Doesn't seem there's a RED gate as the website suggests. (Updated listing website link from 404 error present link gives.) Turn off Havana to E. Broadway & drive along - enter at a fairly set back Gate G at the end of the old barns on East side of grandstand. Arrived after 10pm, gate was closed but not locked. Power & water were easily available by well-marked posts. Was pretty much empty, so pick of grass site spots. Made our own pull-through as we were towing a bike trailer. Toilet facilities are older but clean & functional. Trains…horns bells & engine noise-yes, industrial truck beeping, yes, but not horrible. Have not paid yet, not sure where office is! LOL! Will seek it out on exit. Would stay again. My parents were here last November '16 and also liked it & would return.
Good for a night or two, water & electric only. If you arrive after 4:30 the office is closed and no apparent way to pay. Hard to locate, enter off Broadway near the stables. The park is well off the street and hard to see. No facilities but large spread out spaces with good satellite reception. Nothing fancy (at all) but a good landing spot and close to shopping and Flying J.
The entrance is off Broadway on the east side of the grandstand.
Confirmed access IS Gate "R" and the sign was RED, but it's not really visible from the road at night. Paid for the night stay at the County Fair office - there are several buildings in the main parking lot: Seattle Indians baseball, nope, Parks & rec, nope. Drive as far straight in to the parking lot and to the left is the Fairgrounds office. They accept cash or credit. Price $26 if you use water & electric, but… you didn't have to hook up.
It took us a while to find where the RV parking was - the fair grounds were totally vacant and there was no directional signage. Once we spied a couple RVs parked, we pulled in (at maybe 6pm). There was no attendant, but we parked and hooked up anyway (no obvious payment instructions either). There were 2 others camping - very quiet and strange feeling. Right next to train tracks, but didn't hear any while we were there. No playground or anything for the kids, but it was just an overnight stop, so whatever. And since there was nowhere and no one to pay, we didn't . Super bizarre experience!
Water & electric only at sites. Has free dump on grounds. Located very near downtown Spokane. Nothing fancy just cheapest place around. Lots of room for thee largest RVs.
