Hoypus Forest is split into two main areas. To the north is Hoypus Point Natural Forest Area, one of the largest remaining old growth forests in Washington. Among the attractions is a portion of Cornet Bay Road that is now closed to vehicles with views of Cornet Bay and the Deception Pass Bridge. The road provides access to Hoypus Point, the old launch location of the Deception Pass Ferry (read more here). The CCC Crossing trail, which was once used by Civilian Conservation Corps members to haul lumber for park structures, meanders east to west through the forest. With the exception of Cornet Bay Road, no bikes or horses are allowed in this area.
To the south is Hoypus Hill, which features a mixture of forest types and ecosystems. The multi-use trails (horses and bikes allowed) run through mature forests, alder groves, and even around the perimeter of a bog. Among the highlights is Julie Trail, a steep connection between the Old Hoypus Hill Logging Road and Fern Gully through a swath of enormous sword ferns.
