One of my favourite off-leash parks! The ground is mulch which I prefer to grass - makes picking up messy #2s so much easier!
The busiest times are after work hours and weekend afternoons-evenings. Due to the location, there's often little to no traffic outside of this time. I've come many weekdays and typically have the entire park to ourselves, which can be a good thing if you want to run your dog off leash but can't have him/her around other dogs.
The path around the pond isn't technically off leash but many owners do off leash their dogs since the majority of the people who come to this area have dogs too. Just a heads up: I have gone during off peak hours though and sometimes run into moms with strollers and toddlers, so just be aware in case your dog is reactive to strollers/children/people without dogs!
