Turn left from the Royal Inn and head down to walk over the absolutely stunning 14th century bridge across the Tamar. Stay on the lane after the bridge, pass a turn to the right for Bridge Farm and then just after the corner turn left through a wooden gate onto a signed path. It's exactly a mile to the next village of Luckett, and this is a there-and-back route so simply turn around when you're ready. There's a high chance of sheep in the fields close to Luckett, before that it seemed to be livestock-free and Jem was happily off-lead.
