I was travelling on my own and came across a flyer for the tours. To start - Ken is brilliant. Extremely helpful, courteous and knowledgeable. The tours are very reasonable for the price, and even better they collect you from your location in Santa Monica. Marvellous if you don't have a car. I did the Celebrity tour (not usually my cup of tea, but the history of the area was fascinating) and the sunrise hike. The hike isn't massively exerting, but it is beautiful. Well worth doing. If travelling on your own it's lovely to do. Highly recommended - Thanks Ken!
