Mossyrock sits in the Cascade foothills at approximately 670 feet elevation, featuring mild summers and moderately wet winters. Located near Mayfield Lake, most camping areas sit below 900 feet elevation, creating pockets of early-season camping opportunity when higher elevations remain snow-covered. Campsites in this region typically receive around 50 inches of annual rainfall, with most precipitation occurring between November and March.
What to do
Water activities at Mossyrock Park: The park provides direct lake access with a pebbly beach area ideal for launching paddle boards or boats. "The beach itself is pretty rocky, not ideal for just playing in, but great for SUP or boat access," notes Perla H. Swimming requires footwear for comfort due to the rocky shore.
Fishing opportunities: Stocked ponds at Thousand Trails Paradise RV Campground offer accessible fishing spots. "My grandson loves coming here with us the two ponds they stock with fish," mentions John O. The fishing season typically runs April through September with trout being the common catch.
Hiking near Elkamp Eastcreek: Located 30 minutes from Mount Rainier National Park entrance, this area serves as a gateway to numerous trails. A visitor shared, "We spent 1 night at Elkamp and were sad to have to move on so quickly. It would be a great base for exploring the south side of Mt. Rainier as it is within minutes of the Nisquilly entrance."
What campers like
Privacy between sites: Ike Kinswa State Park Campground offers well-spaced sites surrounded by tall trees. According to Christina F., "As we were on the outer part of the loop in a pull-through site, we had a view of the woods and quite a bit of space between neighboring sites. We could not see either of the neighboring sites while sitting by our campfire."
Clean facilities: Many glamping sites near Mossyrock maintain exceptional standards. At Elkamp Eastcreek, visitors appreciate the attention to detail. Shannon H. reports, "Elkamp was very clean with the nicest campground bathrooms we have ever experienced." The bathrooms feature flush toilets and coin-operated showers.
Seasonal atmosphere: During shoulder seasons (April-May and September-October), campgrounds offer a quieter experience with fewer crowds. A Mayfield Lake visitor noted, "I'd recommend this campground in early spring and late fall. IMO it's more for RV camping and boaters... Not sure I'd recommend it at all during peak season, sites are very close together!"
What you should know
Reservation requirements: Many sites book quickly, especially waterfront locations. At Mossyrock Park, arriving prepared with a reservation saves time. Nicholas A. advises, "Arrived after dark, opened up gate, self registered in the main campground. $30 is a lot for a space to park overnight."
Cell service variations: Connectivity varies significantly between campgrounds. Christina F. shares about Mossyrock Park: "I have Verizon and was able to call and text my husband and occasionally use messenger. I had one or two bars. Probably would have been better with a cell booster."
Water level fluctuations: Lake levels can change dramatically throughout the season. One camper reported, "Only damper to this year was the dam in Tacoma was partially drained causing a 'low tide' which exposed the dirt and poor beach area... usually when water is at normal level the beach is all sand and water is clean and clear."
Tips for camping with families
Playground access: Seaquest State Park Campground provides dedicated play areas for children. Mary C. notes, "My kids loved the addition of a playground. Many parks don't have this and it kept them entertained for hours. There is a bathroom and extra parking right next to the playground."
Swimming considerations: For families planning water activities, timing matters. The swimming areas are typically most comfortable between mid-June and early September. One visitor warns, "The swim area itself is pretty pebbly. More fun with sandals," suggesting proper footwear for children.
Biking opportunities: Several campgrounds feature flat loops ideal for children learning to ride. "Very family friendly they have a (very) small playground. Lots of room for kids to ride bikes," shares Kristina H. about Lewis & Clark State Park.
Tips from RVers
Hookup availability: Alder Lake Park offers various utility options for different camping styles. A camper explains, "We stayed at a full hook up campsite that included electricity sewer and freshwater." Water and electric hookups cost approximately $35-45 per night while full hookups range from $40-55 depending on season.
Site leveling challenges: Many sites in wooded areas require leveling blocks. One visitor to Elkamp Eastcreek notes, "The campsites are far enough apart that they feel relatively private, and most appear completely level." Always bring leveling equipment as terrain varies significantly between campgrounds.
Dump station access: Not all glamping sites in Mossyrock offer on-site dump stations. William B. advises, "What would improve Elkamp? It would be great to have a dump station. Sewer hookups would be even better. But that's a small inconvenience in exchange for staying at a gorgeous campground just a short drive from the Seattle metro area."
