The buildings of the Dikļi castle are organically complemented by a park spanning 20 hectares. Adjacent to the palace lies a duck pond, which is said to have had a floor made of oak. Mazbriede River begins just beyond the pond, whose ravines contain a landscape garden, also known as the Forest Park. In the 1960s, after surveying Dikļi castle park, it was found that approximately 20 exotic trees grow on its grounds.
Dikļi castle is one of the few palaces and landed estates in Vidzemes where much of the original interior décor has been relatively well-preserved. The palace contains a collection of luxurious old stoves and fireplaces. Dikļi castle was restored in 2003. At the moment, the palace houses a hotel, a restaurant, a spa and it provides a venue for various functions.
