Trillium Lake Campground is a quintessential family campground. The reservoir is ideal for paddling or swimming on hot summer days, there is a fishing platform for those who prefer to remain on the bank, and a short, 2-mile hike loops around the reservoir. There is a classic campground amphitheater that is perfect for late night horror stories, and the campground offers an extensive day use area with a picnic shelter and stand-up barbeques. And of course, there are beautiful views of the state's tallest mountain.
What Trillium Lake Campground doesn't have, however, are campsites that are easy to reserve. Make your summer weekend reservations early. Campsites 58-64 are located on the south side of the lake, just west of the dam, and as of summer 2012 a yurt was being installed at site 61.
