Ann Cashman Reserve: At a Glance
- 🐾 The Vibe: Simple, quiet, and friendly, with the relaxed feel of a neighbourhood pocket park where locals know each other and the dogs do too.

- Fencing: Fully Fenced with a secure double-gated entry, so once you’re inside you can relax without watching the gate every few seconds.

Dog Park Features & Amenities
For the Dogs
- Secure Double-Gated Entry: The airlock-style entry means you can get your dog in and out without the usual anxiety about another dog slipping through behind you.
- Calm Social Setting: The contained, flat grassy space is well suited to socialisation in a lower-key environment, which makes it a great stepping stone for dogs building confidence around other animals.
- No Water On-Site: There are no water taps or bowls provided. Pack a bottle and a portable bowl before every visit, not just on warm days.
For the Humans
- Seating Inside the Enclosure: Benches are available inside the fenced area so you can sit and supervise rather than standing the whole time.
- Poop Bags: Not provided. Bring your own bags every visit as this is a back-to-basics park with no dispensers on-site.
- Public Toilets: Not available on-site. Plan ahead before you arrive, particularly if you’re heading out for a longer morning visit.
- No Night Lighting: The reserve is unlit, so it works best during daylight hours rather than as an after-dark option.
Insider Tip: Ann Cashman Reserve does one thing very well and that’s giving you a completely secure space where you can genuinely relax while your dog runs. It’s compact, so it suits a quick daily run rather than a long session, and the double gate means you don’t need to hover near the entrance every time someone comes in. If your dog is small, nervous, or still building social skills, this is the kind of low-pressure environment where real progress happens.
The Final Verdict
Ann Cashman Reserve is a compact but well-designed pocket park in Petersham that delivers the one thing many Inner West dog owners want most: a completely secure fenced space with 24/7 access. You’ll need to bring your own water and bags, but for a safe and quiet neighbourhood run, particularly for smaller dogs or puppies, it punches well above its size.
