We have been visiting Scotland now twice annually almost every year since 2005. Our first visit to the Borders we were intrigued by this tall tower, and vowed to explore it on our next visit.
This we did, and enjoyed a picnic with stunning views from a bench in the field just below the Monument.
The following year, an offchance conversation with the potter at Smailholm Pottery, we learned that, Lothian Estates, in BonJedward, will hire the key for a nominal fee, and subject to signing a disclaimer.
So, the following year, we arranged to pick up the key, and I must say, are we glad we did! 236 steps later and you find yourself in a viewing platform atop the monument with the most stunning views! We took a picnic with us, and had a quite magical time.
I highly recommend you get the key, then park at the Harestaines Visitor Centre for about an hours pleasant walk up Penniel Heugh to the Waterloo Monument.
