The north entrance to Lake Wenatchee State Park contains the RV spots, both utility and non-utility. The south entrance appears to be only for tents. The "utility" spots are located on the outer edge of Loop 1 and Loop 2 of the north entrance. The utility sites contain a "half circle" RV parking spot, on dirt, where you "bend" your RV around the half circle in order to connect to the post (more difficult with the larger rigs!). The "half circle" was very uneven, but it's a forest, what can you expect? I use Lynx blocks and I gave up trying to get level. But, on the good side, along with your RV parking spot, you get a very spacious picnic area and a tent pad. TV reception via antenna was sufficient, not perfect, but sufficient. You can get the networks and PBS. A popular lake and boat ramp are within walking distance, and there is a store for some supplies. If you choose to dry camp, the non-utility sites in the north entrance have good back-in slots with the same spacious picnic area and tent pad. There are sufficient trees for adequate shade, but spaced far enough apart that privacy is compromised. You can see all your neighbors and they can see you! The reason for the trees being spaced apart is the result of a posted forest management plan which actually made sense to me, even though I'm not a botanist or vegetation expert. I enjoyed my stay despite sleeping very unlevel.
I showed up at Deception Pass State Park on a Saturday in April, and managed to get an electrical site. However, I'm sure once it's summer, you need reservations. If you reserve online, you are charged a "reservation fee." Excuse me, how does this "encourage" us to use the web? Spots 1-78 are electrical, and they even have 30/50 hookups! No cable, but I got decent reception on the antena. I had spot number 40 and it was relatively level, despite being a dirt campground in the trees. I enjoyed my stay there, and would have liked to stay longer.
If you want a good place to catch up on some reading, Brooks Memorial State Park is it! You have no television reception at all unless you have a satellite. (I thought it was interesting that the small, privately owned RV park next door charged $1 less for full hookups with cable TV!) I came here hoping to escape a record breaking 95 degree heat wave in the month of May, of all things!!! The camp host told me that although Goldendale was suffering the same 95 degree heat that my home was, this park was high enough in the mountains that there would be an extreme temperature drop in the evenings. The host said, "You'll need blankets." I opened all windows, and woke up at 3:00 AM to a refreshing 50 degrees. This campground has a front side and a back side. Although the front side has shady spots, the camp host said the back side gets a breeze that does not hit the front side. In addition, the host suggested sites 19 or 20 (on the back side), "If you don't want the heat." The host was right, those two sites got morning sun, but afternoon wasn't too bad for the heat. The only downer is that spots 19 and 20 are real close to power lines. You wake up to crackle crackle crackle, and having crackle without the "pop and snap," well. According to the brochures, this park is popular in the winter with the snow-shoeing and cross-country crowd. I enjoyed my very quiet, two day stay here! There are tent sites as well as water/sewer/50 amp electric.
This is a small State Park in the Olympic National Forest system. There are 37 campsites, of which 18 are utility (30/50) sites, 17 are tent sites, and 2 are for bikers/hikers. This park does not take reservations, it's first come, first serve. It was August, mid-week (Wednesday), and I arrived around 11:00 AM. Campground was half-full, with only a few utility spots available. By Thursday, it was full (and kind of noisy!!!)! The camping spaces are "crammed" together. There are lots of trees for good shade, but you can still look out your window and wave to your neighboring camper. Some of the utility slots are back-in, and some are "half-circles" (try "bending" your RV around that slot!). If your RV is larger than 30 feet, you may not fit in any of the utility spaces, let alone trying to get into them! The driving road through the camping area is narrow and runs up and down hill in a circle with sharp curves. I had a back-in spot, but trying to back in was laborious. Fortunately, a very nice young boy from the neighboring camping spot offered to help me get in. The utility sites have an adequate place to pitch a tent next to your RV, and a fire-pit and picnic table. TV reception via antenna is adequate, not perfect, but adequate. There are hiking trails, and there is a beach across the highway. Next door to the park is a public RV resort with a laundromat, but I'm not sure if you're "allowed" to use the laundromat if you are staying at the State Park. I stayed two nights. If you leave your windows open while sleeping, you will hear the traffic on US Highway 101, even at 3:00 AM!
