Muirtown Basin is a large port area on the Caledonian Canal just above the first (sea) Lock where the Caledonian Canal meets the Beauly Firth.

This area houses a small marina and is popular for waterspouts with local sea scouts being based nearby.

The Caledonian Canal begins at Clachnaharry, connecting to the Beauly Firth via a sea lock. The Far North Railway Line also passes through, crossing the canal on a swing bridge. Clachnaharry used to have a railway station. This station opened in 1869 on the Inverness and Ross-shire Railway, and was the first stop after leaving Inverness, but closed in 1913.
