Rochestown Woods - coming along the south ring from the aiport side, take the exit for Carrigaline, then take the first exit off, turn left at the bottom, and first right, up the hill, and the entrance to Rochestown woods is more or less straight in front of you. Pretty much beside the Garryduff Sports Centre. And close to Douglas. It's a bit of a walk in to reach the woods themselves but nice walking in there.
- Ballincollig Regional park,
- Rostellan Woods over Cloyne direction,
- Currabinny near Ringaskiddy,
- Marlogue Woods over Cobh direction,
- Farran Forest Park,
- little bit out of Cork over near Crookstown on the Killarney rd - Warrenscourt Woods.
- Ballinora Woods off Curraheen rd out the Ballincollig road but I think this is now private, sold by Coillte and not too dog friendly maybe, not sure.
-Moanbaun Woods at Watergrasshill.
- if it's a weekend and you feel like something different and a bit further, then you've got Garretstown Woods at Ballinspittle, Courtmacsherry woods (this goes out along the headland by the coast - fab walk), Castlefreke woods.
And then plenty more out the east side of cork. Obviously depends if you have transport! Have a look at the orienteering ireland website for events in Cork and you'll find a long list of woods!
Not much of a clue about within the city itself apart from along the river to Blackrock.
