Touring spot in Houston!!

Just moved to Houston last week, and I have some time to explore the city. Do you guys have any spots to recommend? When chatting with a bank teller, she was like "I’m in Houston for thirty years, but there isn't much to do in Houston…" and I as well am having hard time finding spots that seem interesting. I love nature and inhabitants, so will be visiting parks and preserves, but any recommendation is appreciated! Fyi Im 25f.
