Abernethy Castle Law (2.4 miles)
Start at the round tower in the middle of the village. It dates from the 11th century and is one of only two surviving examples in Scotland of this type of structure. Further down School Wynd is the excellent Abernethy Museum, open Wednesday to Sunday during the summer months from 1pm to 4pm. Back on Main Street, turn right and walk 350 yards to the end of the road. You will pass The Inn which offers real ale.
Just before the roundabout take the path to the left signed for Castlelaw. This heads steeply up the glen before meeting a single-track road. Turn left and climb for 130 yards. A track leads off to the right which switches back a couple of times en route to the summit. A couple of benches are provided along the way and sweeping views of the Tay Valley can be enjoyed. You can see all the way to the Tay Bridge and Perth. The River Earn empties into the Tay and if you're lucky you might even see a train crawl along the valley floor.
Retrace your steps to Abernethy. Berryfields Tearoom is opposite the tower and serves an excellent range of food and drinks. You can also request the tower key for a climb to the top. Another recommended outing is the Lindores Abbey Distillery three and a half miles along the road in Newburgh, Fife.
