Now this is a bit of a strenuous one, but the views you are rewarded with are amazing..
Main Road between Peel and Douglas, at Greeba Castle you will see a place to park on the bend. Leave your car there and start walking toward Douglas until you see the Footpath leading you into the King’s Forest. Then learn to love walking up hills!
It is a pleasant walk, and there is an easy way, and a hard way (such as life!), the hard way you will see about 10 minutes into the walk, and it is kinda the ‘straight way up the hill’. Just follow the path next to the old shack that goes up, simple really. This is like walking up stairs in places, so isn’t for everyone. The other way is to just keep on the wider trail and that zig zags through the forest and meets the other track towards to top.
When you get to the top of forest continue over the stile, and follow the path to the top of Greeba Hill.
Whichever way you go, this is a rewarding walk. Make sure you have suitable footwear and plenty of liquids with you. This may not be one for little legs in my opinion, but maybe give it a go yourself and see how you get on.
