Hi Dawn
There are 2 lovely quiet coves that are accessable by boat or foot.
If you travel up to Afionas there is a gift shop, walk down the side of this shop and if you look carefully there is a small track, it's quite a walk dwn the side of the cliffs but well worth it. You can also hire a boat from St George and it would only take you 5 minutes to peddle there. The sea is an unbelievable colour and it's so peaceful.
As Carol said even the main beach is looking desserted, when we were there a week ago there was only a handful of people on it.
I'm sure you'l have a great time, let me know if you find the coves.
Best wishes Jill
