Getting to the beach is easy - it's well signposted from the town, and parking is plentiful. As you can see from the photo below, there are LOTS of stairs to get down to the beach, so take your time as some of them are quite steep.
The bay itself is stunning wth soft golden sand and huge towering cliffs which give you shelter from the wind, which can sometimes be quite strong in this part of the Algarve.
Out of season it can be really deserted, and even in the busy summer months, it would take a lot of people to make it busy! It's hard to sum up just how big this beach is, so take my advice and go and see it for yourself if you're in Portugal.
