Beacon Hill is located right next to the A34 and is easy to find. It's a tough climb to reach the 261 metre peak, but the view is worth the effort.
There are several interesting things to see. When you reach the top, look back the way you've come, across the main road. In the distance, you can see Watership Down, the real place that inspired the novel by Richard Adams. Adams lived nearby in Whitchurch for most of his life, and all of the locations in the book are real places in the area.
Watership Down is the hill in front of the TV mast
Turn back towards the hilltop and you'll see a deep ditch in front of you. There was an Iron Age hillfort here around 3000 years ago, and you can still see the defences that were dug around the camp. Apparently, there were at least 2000 people living up here.
From the right-hand side of the hill, you'll see a large country house down below. This is Highclere Castle, where Downton Abbey was filmed. It's possible to take a tour of many of the rooms that were seen in the TV show, although you normally have to book well in advance.

On the far side of the hill, you'll find a grave surrounded by a fence. This is the resting place of Highclere's most famous resident, the fifth Earl of Carnarvon. Lord Carnarvon sponsored the expedition that found Tutankhamen's tomb, and he was with Howard Carter in 1922 when the treasure chamber was opened for the first time.
