Best season to travel from London to Ottawa
Canada offers endless possibilities, from its rich gastronomy to its diverse culture and stunning nature. The best time to travel depends on your preferences and availability. Always consider the climate, peak tourist season, and the type of experience you’re seeking.
Expect larger crowds during peak season, but you'll also enjoy a lively atmosphere and more cultural and touristic offerings. Travelling off-season usually means fewer crowds, lower prices on flights and accommodations, and a more authentic glimpse into local life. While some outdoor activities may be limited due to the weather conditions, popular attractions will likely be less crowded, allowing for a more immersive experience.
