Old Mill and Grand Union Canal Walk

Route Description for Old Mill and Grand Union Canal Walk

Most walkers leave The Old Mill and Grand Union Canal Walk without encountering any hindrances. However, despite the surrounding beauty, adorned by the canal, you will spend a lot of time walking with the main road within earshot. Yet, the beauty unfolding in front of you should help distract you from the rumblings of nearby traffic. You will also have to cross the A4251 a couple of times, requiring you to be mindful of cars and to think twice about bringing younger children along. Lastly, you’ll have to navigate a kissing gate and steps leading to the canal.

The gentle undulations paired with winding next to a canal make this walk a charming choice for anyone looking to move around outside without forcing their body to work too hard. Plus, you can look forward to a rewarding pint at The Old Mill afterwards!
