various parts of the island to Kos Town, and taxis are readily available. If you're renting a car during your stay, there is parking available near the port area, though spaces can be limited during peak season.

The port itself is well-equipped with basic facilities including waiting areas, toilets, and a few cafés and shops where you can purchase last-minute supplies or enjoy a refreshment before boarding. There's also a tourist information desk where you can get maps and information about both Kos and your destination.

It's recommended to arrive at least 30-45 minutes before your scheduled departure time to allow for a smooth check-in process. The boarding procedure is typically straightforward, with foot passengers usually boarding just before departure.

Arrival Port (Kalymnos)

The main port of Kalymnos is located in Pothia, the island's capital and largest settlement. When arriving from Kos, your ferry will dock at the main harbour, which is centrally located and serves as the hub of activity on the island.

Upon disembarking, you'll find yourself right in the heart of Pothia. The town centre is within easy walking distance, with numerous shops, restaurants, and accommodations just minutes away from the port.

For transportation around the island, there are several options available. Local buses connect Pothia to other villages and beaches on Kalymnos, with the bus station located near the port. Taxis are available for direct transfers to specific destinations, and you'll typically find them waiting near the ferry arrival area.

For more independence, scooter and car rental agencies can be found near the port, offering daily and weekly rental options. This is a popular choice for visitors wanting to explore the island at their own pace.

The port area itself has several amenities including cafés, shops, and tourist information points where you can gather maps and local advice. You'll also find ATMs, a pharmacy, and small supermarkets within walking distance for any immediate needs upon arrival.

Day Trip Possibilities

A day trip from Kos to Kalymnos is not only feasible but highly recommended for travellers based in Kos who want to experience another beautiful Dodecanese island without changing accommodations. With the ferry journey taking just 35-37 minutes each way and multiple daily sailings, you can easily enjoy a full day exploring Kalymnos.

For an ideal day trip, consider taking an early morning ferry from Kos, which would get you to Kalymnos by mid-morning. With departures starting as early as 00:20 and running throughout the day until 22:20, you have flexibility in planning your schedule.

A sample itinerary might look like this: Depart Kos on a morning ferry, arrive in Pothia (Kalymnos Town), spend the morning exploring the harbour area and perhaps visiting the Archaeological Museum. Enjoy lunch at one of the authentic tavernas along the waterfront, then take a local bus or taxi to Vathys or Massouri in the afternoon to see a different part of the island. If you're feeling adventurous, Kalymnos is world-famous for rock climbing, and you could book a beginner's session with a local guide. Return to Pothia in time for an evening ferry back to Kos.

The frequent ferry connections make this day trip quite straightforward, but it's still advisable to check the return schedule carefully, especially during off-peak seasons when services may be reduced. During summer months, the last ferry typically leaves late enough to allow for dinner in Kalymnos before returning.

If you're concerned about being constrained by ferry schedules, consider booking a guided day tour from Kos to Kalymnos, which will handle all the transportation logistics and often includes visits to the island's highlights with a knowledgeable guide.

Things to Do in Kalymnos

Kalymnos offers a diverse range of attractions and activities that cater to all types of travellers. Here are the top five attractions you shouldn't miss:

1. Pothia (Kalymnos Town)

The island's capital is a colourful, vibrant port town with neoclassical buildings and narrow alleys. Visit the Archaeological Museum to learn about the island's history, and the Maritime Museum to discover Kalymnos' rich sponge-diving heritage. The town is best explored in the morning or late afternoon, with most attractions open from 8:00 to 15:00.

2. Climbing in Massouri

Kalymnos has become world-famous as a rock climbing destination, with over 3,000 routes of varying difficulty. Even if you're a beginner, several schools offer single-day courses. The climbing area in Massouri offers spectacular views across to the island of Telendos. Climbing schools operate throughout the day, but early morning or late afternoon sessions are recommended to avoid the midday heat.

3. The Valley of Vathys

This fertile valley surrounded by mountains is one of the most beautiful spots on the island. Known for its citrus orchards, it offers a glimpse into traditional Greek agricultural life. The valley is accessible year-round and is particularly beautiful in spring when the trees are in bloom.

4. Castle of Chrysocheria

Perched on a hill above Pothia, this medieval castle offers panoramic views of the town and harbour below. The climb up takes about 30 minutes but rewards visitors with spectacular photo opportunities. The castle is open daily from sunrise to sunset, with no admission fee.

5. Beaches

Kalymnos boasts several beautiful beaches, with Massouri, Myrties, and Kantouni among the most popular. These beaches offer clear waters perfect for swimming and snorkelling, along with beachside tavernas for refreshments. Most beaches have facilities open from morning until sunset, with water sports equipment available for rent during the summer season.

Neighbourhood Guide

Pothia, the main port and capital, is where most of the island's commercial activity takes place. Here you'll find the greatest concentration of shops, restaurants, and historical sites, including the Archaeological Museum and the Church of Christ.

Massouri and Myrties on the west coast have developed into the island's main tourist areas, offering stunning views of Telendos island, numerous accommodations, and access to the famous climbing routes. These areas have a more cosmopolitan feel with international restaurants and climbing shops.

Emporios and Vathys represent the more traditional side of Kalymnos, with authentic villages where you can experience local life and cuisine away from the tourist crowds. These areas are perfect for those seeking a more authentic Greek island experience.

For nightlife, Pothia offers the most options with several bars and tavernas that stay open late, especially during summer. Massouri also has a good selection of bars catering to the international climbing community.

Weather in Kalymnos

Kalymnos enjoys a typical Mediterranean climate with long, hot summers and mild, relatively wet winters. The island experiences over 300 days of sunshine annually, making it a popular destination throughout much of the year.

Summer (June to September) sees average temperatures ranging from 25°C to 35°C (77°F to 95°F). July and August are the hottest months, with very little rainfall and plenty of sunshine. These conditions are perfect for beach activities and swimming in the crystal-clear Aegean waters, though midday heat can be intense.

Spring (April to May) and autumn (October to November) offer milder temperatures between 15°C and 25°C (59°F to 77°F), making these seasons ideal for outdoor activities like hiking and rock climbing. These shoulder seasons also tend to be less crowded while still offering pleasant weather.

Winter (December to March) is the coolest and wettest period, with temperatures typically ranging from 8°C to 15°C (46°F to 59°F). While not ideal for swimming, winter still offers many clear, sunny days perfect for exploring the island's cultural attractions and villages.

Regarding ferry operations, the weather generally has minimal impact during summer months, with services running reliably. However, during winter, particularly between November and February, strong winds can occasionally cause ferry delays or cancellations. If travelling during this period, it's advisable to build some flexibility into your schedule and check weather forecasts before your journey.

Cost of Visiting Kalymnos

Kalymnos offers good value compared to more famous Greek islands, making it an attractive destination for budget-conscious travellers as well as those seeking more comfort.

For budget travellers, daily expenses can be kept to around £50-70 per day, including basic accommodation in a guesthouse (£25-40), meals at local tavernas (£8-15 per meal), and some activities. Street food options like souvlaki or gyros cost around £3-5.

Mid-range travellers should budget approximately £90-130 daily, covering comfortable hotels (£50-80), dining at better restaurants (£15-25 per meal), and activities like guided tours or boat trips.

Public transportation on the island is affordable, with local bus fares costing around £1.50-2.50 per journey. Renting a scooter costs approximately £15-20 per day, while car rentals start at about £30-40 daily.

To save money, consider staying in Pothia rather than the more tourist-oriented Massouri area, eat where the locals eat (usually away from the main harbour front), and take advantage of the many free activities like hiking and visiting beaches. Many accommodations also include breakfast, which helps reduce daily food costs.

Best Time to Visit Kalymnos

The peak tourist season in Kalymnos runs from June through August, coinciding with the hottest weather and school holidays across Europe. During this period, you'll find the fullest range of services, with all restaurants, shops, and activities operating at maximum capacity. However, this is also when the island is most crowded and accommodation prices reach their highest point. Temperatures regularly exceed 30°C (86°F), which can make outdoor activities challenging during midday hours.

The shoulder seasons of late April to early June and September to October offer what many consider the ideal balance. During these months, you'll enjoy warm weather suitable for swimming and outdoor activities, with temperatures typically ranging from 20-28°C (68-82°F). There are fewer crowds, accommodation prices drop by 20-30%, and the island maintains a lively atmosphere while feeling less overwhelmed by tourism.

For rock climbers, the spring (April-May) and autumn (September-October) seasons are particularly favoured due to cooler temperatures that make climbing more comfortable.

The winter off-season (November to March) sees many tourist facilities close, but offers a glimpse into authentic local life. While swimming might be too cold for most, winter visitors can enjoy hiking, cultural experiences, and significantly lower prices. This period is ideal for travellers seeking tranquility and an authentic Greek island experience away from tourism.

Notable events include the Climbing Festival in October, which attracts climbers from around the world, and the Easter celebrations in spring (dates vary), featuring traditional processions and customs. The Feast of Saint Savvas on December 5th offers insight into local religious traditions.
