An amazing place to stay with kids. Plenty of space for them to play, plenty of things to explore.
Byron city center is a bit far away (google says ~25 min walk which is about right) so be ready to walk a lot if you don't have a car or other means of transportation. There're bicycle lines nearby but I failed to find a decent bike with baby seat for hire.
The nearest Tallow beach is nice but it's an ocean beach with big waves so might not be good for little ones. We still enjoyed it a lot but the rock pool near the Pass is definitely the winner.
Otherwise it's an amazing place that we didn't want to leave and wish to stay longer.
