$12 per night must have the WA Discover Pass ($30 annual)
no one was there our first night and the rest of the days were quiet with few campers. Lovely views, nice walks, nice camp pads, lots of trees to hang the hammocks, flush toilets, but no potable water.
We stayed at Mount Spokane campground in August 2017. The price was $12 for one night and $8 for an additional car. The campground itself is very small (6 spots). They do not allow reservations. It doesn't seem like a heavily used campground, possibly because of it's close proximity to the city or maybe because there are no swimming areas nearby. There was only one other family camping while we were there. Site #4 (where we stayed) has tall trees that provide shade, a bit of a view, and a nice place to put up a tent. Site 1 is shaded by tall trees but it's very close to the bathrooms. Sites 2, 3, and 5 are in the middle of the campground, not much shade or privacy, but great if you have a group of campers that you want to be close to. Site 6 is a pull through for an RV and is fairly private and shady. We encountered A LOT of hikers and huckleberry pickers. There were still tons of berries left to be picked and we saw many people carrying buckets full. Plenty of bike trails, hiking trails, the old cabin you can visit, the Vista House, or you can go to the top where the views are amazing and they have viewing tubes that you can look through to identify the surrounding lakes. The temperature was about 20 degrees cooler than the city, which was a much needed break from the summer heat. We did some hiking and huckleberry picking too and made huckleberry pancakes for breakfast. Overall it was a pleasant little campground and we will definitely visit again.
