Cool places to visit in Houston or other parts near Houston? Potentially for vacation?

My boyfriend came from Canada 2 years ago, and I've been in Houston for the past 16/17 years. We're both 24. I came from Los Angeles, so…. things imo were a bit of a downgrade when I came here. I love Houston and consider it my home, don't get me wrong, but there was a lot more to do in LA.

We love Houston food, but I also want to try other cool things. I loved the LA Aquarium, but the one here is not great imo. The one in San Antonio was probably worse. We enjoyed the riverwalk in San Antonio, and I like Buffalo Bayou park here in Houston. In fact, next time, we want to bike there. I liked Little Woodrow's bar for the turtle races, but I'm not a bar person. He doesn't drink much. I love Montrose for the clubs, but he isn't a club boy lol.

I have been on those "what to do in Houston" pages, and I… am not enthralled 🙁 I been to the Space Center, Discovery Green is cool for a little bit, and then idk what else to do.

Can you guys help me out? Even if it's in Galveston or within 4-5 hours, we don't mind. We do like nature. We are planning on taking a mini vacation of 2-3 days in Early February. We both would like a vacation as he is burnt out from work and I just finished nursing school and will have taken my NCLEX

thanks so much guys!
