Same here! Walked down around 11 am and, apart from the harbour being closed to parking alongside the shops, there was nothing happening. We tried the beach and harbour but couldn't find anything that we could describe as a "special event". Our Councillor for Tourism made a tour of town on Friday proclaiming that "Los Gigantes is open on Saturday and Sunday", although I didn't catch what it was open for. Clearly, it wasn't for parking by the harbour!
