Set among old-growth forest near the Sol Duc Hot Springs Resort, this campground offers a genuinely different Olympic experience — mountains and mineral hot springs rather than coast or rainforest. Sites offer flush toilets and potable water, no hookups, and the campground’s proximity to the resort means a hot springs soak is an easy add-on to camping here, along with access to the Sol Duc Falls Trail, one of the park’s most popular short waterfall hikes. Given the resort and trailhead draw steady visitor traffic, reservations for peak summer season fill up well in advance.
