This is the place summer dreams are made of! Hiking, kayak and SUP rentals. Swimming. Glacial rivers and lakes. Wallowa Lake is in the cute artistic cowboy town of Joseph. Nez Perce territory.
The campground itself can get crowded, with lots of families who return every year, but there is so much to do and see in this area, you could spend a month and still not see it all. There are some touristy things up the road, like mini golf, horse rides and a tram that will take you up top the mountain. (I didn't do that because of Covid, although it was open.)
You can rent a boat or bring your own. In June/July the peaks still have snow on them. A bear sometimes visits the campground. Deer will walk through your site. Be sure to be wildlife safe and keep all your food out of reach.
