At the end of the peninsula south of Tayvallich lies the little-used Keills Port. This slipway is the still-operational South Quay and maintained by Argyll and Bute Council. The gated road to the quay is a public road its full length and, contrary to the signs, it is possible to turn a vehicle at the quay end. That said, the best approach is on foot or bicycle to maintain the tranquility of the place. This was once busy with traffic from the Isle of Jura, which lies across the sound. Seals and otters can be seen here and the slipway itself is covered with sea pinks in the spring.
The quay was built in 1821 on the orders of the Parliamentary Commissioners for Highland Roads and Bridges and is attributed to Thomas Telford.
