Two walkways - my fave, turn left from ferry terminal and take a nice amble along water edge, with pleasantly manicured lawns, a marina, swimming bays (with shark nets), pretty flowers and plants, and posh houses to peer at.
Or/and... Turn right from ferry terminal,walk through a pleasant shopping street (Visitor Information on nearest corner), meander up to beach, and you have another lovely walk with sea views, many passers-by (and their dogs), and cafes and restaurants at main Manley swimming beach. I much prefer this beach area to Bondi.
There is a nice market down main shopping streets on Sundays.
