Are there any places in North Houston where I can sit alone, without being disturbed?

Hey, I just want to ask are there any places you can recommend in North Houston where I can sit without being disturbed and relax after 10-11 pm, like a park or a lakeside in Lake Woodlands or Lake Conroe? There may be places like cafes that are not crowded, but they are usually closed at that time. Or can you recommend a driving route where I can drive around and relax?
