Yiannis,
A date the site was last visited may be useful. I’ve been to places in Greece and Austria many years ago that had dark skies but I wouldn’t vouch for them now.
Paul,
In the past I have offered to accommodate BAA members who happen to drop by my place in La Palma when I am also in residence. That offer is still open for the time being.
A generous offer. If that doesn’t boost BAA membership I don’t know what will!
