Another local walk
Hulne Park is the Duke of Northumberland’s park surrounding Alnwick Castle. The park is open daily (at present between 11am and 4pm), entry is free. There are a number of routes signposted around the park and one particular favourite is the Brizlee Tower Loop where you come across a monk by a cave, a Tower on a hill, a grave site and a fantastic view over North Northumberland. This walk take about 3 hours and there are plenty of place to stop with your flask.
If you visit Northumberland Estates website you can download walks around the park and view the open times. Happy walking. http://www.northumberlandestates.co.uk/the-estate/walks-trails/
