You can easily reach Ullensvang by car. If you come from the East it is good to drive over Haukelifjell or Hardangervidda. If you come from Bergen it is a good option to take a car ferry from Tørvikbygd to Jondal. From the South (e.g. Haugesund/Stavanger) it is a good option to use E134 and stop by Langfoss waterfall along the way, or drive the National Tourist Route Ryfylke.
In Ullensvang you will find two of Norway's National Tourist Routes, which makes this a beautiful area to explore by car. One of the tourist routes runs along RV13 between Kinsarvik and Låtefoss waterfall, and the other runs between Utne and Jondal. Both roads are beutiful all year around, and particularly beautiful during the fruit flowering season in Spring.
