Is right on your doorstep if you are in the Algarve and if you landed at Faro then you flew over it!  I am talking of course about the beautiful Ria Formosa.

As regular readers to this blog will know one of the reasons we return again and again to the Ria Formosa is the birdlife. As well as being one of the stop-over points in the bird migration routes it is also a wintering ground for birds, particularly waders, DSCN8288from northern and central Europe. There can be around 20,000 birds here during the Winter months.  Don’t worry though if birds are not your thing as there are plenty of opportunities for boat trips, walks and cycle rides, and of course there are also the glorious beaches, which even in the height of summer apparently have quiet(ish!) areas.

DSCN8134For those who have not visited before, the Ria Formosa is a large lagoon on Portugal’s Algarve coastline, extending around 60km east from Faro to a few km west of Vila Real de Santo Antonio. The lagoon becomes a labyrinth during falling and low tides as hundreds of sandbanks and channels appear.  At times it can feel as though there are islands everywhere, there are in fact only 5 islands which create a barrier to the Atlantic.  There are 6 inlets from the Atlantic but only one permanent river – the other rivers I understand from this environmental report dry up in the Summer – so consequently it is a coastal water lagoon.  Today I thought I’d a share a little bit more about the Ria Formosa tides.

DSCN8937The tides are part of life here in the Algarve, and a few hours ether side of low tide you will notice local people heading out onto the sands to dig for clams and other shellfish. Some head out by walking (or wading!) from the saltpans or the small beach by the marina, others heading out in small boats to the sandbanks further out. Just occasionally one of them leaves it rather late to return and you will spot them in the channel with the water up to their chests and their basket on their head.

In the past the power of the tides was utlized through tidal mills.

Today though there are no working mills left as far as we are aware, but one has been partly restored at the park’s headquarters on the outskirts of Olhão and ruins of others are dotted throughout the area.

DSCN1174Whilst we have explored the Ria Formosa from the islands a few times now, and explored it further east most of our strolls tend to be in Olhão’s saltpans.  It is around here I have begun to try and to capture the range of the tides.  The tides are 6hrly so most days there are two high and two low tides.  The tidal range (between high and low) is from 1.5m to 3m, but is the variation in height of the high tides which has enthralled us.  The highest tide we’ve seen was at least 3.7metres  – can’t be definite on height as it was windy that day so may have been higher.  A few days earlier the high tide was only 2.7metres.  Below are a few shots of the same channel at different high tides.

Occasionally this is high tide

Occasionally though this is as high as high tide gets

Watching the tide come in and go out is a lovely way to spend a few hours.

So if you have not yet been to this Seventh Wonder then make sure you do soon, and if you are wondering about the other six Natural Wonders.  Two are in the Azores, one is Madeira and the remaining three you have the caves of Mira D’Aire near Fátima, Portinho da Arrábida about 40 km south of Lisbon and Peneda-Gêres National Park in the north.  I’ve only achieved 2 of the 7 so have lots to do on our return trip this Autumn!
