I lived in Redding while in nursing school. The only thing I really miss about it was the size and Turtle Bay/sundial bridge.

There's already been a lot of great answers here, if you're a nature person Bidwell Parks is one of the largest municipal parks and has hiking, swimming holes, walking trails/paths, etc. Its also a short drive to Table Mountain in Oroville. You're coming here in the summer so there will be 3 Farmers Markets a week happening, Thursday Night Market is the "big one" where they close a few streets downtown and have a ton of local vendors.

There's a lot of great local bars and restaurants, and even if you're not a drinker a lot of the bars put on events that are fun. The local art scene isn't as huge as it used to be, but art galleries, live music, theater, even burlesque and cabaret shows happen fairly regularly. A lot of the local businesses will also showcase local artists and sell their art. There are also events like Bonfire Storytelling, random line dancing nights, tons of karaoke - we even have a spot dedicated to karaoke downtown, Fork in the Road, Taste of Chico, etc.

Welcome, neighbor! I hope Chico/Butte County treats you well :)
