Really hard to give you info without first know where you want to be. Best park, and one of the most expensive, is Lake Pleasant in Bothell. Very nice park, but it is $44/night, no weekly or monthly rates in the summer. We have also stayed at Lakeside RV Park in Everett. At little hard to maneuver a rig into the spot (and out again) but easy access from I-5 and considerably cheaper (~$13/night) than Lake Pleasant. Once in, it is reasonably quiet at night even though it is off of a major road (Highway 99) in the Everett area. Both of these are FHU.

If you want on the east side, in Fall City is Snoqualmie River RV Park - w/e right on the river at around $33/night during the summer and Issaquah Village at $44/night FHU. We like Fall City, but stay at Tall Chief which is an Encore park, under Coast-to-Coast.

There are some on the south side of Seattle (a KOA near the airport) but in good conscience I can't recommend any of them.

I agree with Barb. On the off chance you are an Elk, there are some lodges in the area with camping.

If you're willing to stay in a southern suburb of Seattle, the Puyallup Fairgrounds offers FHU for $23/night, cheapest anywhere in the Puget Sound region. You'll be camped in a grassy field next to the Fairgrounds. For us, that's ended up being our best option, we used to live in the South Sound, so we will use this as our base this summer while we're in the area for 3-4 for doctor, dentist, family, friend visits, etc. Plenty of access to shopping, laundry, etc. in the area.

Call ahead of time for the $23/night rate, if you pay at the campground it's $30/night, cash only. Of course, this assumes you won't be there during September when the place is occupied by vendors for the state fair for 3 weeks and not available to the rest of us during that time.

Agree with Barb on the other places, definitely avoid the KOA in Kent, it's really tight, horribly expensive, only redeeming quality is that it's close to the Green River bike trail, but still would not ever consider staying there and we have friends close to that location.

Oh, great! Thanks so much for the information, Barb. Will call right away. Pat K

Kitsap Memorial is closer to the ferry, however you will need to drive to the ferry, wait for the next available one which could be anywhere from 20 minutes to 2 hours. You might want to map these , I think Kitsap is closest to the Kingston / Edmonds ferry which still leaves you an hour drive to Seattle, depending on traffic, or you could drive to the Bainbridge Island or Bremerton ferry, but I think you would spend more time getting across the Puget Sound using ferries than you would driving from Puyallup. Kitsap Memorial would be the least desirable state park of the 2 choices, sites are close together and you get noise from the state HWY. Fort Flager is a nice state park with lots of beach access, but a long slow drive from anywhere, we used to go there to get away. Kitsap does not have beach access.
Another option is TalL Chief RV park in Sammammish, distance wise it's probably closer than Puyallup, but you have to cross a toll bridge into Seattle and traffic generally backs up getting across the bridges.
If you don't want to drive, check the Seattle transit schedule, there is a train option from Puyallup that's not too far from the Puyallup fairgrounds, which might be a much cheaper option vs, Seattle city parking.

Actually, you can also take I-90 across Lake Washington and it is closer tha WA 520 going across. We love Tall Chief, and spend a few weeks there each summer.

Ok - thanks for all the info! Just found out my cousin lives on the north side of Seattle, closer to Marysville (I think?). He suggested Flowing Lakes County Park or Kayak Point County Park (guess he knows weekenders that go there). He said he thinks it is an easier ride than from the south or waiting for ferries. Thoughts? Does anyone know anything about these parks/areas?
(My cousin doesn't camp and while suggesting these b/c of locale - might not "see" or understand all things someone with a 40' long, 13'5" high 5th Wheel has to consider)

Thanks again!

Kelly, one more thing to consider, if you are there the last week of April it's going to be wet, April starts to see sun breaks but if you are camping in trees you are also likely to have some mud. Not sure what it's like now but I don't recall any paved site or paved road at Flowing Lake, I think we were last there in 2006 so it might be better. We were ther in July when it was warm but the park was still dark. I personally don't like camping in chilly, heavily treed parks when it's raining, it always seems dark and that is what you are likely to get in April, Lake Pleasant would be a better choice that time of year and while the camping might be more expensive you will probably spend less in fuel getting into Seattle.

Thank you guys so much! Great tips, ideas and suggestions! Definitely going to check out the casino! If not - will call to find out more about Flowing Lake. We usually like the County Parks.
