The Barn is located on the far side of Marahau towards the Abel Tasman Park. Keep following the main road through the beginning of Marahau. You will reach a bridge across the Marahau river. From there you will see the the Abel Tasman foothills and The Barn is about 250 m further on, just past the Park Café (great meals and evening bar)!
We are about 25 minutes drive from Motueka, around an hour from Nelson and around 3 hours from Picton.
