Octane Adventures operates ATV and snowmobile tours across three Central Oregon locations. Near Sisters, guided ATV tours depart from the McKenzie Pass trailhead in the Deschutes National Forest, offering the 2-hour High Cascades Scenic Tour through Cascade Mountain peaks and ancient lava fields, and the 4-hour Black Sands Tour featuring black volcanic sand dunes, alpine lakes, and 360-degree viewpoints. Self-guided options with brand-new Polaris RZR vehicles and pre-loaded GPS maps run 4 or 8 hours through the Santiam Pass trail system. On the Millican Plateau near Brasada Ranch, the 2-hour Hidden Canyon Tour winds through ancient juniper forests and high desert terrain with Crooked River canyon views, operating March through November. All ATV tours use automatic-transmission Polaris vehicles; no prior experience required. Winter snowmobile tours run December through April in the Newberry National Volcanic Monument near Sunriver, featuring Paulina and East Lakes and Newberry Volcano summit access when conditions allow.
