I have to agree with regard to walking around Arillas at night. Initially I did have my concerns those first few years, but this is something I most probably took over with me. Never would I walk anywhere at night in England. For my first visits someone usually walked me home from say the Coconut late at night. This year I walked down to the beach and the end of the pier as late as 2 or 3 in the morning, not on my own though, and did see many people, of both sexes, having a solitary safe walk.
