This is the last year Vali's will be open.  If you've never been head you still have a chance and if you love it as much as we do then this is your last call.  

The campground at Wallowa lake is a great one.  The little town at the far end of the lake is a destination.  So many fun things to do and lot's of great places to eat, but seriously don't miss Vali's (make reservations before you leave home) for dinner and donuts on the weekends.  Amazing food and even more amazing people.
Riding horses in the Eagle Caps is one of my favorite childhood memories.  My parents would never go with me but the guides were always great.  Now I send my kids.  Putt putt golf and go-karts also make for some great memories and are easier for the whole family to enjoy together.  The lake itself is great for skiing and there are several docks to borrow for the day.  Camp and marina staff are pretty friendly and keep the place looking great.  Go to here.
