Coho campground is a wonderful spot but it is a 35 miles off of the highway. If you go, pack everything you need. There are no stores or gas stations once you hit the paved road to the campground. The camp host does sell firewood and ice. Half of the campground is first come first serve. Reservations can be made on the other half. There is also a boat launch and a huge day use park. The reservable lake spots 29, 31,33, 34, 35, & 36 sit on a bluff overlooking the lake. These are the prime spots. The bathrooms all have flush toilets but no showers. There are showers at another campground a short drive away. Even when the campground is full on the weekend it doesn't seem crowded. Lake noise from powerboats, even though there is no speed limit on the lake, is rarely an issue. It can rain a bit at Coho so bring tarps. Like almost any campground in Washington State the campground empties out on Sunday and is almost empty during the early part of the week.
