Step 3: Buy a vaporetto tourist travel card or a supply of "disabled tickets."
ACTV, the Venice transportation authority, offers one- to seven-day tourist travel cards that allow unlimited travel on any of the city's water buses. You can buy these at the ACTV office in the Piazzale Roma or the vaporetto ticket booths near the railway station, the Fondamenta Nuove, the Piazza San Marco, and other locations.
Another (and more expensive) option may be the Venezia Unica tourist pass, which offers an a la carte package of vaporetto transportation, public toilets, admission to municipal museums, optional roundtrip transportation on the Alilaguna airport boat, and other perks with a frustratingly complicated pricing scheme.
Finally, passengers with wheelchairs can buy single-fare "disabled tickets" at heavily-discounted rates from ACTV ticket booths and Hellovenezia offices. Each ticket is valid for 75 minutes, and a companion travels free.
Once you have a pass or a supply of tickets, you'll be able to get between the city's various "accessibility zones" on the map by using the water buses. (The city claims that about 70 per cent of the streets in the historic center are accessible by vaporetto.)
This strategy works especially well on the Grand Canal, the Giudecca Canal, and the Lido, where the No. 1 and No. 2 routes are wheelchair-accessible.
The No. 1 boat is the most useful, since it zigzags from one side of the Grand Canal to the other on its 20-stop journey from the Piazzale Roma to the Lido. As the photo shows, this water bus can be crowded during the tourist season, but the conductor will usually clear a path for you, and the crew will help you on or off the boat quickly and without fuss.
Step 4: When in doubt, call ahead.
Most churches are accessible once you get inside. The tricky part may be in getting up the steps, but this can be managed if you have a strong companion or aren't shy about bumming a lift from athletic tourists or locals.
Other buildings, such as museums, may vary in accessibility. The most impressive rooms in the Scuola Grande di San Rocco, for example, require climbing a long flight of marble stairs--unless you use the special wheelchair with motorized rubber treads, which lets you assault the staircase like an army tank. Your best bet is to phone before you go, so you can make other plans if the building requires a sturdy set of lungs and legs.
More online information:
First, see page 3 of this article for a mini-map that shows wheelchair-accessible routes in the city center.
If you're looking for a place to stay, see our Accessible Venice Hotels article, which lists wheelchair-friendly hotels near the Piazza San Marco, on the Grand Canal, and by the Piazzale Roma (Venice's terminus for airport buses, taxis, cars, and the People Mover to the Marittima cruise piers).
The City of Venice has accessible Venice pages with general advice, an accessibility map in PDF format, a selection of barrier-free itineraries that are mostly up to date, lists of businesses that rent wheelchairs and accessible motorboats, and other useful information. You can also pick up a printed Accessible Venice kit in Venice or Mestre.
Another handy resource is the Venice page of Accessible Europe (see below), which--among other things--tells where to find accessible WCs and parking.
Be sure to read Dr. Monika Kuhn's illustrated Venice With Wheelchair & Handbike (PDF), which is available in English, German, and Italian. (It covers topics such as the accessible Hotel Monaco & Grand Canal, using water buses, crossing bridges, the tourist office's accessible walking itineraries, the best time of day to avoid crowds, sightseeing, toilets, and restaurants.)
Please note that information in guidebooks or on Web sites isn't always up to date. (For example, many guidebooks and sites still mention bridge lifts that are no longer in service.)
A guide service:
Mike and Karen Henderson of The Venice Experience offer guided sightseeing tours, including itineraries for mobility-impaired travelers.
Two agencies that specialize in accessible travel:
