Economically, Ghana is one of the most sucessful countries in West-Africa. It also has a lot to offer to visitors. on a relatively small area and since transport is good by African standards you will find travel enjoyable.
Your trip to Ghana will probably start in Accra, the capital. It is a vibrant city with some good museums and many colourful markets. It is an ideal starting place to explore the country since the distances are not too big and Accra is the travel hub of Ghana.
The coast towns of Ghana played an important role in the days of the slave trade and there are many forts that remind you of this period. The forts and the beaches are the prime attraction of this area. Elmina, Cape coast Shama and Dixcove - where you can sleep on the beach or in a fort - are among the hot spot on the coast.
In the centre of the country Kumasi has a huge market and great opportunities for buying art and handicrafts. Although the city is wonderful and abuzz, it can be disorienting, hot and crowded. The area around is perfect for daytripping.
The main sight in the north is probably Mole Game Reserve which is off the beaten track but worth your while.
