There are a couple of interesting land-based tours of Ottawa, including the staple Gray Line, but also two local contenders using more interesting vehicles: a Double Decker and the Trolley Tours which cover 20 major attractions and offer a hop-off-hop-on convenience (613-749-3666).
Take a tour along the Ottawa River, below the Parliament Buildings on the Sea Prince II, which leaves from the Hull Marina at the foot of Jacques Cartier Park in Hull.
