Unbelievable that you can be in this peaceful oasis amongst the skyscrapers. Bike tour was great way to see all the popular spots in park and the hidden North Woods. Guide gave great info on each area where we stopped and was allowed to take photos. Wear a helmet!! There is traffic going to and from park!! Dress for cycling, not time to be concerned about how you look. There is a hill that can be a challenge for a non-cyclist...and most people on these tours are NOT cyclist. Although, it poured at the end of our tour, and we looked like soggy sewer rats...it didn't ruin our experience. However, the company needs to have a "sweeper" at the back of the pack to make sure nobody is left behind.
