We took a chance and went to Cheltanham Badlands on Monday morning without reservation. It was fully booked so we moved to Terra Cotta Park, about 10 minutes from Cheltanham Badlands.
Entry ticket is $7 per adult, no vehicle fee.
It is nice park with lots of open space, trails and picnic areas both sheltered and open sky. We covered quite a few trails as these trails are not long – McGregor Spring, Vaughan, Terra Cotta Lane, Wetland, Graydon and Forest Meadow.
