The walk starts in Largs where evidence of Roman baths were unearthed in 1820. The route follows the Ayrshire Coastal Path north via Pencil Point for a refreshing promenade along the seafront.
At Noddsdale Water the route heads inland, but still on the Ayrshire Coastal Path (!), and gently climbs until reaching the Iron Age hill fort on The Knock (known locally as Knock Hill) where, weather permitting, there should be good views.
The descent is down Blackhouse Burn, then passes close to Knock Castle before returning to the seafront and following the Ayrshire Coastal Path back to the Marina.
At around 10 miles it is a relatively easy walk but can be muddy in places!
