Keiss harbour was built in 1832 and is still used by local fishing boats for crab and lobster fishing in Sinclairs Bay. The harbour was built using local stone and old harbour warehouse is now a luxury holiday home. The nearby fishing buildings are now listed buildings, part of Scotland's fishing heritage. The nearby Keiss beach provides miles of lovely sandy beach with views over to Noss Head Lighthouse.
Keiss harbour is tidal and this restricts access to the harbour at low tide. The local boats in the harbour include leisure boats used for sea fishing in Sinclairs Bay and small fishing boats mostly used to crab and lobster fishing.
