You will find this tomb on the left as you travel down the curvey R480 from Ballyvaughan. It is not very well marked but all you need to do is watch out (literally, if you are speeding!) for the numerous cars and occasional buses that are park on and off the road near the entrance gate.
We visited during a quiet time when the weather was not at its best so there were not that many visitors but, even so, parking was difficult as the road is barely two cars wide and there is no actual allocated parking spaces.
Once you find the tomb, it will only take about 30-40 minutes to go and look at it, take a couple of pictures and then return to your car.
This megalithic burial tomb only lies a short distance from the road but to access it, you do have to follow a rough path over the limestone rocks and clefts of the Burren. There is no easier path than any other, as people take whichever route that they think is easy for them.
There are no viewing time restrictions to this site and it should be free (it was when we went). However, I am told that when the majority of the tourists arrive with the summer, so do a couple of local farmers touting a bucket or two, to see if they can get an entrance fee to the area. Fair play to them, we all have to make a living, one way or another!
The tomb was excavated in 1986 and the remains of 33 people were dsicovered, some dating back to 3800 B.C.
This site dated back to about 2500 BC! Dolmens were used as graves back then and there are several existing in Ireland still. With its 10 ton stone on top of it Poulabrone is one of the most impressive of these!
