Campgrounds and RV parks near Martha Lake, WA

Martha Lake is an unincorporated community in Snohomish County, Washington, roughly halfway between Seattle and Everett along the I-5 and I-405 corridor. The location works well as a Puget Sound base camp: downtown Seattle sits about 30 minutes south, Boeing's Everett plant is minutes north, and ferries to the Olympic Peninsula and San Juan Islands are reachable in under two hours. Nearby private RV parks cluster along the Bothell-Everett Highway and around the suburban edge of King and Snohomish counties. Maple Grove RV Resort and Lakeside RV Park serve travelers who want full hookups close to Seattle attractions, while Lake Pleasant RV Park sits in Bothell north of Lake Washington, a position that lets visitors avoid bridge traffic and tolls when traveling to Seattle, which is roughly 30 minutes away. Port Susan Camping Club, north in Tulalip, offers a saltwater-oriented stay on tribal land, and Trailer Inns RV Park rounds out the urban-adjacent options. For public-land camping, Washington State Parks, the U.S. Forest Service, and Snohomish County parks all manage reservable sites within a short drive.

Private RV parks in the Martha Lake area, including Maple Grove RV Resort, Lakeside RV Park, Lake Pleasant RV Park, and Trailer Inns RV Park, take reservations directly through their own websites or by phone. Summer weekends and holidays book out first, so contact the park as early as possible. Port Susan Camping Club is a membership-based campground on Tulalip tribal land, and access generally requires a member sponsor or affiliated club reciprocity rather than nightly booking. For public sites, Washington State Parks reservations can be made up to nine months in advance of the first date of your trip, with campsite reservations accepted online until 2 p.m. on the arrival date. Bookings run through washington.goingtocamp.com or the call center at 888-CAMPOUT. National park and national forest campgrounds typically open reservations six months out via Recreation.gov.
