From Arlingon WA. Go north on I-5 to Hwy 20. Take Highway 20 west to Anacortes. When you come to a T, turn left. Next T, turn left again. The road will wind around, pass a cemetery and at the end of the road there should be a little sign to turn left for Whistle lake. Turn there and it will eventually go to gravel. There will probably be a number of cars in the parking lot. It is about a one mile hike in. Have a nice flight.
