We present results from a study of the seeing quality at the 4.2-m William Herschel telescope at La Palma. The median intrinsic seeing at the site is found to be excellent, and is comparable to that at the Paranal and Mauna Kea observatories. Contributions to the seeing from turbulence within the telescope dome are insignificant. Furthermore, the optical quality and tracking stability of the telescope are good, so that long-exposure image widths close to the limit imposed by the site seeing can be expected.
