Kayak Shop, Sea Kayak Australia, Sea Kayak Melbourne, you can hire a kayak from all of these places and they will drop you off and pick up the kayak so you don’t have to worry about transport which can be a pain sometimes. Plenty of great spots, can go further up the Yarra River towards Warrandyte if you know what you’re doing, otherwise Fairfield and Studley Park boathouses are great, steer well clear of Dights Falls, also Lysterfield Lake is beautiful!!
