The theme park plans to enhance the "High Sierra mountains camp" area of Camp Snoopy for its 30th anniversary. New rides are also planned.
In addition, the Calico Mine Ride will be refurbished with state-of-the-art animatronic figures and enhanced scenery, the park said in a statement.
The Calico Mine Ride attraction stands seven stories tall and takes eight minutes to complete. The ride will close for its refurbishment in January.
Camp Snoopy and the Calico Mine ride are scheduled to open early next summer.
