Really pleased we booked this tour over the other companies. The boat is electric so makes no noise in the water, allowing us to hear the plentiful bird calls. Luis, our guide gave us all binoculars- a generous and lovely extra- and pointed out the different birds we all saw- osprey, egrets, heron, stork, tern, redshank, plover, curlew, kingfisher. The second half of our time was to enjoy the sunset and just being on the sea amongst the marshes. It was just magical. We dressed warm but blankets were offered too.
