As Renzo said, try setting up informational interviews with attorneys. However, this won't give you a real feeling of what they do. Perhaps try doing some job (basically anything outside of the mail room, janatorial, or cafeteria) at a firm to get an idea over a summer. I'd suggest trying to find a smaller firm, since you'll have more ability in most small firms to see what really happens than at most large firms, especially as an undergrad.
Feel free to PM me for more.
Edit: Also just go sit in different courts to get an idea of that. Even though it isn't a huge part of many lawyers' jobs, it shows you a few different types of law and one aspect. (It could be a big aspect for you, depending on what route you go.) Go to the criminal, civil, probate, etc. courts - whatever is plausible. Don't feel odd sitting there alone, even with a notepad. Most people in there don't notice or care about the people other than the ones they know. Also, dress nicely, please.
