The Petticoat Creek Conservation Area's main asset used to be a huge wading pool nicely surrounded by green lawn and small trees. It took me over 350 full steps to circumnavigate the edge of this blue swim spot. Two summers ago, I revisited the place to see the new water area. Where the huge pool used to stand, I found three vast wading pools and a large shallow pool with one beach-like entrance. They also added a huge splash pad, which must look like a giant "rain forest" from a preschooler's point of view. If you miss the old pool, don't! You can still go to Bronte Creek Provincial Park to enjoy their immense shallow pool.
With older kids, you might want to explore the cliff trail going east. You can access it from the paved bike trail, taking the dirt trail leading eastbound towards the trees. It will lead you in 15 minutes to the bridge running over the stream giving its name to Petticoat Creek Conservation Area. (To see more pictures and additional regarding Frenchman's Bay Park at the end of the waterfront trail, read my post describing my last summer's visit to Petticoat Creek and surroundings).
