Admission and parking are Free! Get to see the old trains and walk around the museum learning all about them. You wont spend all day here but It's fun for kids and it's just a nice place to check out and you'll be able to take some great pictures. Bring a lunch and enjoy it on one of the picnic tables. ( located at the back entrance of griffith park - off of the 134)Right next door are the old steam engines (a separate area) only open on Sundays also free but they do accept donations since you are able to ride the steamers.
