For those who love pilotage and navigation challenges, the Channel Islands and nearby France is heaven (10/10), especially if your vessel can take the ground, since this allows many drying anchorages to be used. Within a day sail of most places there's a good choice of destinations in all directions; lively or quiet, French or English, marina or anchorage. Enough to keep you occupied for a good two weeks or more. But unless you're a fast vessel (over 10kts?) you must "go with the flow", and that often means rising in the early hours to catch the tides.
