To see each "wing" of the butterfly, you'll need to budget at least one day. They are connected by a bridge, and Grande-Terre has pretty villages along its south coast and the spectacular Pointe des Châteaux. You can see the main sights in Pointe-à-Pitre in a half day. Touring the rugged, mountainous Basse-Terre is a challenge. If time is a problem, head straight to the west coast; you could easily spend a day traveling its length, stopping for sightseeing, lunch, and a swim. You can make day trips to the islands, but an overnight or more works best. Leave your heavy luggage in the baggage room of your "mainland" hotel and take a small bag on the ferry.
