One of the few pure stands of oak trees in Latvia, this one covers 19.6 ha, and it was declared to be a protected territory back in 1928. The oldest trees are 300 to 400 years old. The stand of trees can be found alongside the Ezernieki-Andzeļi road. There is a small car park, along with a hiking trail, an information stand, and a leisure area with a plank from which the northern bay and islands of Lake Ežezers can be seen very well. There are typical species of plants, mushrooms and insects here, but only a specialist will be able to recognise them.
