This was the ideal spot for our week-long trip, staying in the foothills of Mt Rainier. Surrounded by trees (the land is an old Christmas tree farm!), a hiking trail on property, dog friendly, full hook-ups for the RV and plenty of space, an hour from the trailhead in the park, and the sweetest hosts. Would absolutely encourage any camper(s) looking to spend some time in a quaint mountain town close to Rainier, to stay here!

Weekend Trip to Williams Park campground

Definitely a must camp here! End of September so everyone just had been there for fishing season. Pretty much had the place to ourself. Everyone here is so welcoming and kind, we had full hook ups a few steps away from river and lots of land to have peaceful hikes. There a little house with just a full kitchen, washer and dryer and bathrooms even with a shower. A quick 35min drive from Astoria which we spent one of our days at. The lady assisting the owner was so kind to give my kids a golf cart tour of the dry camping area and were the walking trails are at. They loved it!!! Everything very well managed and cared for here. I do like to be able to drop trash instead of haul it back but not a deal breaker we will definitely be back.

My wife and I had a great stay at Glorya’s. It served as the perfect base for our Mt Rainier explorations. Hookups worked great and the spot was level and private. Easy getting in with our 35’ fifth wheel. She generously shared her knowledge of the local area (as well as some of their garden bounty). Her background as a massage therapist came in handy when I had low back issues. Her kindness and helpfulness went above and beyond any expectations that we had. Easy conversations with her and Jimmy. We felt like part of the family. We arrived for a site and left feeling we made new friends.

We loved camping in the Lone Cherry Grove! The site was just the right size for three tents, two hammocks, and parking at the edge. You can tell Justin has thought of everything. The shower was cold only because I didn’t wait for it to heat up—but it felt wonderfully refreshing. The fire pit is dreamy: large enough to cook over and gather around, with a wide gravel circle for peace of mind about stray sparks. Even the portapotties were spotless (a rarity!) and came with the promise of cleanup if needed. The handwashing station next to them had soap and doubled as a place to fill our fire-safety bucket. Justin stopped by once to refill our water and check in—thoughtful without ever intruding. He was also quick to reply on the app and even answered when I called to confirm our site, which made arrival stress-free. The land is flat, forested, and peaceful, with a beautiful walking trail that loops the property. If you want to step away, there’s a river, gas station, and burger joint only seven minutes out. Our group of six all agreed: this Hipcamp is a hidden gem, and we’d love to return!

We had a wonderful time at the lavender farm! The Lone Cherry Grove spot is secluded enough to feel like you're deep in the woods, but close enough to the owner's property that we felt very safe. The fire pit was the perfect ending to the busy day that we had before arriving, and we got a surprise visit from the very friendly farm cat while we were relaxing. The site is very close to a very clean porta potty. We didn't even heat up the water for the outdoor shower and it was incredibly refreshing. We arrived just after cut your own lavender season ended but were still able to buy some of Cowlitz Farm's products that Justin personally delivered to our campsite. They smell incredible! We would definitely stay again.

Very cute and calm spot for camping. The campsites are very far apart so you have lots of privacy. We had a well maintained gravel area with a fire pit, a bench and chairs, and even fire wood and tools to set up the fire. We lived the fast that our dogs could be off leash! When you arrive at the farm, drive to the grey container and there’s a map with the campsite numbers there. The porter potty was full, but I guess it’s due to the long Labor Day weekend.

I really enjoyed camping here. The campsites were large and spread out enough that you definitely felt like you had your own space. My dogs and I enjoyed the trail around the property every morning and I loved the mountain views! I didn’t have a campfire, but there is a very nice fire pit and the wood is easily accessible. I appreciated the shower after my dusty hikes!!

We loved the Shady Escape. Originally booked the full hook up site, but they offered the back open wooded field spot since we had extra campers. It was so serene and peaceful, but also had great WiFi and cell service. We had a 40 ft travel trailer and friends had an overland camper. The area was perfect for us and the dogs. The hosts are so wonderful, they provided a fire pit and corn hole. The location is close to mineral lake for fishing and Rainer base camp and Elbe. Our group had a great time, we will definitely visit again.

We had a very nice site, with a nice view of the lavender field during the day, a good night sky view. The site was well set up for our trailer and would be great for a motorhome as well. The location was good for both Mt Ranier National Park and Mt. St Helens.

It was easy to find, hassle-free getting to the actual camp site, which was beautiful! The lavender farm property is gorgeous with a number of amenities. No light pollution at night made for an incredible view of the stars. Close to lots of outdoor recreational opportunities. Bonus: you can order items from the lavender farm’s gift shop ahead of time and they kindly deliver to your campsite! I highly recommend this location.
