Reservations - Guernsey


Guernsey State Park has 125 reservable campsites  (electric hookups and non-electric available), 4 yurts and 2 Day Use Shelters that may be reserved by contacting the SPHS&T Reservation Call Center at 877-996-7275 or booking online

Regular campsite reservations are accepted for arrival dates between May 1st - September 30th, 4 months in advance. Yurts may be reserved all year round, 4 months in advance. 

IMPORTANT SILT RUN INFORMATION! Please take into consideration the Guernsey Annual Silt Run when booking reservations. The reservoir at Guernsey State Park is subject to one (and occasionally two) silt runs each year as determined by the federal Bureau of Reclamation with often very little advance information. The first silt run typically occurs after the July 4th holiday but this may vary from year to year.

A silt run reduces the water level in the reservoir to a degree that water recreation activities are typically completely restricted. Any change and modification fees associated with reservations apply throughout the silt run.
