My sister and I did a 2 hour private bike tour a few weeks ago. After 12 days in New York my sister and I are still saying this with the number one thing we did.
Central Park is just gorgeous, there is so much to see and do there. Pearl our tour guide just made this so much better, she is an absolute character. She is a wealth of knowledge on the park but her personality just stands out. It was amazing to see how many other guides knew her and would come up and say hello while we were cycling around.
I've got some sacrum issues and was a little worried about being on a bike for 2 hours but we had plenty of opportunity to get off and have a little walk to break it up.
This is an absolute MUST do - seriously do yourself a favour and request Pearl. 10/10.
