Weir Reserve

Nice hidden park away from the busy roads. Most people don’t realise it’s there on the far side of the Rowers.
If you’ve got kids, bring some cardboard to slide down the hill towards the river on (don’t worry, plenty of room to stop safely — they won’t go in).
In spring the small Japanese gardens will be in bloom. They’re popular with weddings though.
Plenty of open parkland, seats & tables. Bring a picnic blanket and soak up the sun while looking out over the Nepean or just relaxing listening ot birdsong near some trees.
