The beautiful landscape of the Rūmene Manor includes an English style park that was designed in 1890 by Georg Kuphaldt, the director of parks for the city of Riga and one of the most influential landscape architects of his time. Kuphaldt also designed the Arkādijas and Viesturdārzs parks in the Latvian capital. 

The vine-covered pergolas on the Italian Renaissance-style terrace that connects the manor house with the park provide a special background for celebrations and wedding ceremonies. The park also includes three unique glass sculptures by Latvian artist ernestO (Ernests Vītiņš).
