Binsar was the summer capital of the Chand Kings, who ruled over Kumaon from the 11th to 18th centuries AD. Binsar was established in 1988 for the conservation and protection of the shrinking broad leaf oak (Quercus) forests of the Central Himalayan region, and it has over 200 bird species. It has a museum about the flora and fauna of the region. The sanctuary hosts 25 types of trees, 24 types of bushes and 7 varieties of grasses. The higher altitudes are covered with oak and rhododendron trees. In March and April, flowers, especially ruby red rhododendron, are in full bloom.
