Fort Stevens is the campground for people adverse to "roughing it". There are seemingly more RV…read moresites than "traditional" tent camping ones, complete with electrical and plumbing hookups. Not to mention rentable yurts and cabins, (hot!) showers, (relatively) clean restroom facilities, and even a firewood delivery service, right to your campsite!
Fort Stevens is also massive: miles of hikeable/bikeable trails, sandy beaches, a lake with a boat ramp, a shipwreck, a disc golf course, a military history museum (and gift shop), and several abandoned military installations and batteries to hike and explore. There's more to see and do here than can be experienced in a single camping trip, and after more than a half dozen visits to the park, I'm still discovering new secrets! Also, keep an eye on the various post boards around the park, in which special events, such as storybook readings, put on by the Friends of Fort Stevens, occur on many a summer night.
As I mentioned earlier, this is camping only in the loosest sense of the word, in that you're sleeping outside (well, if you're not in an RV, yurt or cabin). The campsites are relatively small, and close together, but that is also part of the charm, particularly for children: they're all but guaranteed to make some new friends during your stay here, as there will be rugrats running around, skating, riding bikes, exploring, and likely yelling and screaming all around you, for as long as the daylight persists. Intimacy and privacy does not exist here.
There are better places to camp in the Pacific Northwest, particularly for those who desire privacy, serenity, an escape from noise and the presence of others, and a place to commune with and be surrounded by nature (and nature only). Those places exist, but Fort Stevens is not one of them. Despite all that, I have a sentimental attachment to this place, thanks to childhood memories of camping here in my youth. Now, I'm hoping to impart similar memories on my children. Fort Stevens may not be *for* everyone, but it *has something* for everyone. If you can't see that, go get lost in the woods elsewhere.
