Ottawa scavenger hunt: Parliament Hill, the Rideau locks and a giant spider
The Ottawa scavenger hunt is a self-guided city game you play on your phone: you walk from landmark to landmark, solve a riddle at each one by looking closely at what is in front of you, and unlock the stories and legends behind it. Between Parliament Hill and Nepean Point you walk only some 34 minutes, 2.4 km over 10 stops, which leaves most of the roughly 2 hours for riddles, stories and views over the Ottawa River, starting whenever you like.
Highlights include the Parliament of Canada and the Centennial Flame, the National War Memorial, the Famous Five monument, the hand-operated locks of the Rideau Canal, the silver spires of Notre-Dame and the giant spider outside the National Gallery. The route is short and stays close to the Ottawa River, with wide views from Parliament Hill, Major's Hill Park and Nepean Point.

Riddles from the Peace Tower to Nepean Point
Shields, an empty chair, an upside-down instrument
Every stop hides its answer in plain sight: the provincial and territorial shields around the Centennial Flame, the empty chair among the Famous Five, the astrolabe in Champlain's raised hand. Nobody on the team needs to know Canadian history; what counts is noticing details and thinking them through.
A fire, a canal and a court case
Solved riddles unlock Ottawa's stories: the fire of 1916 that destroyed the Centre Block but spared the Library of Parliament, Lieutenant-Colonel John By building the Rideau Canal between 1826 and 1832, and the five Alberta women who won the Persons Case in 1929. The stories can be read in the app or played aloud as audio.
2.4 km along the river bluffs
Google Maps leads you for about 34 minutes in total, from Parliament Hill down beside the locks and up through Major's Hill Park to Sussex Drive. There are a few slopes, and the reward is a run of views over the Ottawa River.
Breaks by the ByWard Market
Nothing is timed, so you can step off the route near Notre-Dame for a snack in the ByWard Market, sit in Major's Hill Park or carry on tomorrow. The app saves your place and opens the next riddle when you are back.

Who will enjoy solving Ottawa's riddles
An afternoon to spare in Canada's capital
In about 2 hours the game strings together Parliament, the canal, the cathedral and the National Gallery, a good first look at Ottawa before a museum or dinner. The riddles slow you down at details you would otherwise walk past.
Families with sharp-eyed kids
A giant bronze spider, a flame burning above a fountain, an empty chair to sit in and boats lifted by hand-operated locks give children plenty to find, with an adult in every team.
Friends, school classes and colleagues
Teams of up to 5 play side by side, each person on their own phone, so a larger group can leave Parliament Hill in waves and meet again at Champlain's lookout on Nepean Point.
