http://www.localmotion.org/island_line_ bike_ferry . Round-trip tickets: adults, $8; ages 7-17, $5. Children under age 6 are free.
Season passes available. Until Labor Day, the bike ferry operates daily 10 a.m.-6 p.m. Between Labor Day and Columbus Day, it operates Friday, Saturday, Sunday and holidays.
TIPS: There are numerous places to park on both sides of the causeway. Local Motion rents bikes in downtown Burlington and free maps are readily available along the trail. For riders interested in the “triple ferry loop,’’ two of the ferry legs are on the separate Lake Champlain Ferries, which carry vehicles and passengers, http://ferries.com/.
