COURSE INFO

CAMPING

The first campground you see when you enter the park is RV camping with full hookups, but that’s not where we are holding the race. Continue down the road and follow the signs for Farley Field/Trade Days. You’ll go over a wooden bridge and in front of you opens the vast expanse of Farley Field. This is our home for the weekend! (ALL RVs/CAMPERS TAKE LOWER ROAD. DO NOT CROSS THE METAL BRIDGE.)

Farley Field has water and electric for RV camping & there is a dump station within the park. There’s also a primitive camping option.

Camping is first-come first serve and no reservations are available. This is a PARK POLICY.

All racers staying overnight at Farley Field must register in the Temporary Campground Store (located in The Creamery.) No exceptions.

Full Hook-up Sites: $30 per night per family of four and $3 for each additional person.

Power and Water Sites: $25 per night for up to 4 people. $3 for each additional person.

Primitive camping is $20 per site up to four people. Primitive is no power or water.
