hiking at sunrise

from cds.me

I cannot remember when you are walking, so its a bit hard to tell you when dawn and dusk might be. Remember, though, that Spain is unusual inasmuch as it is at the same longitude as Britain, but on a western European time zone. So dawn about an hour or so later than you might expect if the country were using a time zone more aligned to its geography.

You might also want to understand the differences between the various twilights. It is generally possible to walk in reasonable safety without a torch from the start of civil twilight, or about half an hour before sunrise and after sunset if you are in the open. It is more difficult if you are walking in woods or forests where it will still be too dark to walk until closer to sunrise. Wikipedia has a good description of the differences. I have walked from nautical twilight, but more care is needed if you don’t use a torch or headlamp.
