Waterlines is a heritage centre and museum, sharing information on the local history, geology and wildlife of Lybster.
The museum cafe has a reputation for its fresh crab rolls and serves savoury dishes, cakes, ice cream and hot drinks.
On a pleasant day, you can sit outside the cafe, overlooking the harbour and lighthouse.
A small number of crab fishing boats still operate from Lybster harbour.
Caithness Seacoast boat tours run a 3.5-hour trip from Wick to Lybster with time to visit Waterlines Museum and the harbour as part of the tour.
