Best Tent Camping near Woodinville, WA

The Red Bridge campground is on the very scenic Mountain loop Rd in the Mount Baker-Snoqualmie National Forest. It's a very beautiful drive. Nestled in some great trees, there are 13 sites with shade, right along the river. The camp host was very nice and sold firewood on site. There are no hook ups, and no water spigots so be sure to plan accordingly. There are bear proof trash cans and vault toilets available. Each site has a tent pad, picnic table and fire ring. This campground provides ample hiking, fishing and I saw people kayaking plus its not far to a hike to some glacier caves! Also check out the old red trestle bridge just outside of the campground. At $15 a night you have to see this place. 
I highly recommend Red Bridge campground.

This campground is right next to a state park. It’s also very close to a river and lots of woods. We stayed here to see Olympic national park, (I wouldn’t recommend this location to travel to Olympic every day, it was very far.)

The amenities were nice, bathrooms with warm water (one shower per bathroom.)

No laundry, no Wi-Fi and both Verizon and AT&T worked with about one bar.

The sites were level spacious and had a fire ring and picnic table at each. We chose the full hookup option. Firewood could be purchased through the camp host.

The best part about this day was the surrounding area. Every night, my husband and I would walk to the wildlife viewing platform to see lots of birds, or walk down by the river and see lots of elk and bald eagles.

Every dispersed campground we checked along this road (maybe five or so) was littered with human feces and toilet paper everywhere. We found a literal bucket of human waste beside the river with a soiled pool noodle nearby I can only assume was being used as a toilet seat. Please, if you care about keeping nature wild, carry out your toilet paper and dig a cathole or use the outhouse in the campground. If you don’t know what a cathole is, you should probably should not being using dispersed camping and try the campground down the road. We ended up staying at the campground because we couldn’t find dispersed camping where there wasn’t poop and had a positive experience there. Leave no trace!!

Camped August 8-11 2021 during a burn ban but it was still worth the escape from city life. Temperatures were within the 80s but during our last day, it was in the 90s. There are 2 vault toilets (one by the host area at Site 3 and one by campsite 10). Rented 3 campsites (10, 12, 13) and stayed on site 13 which was at the very end of the campground and I loved the privacy it had. Site 12 had direct river access which was awesome! Site 13 has a trail leading to it but somewhat steep. I would say that it was very clean and well kept. There's only a few mosquitoes but repellants would be ideal. The town is literally less than 10 minutes away in case you need some essentials. There is cellphone reception which is great if you prefer to camp and still be connected. As always, pack in pack out and leave no trace. The only downside is that it is by the road but good thing is there isn't much traffic come night time. Old Sauk Trailhead is about a mile away. You can get Geocaches too if you're into that. 

Missed the campground entrance but the turnaround is just there. Lots of campers seem to miss it the first time (including us). If you're at Site 13, you'll see the many vehicles that stop and turn which is hilarious.
