On Symi, a boat is not only an excursion; it is one of the most useful ways to understand the island. Roads reach parts of the coast, but steep cliffs and narrow coves make the sea the natural route to beaches such as Nanou and Agios Georgios. Nearby islets including Nimos, Sesklia and Agia Marina add another layer to the day.
Visit Greece specifically recommends sea excursions around Symi and describes Nimos as a wildlife sanctuary, Sesklia for clear water and springs, and Agia Marina for glass-like sea. The practical challenge is choosing between a simple beach taxi, a shared multi-stop excursion and a private boat. The best option depends on whether you value flexibility, price or the number of stops.
Taxi boat or full excursion: choose by your real priority
A taxi boat is ideal when you want to spend most of the day at one beach. You travel out, agree or confirm the pickup time and avoid a timetable packed with short stops. This works particularly well for Nanou or another serviced cove where you are happy to swim, read and have lunch.
A full excursion is better when the coastline itself is the attraction. You may see cliffs, remote bays and islets that are difficult to appreciate from land. Read the itinerary carefully: two tours with the same duration can offer very different swimming time.
Nanou: a classic beach-taxi day
Nanou combines dramatic enclosing slopes, clear water, large pebbles and enough space to feel away from the town. It is one of the easiest introductions to a boat-access Symi beach because you can make the cove the main destination rather than treating it as a quick photo stop.
Ask about current facilities before departure and still carry water. Confirm the last pickup. If you are prone to seasickness, sit where fresh air is good and consider whether afternoon wind might make the return bumpier.
Agios Georgios: go for the approach as much as the beach
The vertical limestone wall behind Agios Georgios Dysalonas is the reason the cove stands out. Visit Greece gives a height of about 350 metres. Approaching by sea reveals the scale gradually, which is far more impressive than seeing another photograph online.
Because the setting is exposed and natural, listen to the skipper’s instructions about where the boat can land or anchor. Do not wander beneath unstable cliffs or assume every part of the shore is safe. Water, shade and return arrangements matter more than beach facilities.
Agia Marina: clear-water stop close to the main island
Agia Marina is often included in swimming itineraries because of the clarity of the water and the small-island atmosphere. It can work as one stop on a multi-cove day rather than a full-day destination. Conditions and access arrangements vary with the boat you choose.
If your priority is snorkelling, ask the operator whether enough time is allowed to get in the water rather than simply photograph the bay. Bring your own mask if fit matters to you; shared gear availability should never be assumed.
Sesklia: a quieter islet experience
Visit Greece highlights Sesklia among the offshore excursions and mentions clear water and natural springs. It is a good example of why a boat day on Symi is about more than beaches: the sense of leaving the inhabited coast is part of the experience.
Respect archaeological and environmental restrictions on the islets. Do not remove shells, stones or plants, and follow the skipper’s guidance about where landing is permitted. Pack all rubbish back to the boat.
Nimos: treat a wildlife sanctuary carefully
Nimos is described by Visit Greece as a wildlife sanctuary. That means the goal is not to turn every cove into a party stop. Keep music low, avoid disturbing animals and follow any landing restrictions. The island’s value is precisely that it feels less developed.
Photographers should bring a longer lens rather than moving close to wildlife. A responsible excursion protects the quiet character that visitors came to experience in the first place.
Private boat rental: freedom comes with responsibility
The Municipality of Symi lists rental-boat operators, but a private boat is not automatically the best choice for everyone. Experience, licence requirements, insurance, fuel policy, weather knowledge and mooring rules all matter. If you are not confident, hire a skipper or join an organised trip.
Even experienced boaters should ask about local hazards and restricted areas. The cliffs that make Symi beautiful also create wind effects and limited landing points. Do not copy another boat’s route simply because it appears easy.
Plan for sun, water and motion
A full day on the water produces more sun exposure than many people expect because light reflects from the sea. Use high-SPF sunscreen, a hat that will not blow away and a shirt or rash vest for long periods. Drink water before you feel thirsty.
If you get seasick, take preventive measures early rather than waiting until the boat is moving. Sit facing forward with fresh air and avoid a very heavy breakfast. Children need shade, snacks and a realistic amount of swimming time rather than an adult sightseeing schedule.
Getting there and getting around
Gialos is the main place to compare boat options, while Pedi can also be useful for nearby beach access. Go to the departure point early enough to identify the correct boat; several vessels may leave around similar times. Keep the operator’s contact details and ask whether payment must be cash or card.
Weather can change the itinerary or cancel a trip. Do not book a non-refundable plan for the same afternoon that depends on the boat returning at an exact minute. Leave a buffer before ferries, restaurant reservations or airport connections.
Best time to go
June through September offers the most reliable boat-trip season, with July and August providing the largest choice but also stronger heat and more demand. June and September are often ideal if you want warm swimming without peak crowds.
Morning departures can be calmer on many days, though local wind patterns matter more than a generic rule. Ask operators what conditions are expected and be willing to shift the boat day if the forecast is poor.
Where to stay
Gialos is the most convenient base if boat trips are a major part of your holiday because you can compare departures and reach the quay easily. Pedi is attractive for a quieter stay with access to nearby coves. Chorio requires more transport down to the sea but compensates with atmosphere.
If you are taking an early excursion, staying near the departure point the previous night removes unnecessary stress. Check exact meeting points because “Symi harbour” can still cover a long waterfront walk.
Food, water and useful stops
Some excursions include food, a barbecue or drinks; others include nothing. Read the inclusions rather than guessing from the price. Carry your own water and a snack even when lunch is promised, especially with children or dietary restrictions. Never count on finding a taverna at every remote stop.
A realistic way to plan the day
- Simple beach taxi: choose one cove such as Nanou, confirm the final pickup and spend most of the day swimming and relaxing.
- Scenic shared excursion: prioritise a route with Agios Georgios plus two or three meaningful swim stops rather than the longest possible list.
- Islet day: choose an itinerary including Agia Marina, Sesklia or Nimos if offshore scenery interests you more than staying on one beach.
- Private boat: use only if experience, licensing and local conditions are appropriate; otherwise hire a skipper.
Mistakes to avoid
- Booking a tour because it has the most stops without checking actual swimming time.
- Failing to confirm the final return on a beach-taxi service.
- Assuming lunch, snorkelling gear or shade are included.
- Scheduling an important ferry too close to a boat-trip return.
- Renting a boat without understanding local licence and insurance requirements.
- Disturbing wildlife or ignoring landing restrictions on protected or archaeological islets.

Frequently asked questions
What is the difference between a taxi boat and an excursion boat?
A taxi boat usually takes you to one beach and collects you later. An excursion boat follows a multi-stop route and keeps the group on a timetable.
Which boat-access beach is most dramatic?
Agios Georgios Dysalonas is the standout for cliff scenery, while Nanou is a classic option for spending a longer beach day.
Can I visit Nimos and Sesklia?
Boat excursions may include them depending on season, permissions and conditions. Follow environmental and archaeological restrictions.
Should I book Symi boat trips in advance?
In peak summer, booking popular excursions ahead can be sensible. In shoulder season, confirm that the route is actually operating before organising the rest of the day around it.

Final planning advice
A good Symi boat day is not measured by how many coves you tick off. Decide whether you want one long beach stop, dramatic coastline or offshore islets, then choose the boat that gives enough time for that experience. Confirm return times, protect yourself from the sun and let the skipper adjust the plan when sea conditions demand it.
