We visited Aira Force when on holiday in the Lake District in mid May 2013. We drove from Ambleside through to Windermere and then on to Aira Force.
Like a lot of the roads around the Lake District there are some tight spots on this road. If you have an older car with various scratches on it already you won't mind. If you have a new car it might be a little more stressful, at points. Some of the other car drivers seem to want to take up part of your side of the road to avoid damaging your car. Unfortunately there are a lot of dry stone dykes and untrimmed bushes right at the side of the road. However, that is a Lake District thing not specific to the trip to Aira Force.
The drive has a good number of points where you will want to decant the car and take a look, or a photo.
There is a car park beside Aira Force but it is not Free. Remember to take long a number of £ coins (at least 4). We went when the small team room was closed and had to pop sway to get some more change as we did not have enough.
Once you are parked there is a nice walk to both the bottom and the top of the falls. some of this is reasonably steep and there are quite a few steps so those with mobility issues may want to think carefully about this one.
The walk is nice and the view of the falls from the bottom and top is picture worthy. They are not the biggest falls but they are worth a visit.
After having a good walk around the area of the falls don't forget when going back to the car park to take a walk across the road and down the track, into the field and down to the lake side. More good views and photo opportunities to be had there, on a good day.
There is a car park/layby located above the falls. It did not appear to be one that had a ticket machine so possibly another option if you find you don't have any change on you.
Overall I thought the falls were worth a visit, but not spectacular. There are a number of good photo opportunities on the journey to the falls, around the falls and the falls themselves.
Would I go again, yes probably.
