A 20-or-so mile cycle route along the river Foyle. It takes you from Derry all the way to the border towns of Strabane and Lifford. Escape the traffic! You ride through quiet country roads and county lanes and get great views of the river and the surrounding countryside. Obviously you don't need a bicycle, you can just as well walk the distance if you prefer.
Don't forget your picnic :o)
Take this cruise to see Derry from the river Foyle. It sails down the river under the Foyle bridge (see pic) into Lough Foyle. Once it gets to Greencastle in Co Donegal it returns.
