The Varadero Golf Course is a really enjoyable place to play and I have spent four separate one week vacations there over the past ten years. It is not going to appear on anyones "Best of " list but there are some really good holes, the best, to my mind, is the Par 3 8th, which sits on a cliff top overlooking the miles-long Varadero beach. Part of the course uses an old 9 hole layout owned at one time by the Dupont family.
There have been reports of further course development in Cuba for many, many years and sooner or later more development will be forthcoming, especially with the liberalization of land ownership over the past few months. But I wouldn't be planning on a Cuban golf tour anytime soon.
But Cuba is a beautiful country, the people are incredibly warm and friendly and the cigars and rum are (very) cheap!
