We present Gemini- North GMOS/ IFU observations of a young star cluster and its environment near the centre of the dwarf irregular starburst galaxy NGC 1569. This forms part of a larger and ongoing study of the formation and collimation mechanisms of galactic winds, including three additional IFU pointings in NGC 1569 covering the base of the galactic wind which are analysed in a companion paper. The good spatial and spectral resolution of these GMOS/ IFU observations, covering 4740 - 6860 angstrom, allow us to probe the interactions between clusters and their environments on small scales. For cluster 10, we combine the GMOS spectrum with Hubble Space Telescope imaging to derive its properties. We find that it is composed of two very close components with ages of 5 - 7 Myr and <= 5 Myr, and a combined mass of 7 5 x 10(3)M circle dot. A strong red Wolf - Rayet emission feature confirms our young derived cluster ages.
