Glanmire is a suburb that stopped pretending to be a village about thirty years ago. It's on the N25 — the Cork–Waterford road — which means it's an easy run into the city. Schools, supermarkets, housing estates. Families. The old village centre was absorbed into the housing sprawl sometime in the nineties. You can still find references to it on old maps, but the actual village of Glanmire is now a memory.
What you can find: a river valley. The Glashaboy River runs through here, a ribbon of green in the residential grid. There's FOTA Wildlife Park ten minutes west (via Carrigtwohill) — not a detour, more of a logical next stop if you're around. The rest is honestly what it says on the tin. You don't come to Glanmire for character. You live here if you work in Cork and want a quieter address. That's a perfectly sensible thing to do.
The reason to come back. The things every local will eventually tell you about, usually after the second pint.
On the N25 from Cork City Centre — ten minutes east. Carrigtwohill is two minutes further on the same road.
Several Cork Bus routes pass through. If you're using the city buses, ask the driver if your destination is on the route. They will know.
