Guests will also enjoy tours of the park, artists creating works and much more.

Park goers can also take in the 250 sculptures that reside throughout the trails of the park, making it the largest outdoor sculpture park In the United States.

The events will take place on the top of the hill by the stage at the Mill Valley side of the park.
