Learn Spanish (Latin America): Conozco un lugar divertido cerca del parque.

Yes! Conocer is a regular -er verb in most of its forms, but its yo (I) form is irregular. Instead of just dropping the -er and adding -o, we add a 'z' to make it conozco. Forms for other people stay regular, like tú conoces or él conoce.

I learned that "I know" is sé. Why use conozco here?

Spanish has two verbs for "to know": saber and conocer. You use conocer when you are familiar with a person, place, or thing (like "a fun place" in this sentence). You use saber (where "I know" is sé) for knowing facts, information, or knowing how to do something.

Why does the sentence say lugar divertido instead of divertido lugar?

In Spanish, descriptive adjectives like divertido (fun) usually come right after the noun they describe (lugar). So, you literally say "place fun".
