Laxey Glen is easy to find and a very nice walk, especially with kids. To access the Glen just pull into the carpark by the bridge at the Flour Mill in laxey and either follow the road left (to park at the bottom of the glen), or right and park at the top if you want a bite at the cafe.
There’s quite a lot to do in this glen, aside from the actual walk there is the cafe and a kids play park as well. There are also various tracks up through the forest in the glen but I prefer to just stay by the river.
If you are are really looking to stretch your legs, follow the rack up as far as the foot bridge and then cross it and follow the track up the hill. It is steep, but comes out on a road that takes you back down to Laxey village.
