Yup, well and a ferry if you start or finish somewhere in the middle but you can drive the whole loop. There's at least one night in the whole trip around though, even more in Summer when you can make all the stops. Sol Le Duc hot springs, Numerous waterfalls, Hundreds of hikes, multiple lunch stops, a couple of towns, three entrances to ONP, several beaches, and even a casino if that's your thing (not mine, lol)
