An IMPORTANT NOTE on the Permanent Orienteering Courses at Ticknock: Some of the wooden control posts have been vandalised and removed. We are in contact with Coillte about replacing them, Currently (November 2016) we know that the following controls are missing:

Short course controls 1, 2;

Intermediate course controls 1,2, 10.

Advanced course controls 1, 6, 14.

Download Maps: The location of the downloadable maps has changed from the Coillte web site to the Dublin Mountains Partnership site.

For the Intermediate Course map click here;

For the Advanced Course map, click here.

If you find any more missing control points, please let us know at

Sorry for any disappointment or inconvenience. The orienteering clubs provide the map information and design the courses but course maintenance is the responsibility of Coillte/DMP.

November 2016 update: Coillte/Dublin Mountains Partnership are doing a review of the state of all the POC’s on Coillte property in the Dublin area.

April 2017 – Still no progress – the missing posts are still missing. We have contacted Coillte and the Dublin Mountains Partnership about it.

June 2018 – Coillte will be funding the survey of a new map of Three Rock and will be re-doing the permanent courses, so watch this space…

(Remember that we also have a Permanent O-course at Griffeen Park in Lucan and there’s one at the Phoenix Park Visitor Centre at Ashtown Castle, but you have to go there to get the map).
