The Lugar Sill
Where the Glenmuir Water Water joins the Bellow Water the river passes through a Site of Special Scientific Interest (SSSI) called The Lugar Sill. The Lugar Sill is a geological feature which has been closely studied over many years. One of the many igneous rocks found in the sill is Lugarite, an extremely rare rock found only at this locality.

The Glenmuir Viaduct
A short distance upstream from the confluence with the Bellow Water the Glenmuir Water flows underneath the Glenmuir Viaduct. This is a now disused railway viaduct closed in 1964 which carried the Ayr to Muirkirk line. The viaduct is B listed.
