Tumalo State Park was established in 1954. It is located approximately northwest of Bend. The park preserved a scenic portion of the Deschutes River where basalt cliffs extend down to the river. It also created a day-use picnic area and a public campground.
The original were given to the State of Oregon by Deschutes County. Minor property adjustments have been made over the years. In 1959, the state returned to the county for a roadright of way across the southern part of park. The road connected residents living south of the park with the old highway. In 1960, the state purchased an additional. A year later, the state granted another road easement to the county, allowing Johnson Road to cross the western corner of the park. This reduced the park's area by. In 1963, a third road right of way reduced it by another. In 1972, the county gave an additional to the state to expand the park. Additional land purchases and exchanges over the next decade brought the total park property to.
Topography
Tumalo State Park is located in the Deschutes River canyon, running along both sides of the river. The park land on the east side of the river is mostly level with a gentle upward slope toward the east. The slope becomes much steeper at the eastern edge of the park. On the west side of the river, the park land is for the most part level.
The park is bisected north to south by O.B. Riley Road which is a rural highway running from the city of Bend to the unincorporated community of Tumalo. The developed part of the park is on the south side of the Deschutes River. Park facilities include access roads, parking areas, manicured lawns, restrooms, solar showers, laundry facilities, public phones, hiking trails, a large picnic area, and an overnight campground. The picnic area is west of the highway, while all the campsites are on the east side of the highway. In the picnic area, there is a group shelter that can accommodate 50 people. The campground has 50 tent sites, 23 trailer hook-up spots, and seven yurts. The park is open year-round. In 2013, the Oregon Parks and Recreation Department reported that Tumalo State Park had over 263,000 day-use visitors and more than 49,000 overnight campers per year. Tumalo State Park is a very popular site for wading, swimming, and inner tubing during the summer. There is also a children’s playground available for day-use visitors. The park provides access to several hiking trails that are also well used by mountain bikers. Fishing along the Deschutes River is very good, especially in the spring and late summer. Rainbow and brown trout are the most common catch. In addition, the juniper woodlands, riparian environment and rock cliffs along the river attract a wide range of birds, making the park a good place for birdwatching.
