This was a very enjayable walk. We started in the carpark which has an information board titled "Eagles rock".

However, after meeting a local farmer he informed us that this information was misleading, and that eagles rock is not the impressive structure in the photo below (let's call it eagles rock 1):

But is actually the following smaller rock, seen on the left in the below image (lets call it eagles rock 2):

From the carpak, a path leads up to this smaller rock structure. The man advised us that we could park in the carpark and take the path up this this smaller rock without any trouble. We said we might consider continuing on to summit Tievebaun and/or Truskmore from there also, and to this the man advised that it would be safe to do this also and there is a way up. We were told that cars had their windows smashed in this carpark, but thankfully I drive an old banger so I wasn't very worried about this.
We found the track up to eagles rock 2 was very good, and would be suitable for young families. It gets very muddy just before you get to the rock, and you'll need to fence hop a bit to get into the rock itself and climb it.
We continued on and found a useful path with switchbacks al the way up to almost 350 metres. This made ascending easy enough, but when you get to the 400m line, I would advise you not to take the route I took in this GPS, but to instead bear more to your left to find a more managable elevation profile. I ended up scrambling and climbing a bit from 400m onwards and some sections were a bit dangerous if you are not used to scrambling in heather and brush. We also had a good bit of snow to contend with so this added to the risk factor.
Views from the top were magnificent, with Slieve league in the distance, as well as the bluestack mountains topped with an icing of snow. The local mountains like keeloges, aroo and aghalateeve all looked magnificent on this sunny day in February, as well as glenade valley and lough. This is a very accessible, short but highly rewarding hike indeed.
