The lake looks very beautiful in summer. Water activities are relatively cheaper compared to some other places like Lake Tahoe, Hawaii etc. Good place for folks in the Seattle region to go for a weekend. There are quite a few rentals available as well.
Just spent our 6th or 7th straight year at the state park. As usual, it was great.
The biggest change that we noticed from previous years was that the snack shack has stopped doing any fried food. No fries, burgers, etc. I guess if you are after that stuff, you have to go across the street to Alpenhorns.
beautiful mountain views change with each turn on the lake, and the view on the way back to Chelan looks different than the way you came, just by facing the opposite direction. Boat ride is long because the lake is so long, but scenery is well worth it.
