An ideal destination for a bike tour through Toronto. It's so wonderfully different than anything else you'll find in the city. Since Casa Loma is not centrally located, you will discover enough other sights during the tour.

Visit Casa Loma and step back in time to a period of European elegance and splendor. Completed in 1914, it took 300 men nearly three years to complete the almost 200,000 square foot castle at a cost of $3,500,000 (at the time). Situated on 5 acres, Casa Loma was once the largest private residence in Canada. Sir Henry Pellatt with his wife Lady Mary enjoyed Casa Loma for less than ten years before financial misfortune forced him to abandon his home. The 98 room castle, designed by architect EJ Lennox, features secret passageways, elaborately decorated rooms with authentic period furnishings, breathtaking views of the Toronto skyline from its towers and beautiful 5-acre estate gardens.
