One keen walker said: "Lovely trail with a mix of fields, forest and the end is along the canal. Hardly any hills and the few that there are, aren’t steep.

"Think it’s listed as hard because it’s so long. We did this in 7 hours, including a 30-minute break and found it challenging in length but overall really enjoyable."

River Colne and Munden Estate Circular

Difficulty: Moderate

Rating: 3.6

Last but not least, this circular walk takes an average of 1 hour 49 minutes to complete its 5.6km length.
