What to do
Hiking along river trails: At Tolt MacDonald Park, trails wrap around the Snoqualmie River with multiple access points. "There are also short forest trails for an easy hike or post-takeout digestion walk," notes Saraj B. about nearby Dash Point State Park.
Water recreation opportunities: The Green River at Kanaskat-Palmer State Park provides calm spots for fishing and wading. "Short hike to river spots that are perfect for wading or fishing. 10 minute drive from Deep Lake which is beautiful and great for swimming and paddle boarding," shares Ashlie M. The park's river section requires skill for kayakers.
Miniature golf and swimming: Family activities extend beyond hiking. "The pool, miniature golf, playground and basketball were great," writes Isabel G. about Tall Chief Campground, where recreational amenities remain open during extended camping seasons.
Wildlife viewing: Lake Pleasant offers quieter wildlife observation. "The grounds are quiet... truly silent... save for the many geese that call the lake in the center of the property their home," explains kristin S., noting the walking paths around the property's ponds.
What campers like
Private camping spaces: Despite proximity to urban areas, some campgrounds offer secluded sites. At Tall Chief Campground, "Most sites are pretty big too. We can easily fit our trailer, tow vehicle, and extra vehicle and still have space!" according to Brodie D.
Convenient access to services: Campgrounds position campers near essential services. "The park is across the street from a Safeway which was very convenient. Also very close to some excellent restaurants in Bothell," notes kristin S. about Lake Pleasant RV Park.
Well-maintained facilities: Clean bathrooms rank high among camper priorities. Julie M. found that at Kanaskat Palmer, "Bathrooms are super nice - each is private with a shower." Similarly, at Vasa Park Resort, "The bathroom, laundromat, etc are sparkling clean," according to Ralph D.
Beach access: Water features enhance camping experiences. "Great campground right on the beach. Clean facilities," says Brook M. about Fay Bainbridge Park, which offers direct shoreline access.
What you should know
Noise considerations: Proximity to urban areas means some noise disturbances. At Issaquah Village RV Park, "you'll be camping 200' from I-90. But we found our ear plugs did a good job of quieting that noise enough for us to get a good sleep," shares Jerry B.
Park ranger presence: Some campgrounds maintain strict oversight. "This campground is heavily patrolled by the park rangers. I usually have contact with them in my campsite at least twice a day," explains Kelly P. about Kanaskat-Palmer State Park, noting this keeps the campground "safe and pleasant."
Pet area limitations: Not all pet-friendly campgrounds have on-site pet areas. At Issaquah Village RV Park, "you have to go outside the park and across the street to hear compliant pet owner," according to Melanie A., requiring additional planning for pet exercise.
Cell service variability: Reception varies significantly between and within campgrounds. At Tall Chief Campground, "I would say arrive early so you can drive by all the sites while checking to make sure you have good reception if you need it... I'm getting 120+ mbs download on AT&T in my site right now, but several sites down from me, it can dwindle down to 5mbs!" advises Brodie D.
Tips for camping with families
Look for dedicated play areas: When selecting pet-friendly camping near Mercer Island, Washington, prioritize campgrounds with children's facilities. "Amazing kids area pirate ship. Great beach walk and good camp sites," shares Tanya B. about Fay Bainbridge Park.
Consider location proximity: Select campgrounds based on planned activities. "This is a perfect place for dropping your mobile hotel room and explore Seattle and the surrounding areas," explains Mareesha B. about Trailer Inns RV Park, noting the 10-15 minute drive to downtown Seattle.
Check swimming options: Water features provide entertainment for children. "The day use area is very nice, and right on the water; the campsites are located away from the water and look just ok," notes Lee D. about Saltwater State Park, indicating families may need to walk between camping and swimming areas.
Book early for summer stays: Limited availability affects peak season camping. "We got lucky and snagged the very last spot here on a Saturday in late September," shares Laura M. about Kanaskat-Palmer State Park, suggesting advance planning, especially with pets.
Tips from RVers
Hookup limitations: Many campgrounds offer partial hookups only. At Lake Pleasant RV Park, "They have water, propane, and a dump. They also have great long-term rates," reports Love W., information particularly relevant for extended stays with pets.
Site levelness varies: Some campgrounds present challenges for larger vehicles. "The gravel pull through was so not level the jacks pushed the front tires 6 inches off the ground," notes Cody F. about Kanaskat-Palmer State Park when dry camping with a 30' motorhome.
Power considerations: Electrical capacity differs between campgrounds. "Normally 30 amp posts are sufficient but we ended up here during a heat wave and an entire section of the park blew after having several days of power issues," reports Derek & Alex W. about Tall Chief Campground, suggesting checking amperage needs for climate control when traveling with pets.
Storage options: Some campgrounds accommodate travel interruptions. John M. notes that Lake Pleasant RV Park has "a small storage lot that can accommodate short storage. I camped, stored my camper while I went on a cruise, camped and then headed out," which helps when coordinating pet care during multi-destination trips.
