Need help finding a place to camp from tri cities over memorial day!

[syoungs]

Looking for suggestions on where to go camping this memorial day, I'm tired of the tucannon, especially on busy weekends.

Looking  for dispersed camping, no amenities needed, though a vault toilet would be nice for the wife. Would like to be close to some trout fishing for the kids, though not a deal breaker if not, and I'd like to stay within 2-2.5 hours from the tri cities, though I could stretch that a little.

Wouldn't mind the trip to get around colville/chewelah, would like to learn more of that area for sure.

Were gonna be a group of 6-8, in tents only.

Thanks for any help!

Seep lakes below O'Sullivan dam. Lot's of places to explore and fish.

I'm sure it will be packed, but the Sun lakes has quite a few camp areas, and lots of fishing. Maybe Banks Lake? All good area.

Seep lakes offers lots of places but no campfires after some date in April
