Reviews Summary

McNenny State Fish Hatchery offers a free glimpse into fish cultivation and boasts exceptional stargazing due to minimal light pollution. While the staff are knowledgeable, visitors must strictly adhere to weekday operating hours to see the fish, as weekend closures can lead to disappointment. The natural setting also provides opportunities for wildlife spotting. Reddit

"You have a 98 year old father with us and he seen the fish have to sign and got all excited said he wanted to go see the fish we drove all the way back to the fish hatchery on the dirt road and surprised to see that we're not allowed to see the fish you got to go somewhere else that's ridiculous."

Toby Davis

"Star Gazing...
I was at the Fish Hatchery for the peak of the Perseid meteor shower (2023). There's minimal light pollution and it's an incredible area by Mirror Lake.

The night sky was crystal clear and the beautiful Milky Way stretched across the heavens. Between 2 and 4am, I saw maybe a dozen big bright fireballs streak by and many smaller meteorites grazed our atmosphere with more subtle trails. It was a wonderful time.

I also saw 6 deer, 2 raccoon, 1 possum and a Great Horned Owl that briefly landed in a tree near me...it was a busy place!"
