Olmstead Place State Park is a 217-acre day-use park that features a working pioneer farm. The park hosts tours and school field trips. Pioneer artifacts are plentiful in the park, and many can be seen in action in the work of maintaining the farm. Picnic space and walking trails interweave with interpretive activities.

This area is the location of one of the first homesteads in the Kittitas valley. The Olmstead family arrived in 1875 and lived on the farm for about 100 years before donating it to Washington State Parks in 1968. Today, it continues to be a working farm, with some of the land still worked with old-fashioned equipment. The original 1875 log cabin and 1908 farmhouse (with the family's furnishings intact) are still standing, as are most of the outbuildings.

A Discover Pass is required for vehicle access to Washington state parks for day use. For more information about the Discover Pass and exemptions, please visit the Discover Pass web page.

The park has no camping.
