Quick Answer
The best overall way to get from Castello to Marco Polo Airport is the Alilaguna Blue Line water bus from the Arsenale stop. It costs €15 (≈ $16 USD), takes 70–80 minutes, and runs directly to the airport terminal with no transfers. For speed, a water taxi costs €100–€130 (≈ $109–$142 USD) and takes just 30–40 minutes. For budget travelers, the vaporetto + ACTV bus combo costs only €13.50 (≈ $15 USD) but requires one change at Piazzale Roma.
1. Alilaguna Water Bus – Direct, Scenic & Reliable
The Alilaguna water bus is the most popular choice for travelers staying in Castello who want a direct, no-transfer connection to Marco Polo Airport. Unlike the regular ACTV vaporetto network, Alilaguna is a dedicated airport and lagoon shuttle service that operates on two main lines serving Castello: the Blue Line (Linea Blu) and the Red Line (Linea Rossa).
Blue Line (Linea Blu) – Best for Castello
The Blue Line departs from the Arsenale stop (located in the heart of Castello, a 5-minute walk from Via Garibaldi) and also calls at Giardini Biennale before heading directly to the airport. Total journey time from Arsenale to the airport terminal is 70–80 minutes. The first departure from Arsenale is around 4:45 AM and the last at 11:30 PM, with departures every 30–40 minutes during daytime.
Red Line (Linea Rossa) – Alternative from San Zaccaria
The Red Line serves San Zaccaria (at the western edge of Castello, near Piazza San Marco) and reaches the airport in 55–65 minutes. This is a good option if you are staying near the waterfront west of Via Garibaldi. Frequency is similar to the Blue Line.
Ticket Prices & Purchase
- Single ticket: €15 (≈ $16 USD) per person, including one piece of cabin luggage. Additional large bags may incur a small surcharge.
- Return ticket: €27 (≈ $29 USD), valid for 7 days.
- Tickets can be purchased at Alilaguna ticket desks at Arsenale, San Zaccaria, and online via the official Alilaguna website.
- You can also buy tickets at tabacchi (tobacco shops) displaying the Alilaguna logo, or at the Venice Airport arrival hall.
Boat Features & Luggage
Alilaguna boats are larger than standard vaporettos and have dedicated luggage racks inside the cabin. Seating is both indoor and outdoor (open deck). The boats are wheelchair-accessible, but boarding at some stops may require crossing a small gap. During acqua alta (high water) events, services may be delayed or rerouted – always check the real-time status before leaving.
Pros & Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Direct route – no transfers | Slower than water taxi (70–80 min) |
| Scenic lagoon views along the way | €15 is relatively pricey compared to public bus |
| Luggage racks and comfortable seating | Limited night service (last boat ~11:30 PM) |
| Frequent departures (30–40 min intervals) | Can be crowded during peak season |
Verdict: The Alilaguna Blue Line from Arsenale is the best balance of convenience, cost, and experience for most travelers leaving Castello. Book tickets online in summer to avoid queues.

2. Water Taxi – Fastest & Most Luxurious
For travelers who prioritize speed, privacy, and comfort, a private water taxi is the premium option from Castello to Marco Polo Airport. A water taxi picks you up directly from any pier in Castello (including hotel docks, private residences, or public landing stages) and takes you straight to the airport water terminal, which is a short covered walkway from the check-in hall.
Travel Time & Cost
- Journey time: 30–40 minutes (weather dependent).
- Price range: €100–€130 (≈ $109–$142 USD) for up to 4–5 passengers with standard luggage. Prices rise after 9 PM and during peak season (May–September).
- Some companies charge extra for more than 3 large suitcases or for oversized items like sports equipment.
How to Book
Water taxis can be booked in advance through official Venice water taxi companies such as Venezia Taxi, Consorzio Motoscafi, or Alilaguna Taxi. You can also book via ride-hailing apps like Welcome Pickups or Booking.com Transfers. Always confirm the total price before boarding to avoid surprises.
When a Water Taxi Makes Sense
- Late-night or early-morning flights (when Alilaguna and buses are not running).
- Traveling with heavy luggage, elderly passengers, or small children.
- Groups of 3–5 people – the per-person cost can be as low as €25–€30, making it competitive with Alilaguna.
- Business travelers who value time savings and a stress-free experience.
Pros & Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Fastest option (30–40 min) | Expensive (€100–€130) |
| Door-to-door service from your pier | Subject to weather and high-water delays |
| Private, comfortable, and flexible | Must be pre-booked at peak times |
| Ideal for groups splitting the cost | Not all companies accept card payments onboard |
Verdict: Choose a water taxi if you have a tight schedule, heavy bags, or a group to share the cost. It’s the most efficient way to reach the airport from Castello.

3. Vaporetto + Airport Bus – Most Economical
Budget-conscious travelers can combine a regular ACTV vaporetto with an ATVO or ACTV airport bus for the cheapest possible route from Castello to Marco Polo Airport. Although it involves one change at Piazzale Roma (the main bus terminal in Venice), the total cost is significantly lower than the direct water options.
Step-by-Step Instructions
- From Castello, take an ACTV vaporetto (line 2, 4.2, or 5.2) to Piazzale Roma. Recommended boarding stops: San Zaccaria (lines 2, 4.2) or Arsenale (line 4.2). Journey time: 15–25 minutes. Ticket price: €7.50 (≈ $8 USD), valid for 75 minutes including one transfer.
- At Piazzale Roma, exit the vaporetto and walk to the airport bus terminal (signposted “Aeroporto” – 2-minute walk).
- Board the ATVO Express Bus (blue buses, €8, ≈ $9 USD, 20 minutes) or the ACTV Bus 5 (orange buses, €6, ≈ $6.50 USD, 25–30 minutes). Both drop you at the airport departure level.
Total cost: €13.50 (≈ $15 USD) via ACTV bus, or €15.50 (≈ $17 USD) via ATVO express. Total time: 50–65 minutes (excluding waiting time).
Which Bus Should You Choose?
| Bus Type | Price | Time | Frequency | Best For |
|---|---|---|---|---|
| ATVO Express | €8 (≈ $9 USD) | 20 min | Every 15–20 min | Speed and comfort; luggage storage underneath |
| ACTV Bus 5 | €6 (≈ $6.50 USD) | 25–30 min | Every 20–30 min | Budget; slightly slower but still reliable |
Pros & Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Cheapest option (€13.50–€15.50) | Requires one transfer at Piazzale Roma |
| Frequent departures on both vaporetto and bus | Vaporetto can be crowded with luggage |
| Works well for solo travelers and backpackers | Not ideal for very heavy or bulky luggage |
| Buses run from early morning (4 AM) to late night (midnight) | Total time can exceed 75 min with waiting |
Verdict: The vaporetto + bus combo is the best value for money if you’re comfortable with one transfer and traveling light. It’s ideal for solo travelers, students, and anyone on a strict budget.

4. Private Transfer – Premium & Stress-Free
A private transfer combines a water taxi from Castello to the Tronchetto or Piazzale Roma car park with a private car or minivan to the airport. While more expensive than public options, it offers the highest level of convenience for families, groups, or travelers with special needs.
How It Works
- A private driver meets you at your Castello accommodation or a designated pier.
- You take a private water transfer to Piazzale Roma (15–20 minutes).
- A private car or minivan takes you directly to the airport departure door (15–20 minutes).
Total time: 40–50 minutes. Total cost: €140–€200 (≈ $153–$218 USD) for up to 6 passengers, depending on the provider and vehicle type.
When to Book a Private Transfer
- Families with young children (car seats can be provided).
- Travelers with mobility issues who cannot manage steps or crowded boats.
- Early morning departures (before 5 AM) when Alilaguna and buses are not running.
- Executives or VIPs who value a seamless, door-to-door experience.
Pros & Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Complete door-to-door service | Most expensive option |
| Great for groups splitting the cost | Requires advance booking (24+ hours recommended) |
| No carrying luggage up/down stairs | Water + road transfer can feel less direct than a single water taxi |
| Available 24/7 with pre-booking | Limited availability during major events (e.g., Venice Biennale, Carnival) |
Verdict: A private transfer is the ultimate convenience for those who can afford it. Book through reputable platforms like Welcome Pickups or GetYourGuide Transfers for fixed pricing and vetted drivers.

6. Traveler Tips & Insider Advice for a Smooth Journey
After years of navigating Venice’s waterways, here are our top insider tips to make your trip from Castello to Marco Polo Airport as smooth as possible.
💡 1. Allow Extra Time for High Water (Acqua Alta)
Venice experiences periodic high-water events (especially October–February) that can delay water buses and taxis. If flooding is forecast, add 30–45 minutes to your planned journey. Check the Centro Maree website for real-time tide forecasts before you leave.
💡 2. Use the Luggage Forwarding Service (Takkyubin-style)
If you have heavy suitcases, consider using Venice Luggage Delivery or Baggage Storage Venice to have your bags sent directly to the airport. The cost is around €15–€25 per bag (≈ $16–$27 USD), and you’ll be free to enjoy your last morning in Castello hands-free. Services like LuggageHero and Stasher partner with local shops for drop-off.
💡 3. Book Alilaguna Tickets Online in Peak Season
From May to September, ticket queues at Arsenale and San Zaccaria can be 20–30 minutes long. Save time by purchasing a digital ticket on the Alilaguna app or via alilaguna.it before you arrive at the stop.
💡 4. The “San Zaccaria” Shortcut
If you are staying in eastern Castello (near Via Garibaldi or the Biennale gardens), it may be faster to walk to San Zaccaria (20–25 minutes along the waterfront) and catch the Alilaguna Red Line instead of waiting for the Blue Line at Arsenale. The Red Line runs slightly more frequently and reaches the airport in 55–60 minutes.
💡 5. Avoid the 7:30–9:00 AM Rush on Vaporettos
If you are taking the budget vaporetto + bus route, avoid the morning commuter rush (7:30–9:00 AM) when vaporettos are packed with locals and students. During this window, the Alilaguna water bus is often less crowded because of its higher fare.
💡 6. Check Your Terminal – Marco Polo Has Only One Passenger Terminal
Unlike some major airports, Marco Polo Airport (VCE) has a single passenger terminal divided into two piers (Domestic/International). All transport options (water bus, taxi, private transfer) drop you at the same terminal entrance, so there is no risk of going to the wrong terminal.
💡 7. Keep Small Change for Bus Tickets
If you take the ATVO or ACTV bus from Piazzale Roma, note that some bus ticket machines do not accept large bills (€50, €100). Carry €5, €10, and €20 notes or use a contactless credit card to purchase tickets directly at the machine.
Pro Tip: Download the Venice Airport App for real-time flight info, transport updates, and queue times at security. It can help you decide exactly when to leave Castello.

Travel time ranges from 30 minutes (water taxi) to 70–80 minutes (Alilaguna water bus). The vaporetto + bus combo takes about 50–65 minutes, depending on walking speed and waiting times. Add 20–30 minutes for check-in and security at the airport.
4. What is the cheapest way to get from Castello to the airport?
The cheapest option is to take vaporetto line 2 or 4.2 from Castello (e.g., San Zaccaria or Arsenale) to Piazzale Roma (€7.50) and then board ACTV bus 5 to the airport (€6). Total cost: €13.50 (≈ $15 USD) per person. The ATVO express bus is €8 but saves 5–10 minutes.
5. Is the Alilaguna water bus reliable for catching a flight?
Yes, Alilaguna is reliable for flight connections, but you should allow at least 90–120 minutes for the full journey from Castello to the airport terminal. Delays can occur due to weather, high water (acqua alta), or mechanical issues, so always add a buffer of 30–45 minutes, especially during winter.
6. Can I use a regular ACTV vaporetto ticket to go to the airport?
No, a regular ACTV vaporetto ticket (€7.50) is valid only on the ACTV network and does not cover the Alilaguna water bus or the airport bus. You need a separate ticket for Alilaguna (€15) or an ATVO/ACTV airport bus ticket (€6–€8). The ACTV vaporetto ticket can only get you as far as Piazzale Roma.
7. What is the best way from Castello to the airport with heavy luggage?
For heavy luggage, the water taxi (€100–€130) is the easiest and most comfortable option, as it offers direct pier-to-terminal service with assistance. Alilaguna water buses have dedicated luggage racks, but you may need to carry bags up and down stairs at stops. If your luggage is very heavy, also consider the private transfer or a luggage forwarding service.
8. How early should I leave Castello to catch a flight from Marco Polo Airport?
For a flight departing from Marco Polo Airport, leave Castello at least 3 hours before departure if using public transport (Alilaguna or vaporetto + bus), and at least 2 hours before if taking a water taxi. This accounts for travel time, check-in, security, and potential delays. During peak season (July–August) or major events (Carnival, Biennale), add an extra 30 minutes.
