The 2022 Brierley book says the Senda Litoral from Esposende is for experienced hikers as there is no way over the estuary at Foz de Neiva and no waymarks from Ponte de Neiva to PR13. My destination for this particular day of walking is Amorosa. I am wondering if the boardwalks are done. Or if I should follow the coastal route for part of the day before cutting over to Amorosa. And where to turn back to ocean? thanks.
