Not value for money, you can simply hike by yourself as it is very simple and relatively short distance.
The Hollywood sign is very far, you will not get social media worthed post picture except you have super expensive pro camera. I use samsung S9 and its still quite bad because its simply too far and to make the matter worse the guide was rushing, so its very inconvenient when you try to make good picture.
To add the wound, she also made a fun of me in front of my husband very disrespectful because I want to take more picture. It seems to me she basically just want finish her job as early as possible. We arrived in the Griffith Park Observatory 10 minutes early and the door not even open. So what is the rush?
This tour only suitable for unfit people you don't exercise at all and u afraid of hiking and only have 2 hours time to kill so the rushing tour guide will suit. Other than that save your money!
The only good thing is she is pretty, fit, remember all the history of the Griffith park and keep asking if you need more water.
