...both anchorages and moorings together but it is hard to tell what is what...
The info post above sounds appropriate, though assuming that you've an anchor
aboard, does it really matter? Even if you're intending to pick-up moorings the whole way, you will still need, to consider what you'll do if you arrive somewhere to find all the moorings are taken. If your enquiry arises from the lack of suitable ground tackle and/or the knowledge to use it, then for your own safety
(and that of the rest of us) I suggest that you perhaps address the shortcoming before setting off.
