The best time to visit the hatchery is in September and October, when the salmon return to Issaquah Creek.
The hatchery is free to enter.
There is parking available at the hatchery.
A few nearby places worth checking next.
I have been using it now for 3 months and it saves me so much research. Reduces the need to call and double check every time.
How did I not know these places existed?! Atly's scoring is a lifesaver, now I can finally find THE spot without wasting time Googling my life away.
