The five add up to the 100-point Powder Score: more fresh snow, more on the way and colder air all push it up. How we measure
Most of Tambara is beginner and intermediate terrain, and the Family course averages a gradient of just five degrees. In summer the same Tambara plateau opens as a lavender park, so the highland trades gentle ski runs in winter for fields of lavender in summer.
