It's also possible to come by public transport.  High-speed trains (TGV) run from Paris Montparnasse to Angoulême where there's a connecting bus and taxi service right to La Tour Blanche.  The bus and taxi journey is generously subsidized and costs only 2€, but you will need to book the train well in advance.  See this page for timetables:
