Starting with brunch at Arnie's Cafe on Rymill Lake, navigate the best way you can around the 'big dig' O'Bahn works, and through the part of the parklands that becomes the Garden of Unearthly Delights during the Adelaide Fringe.
You may note the former play-lake in a bygone less public health-aware era, now filled with grey dolomite gravel that comes alive with the Feral Aussie Boulistes Petanque Club on Wednesday evenings and Sunday Mornings. They welcome visitors, and from personal experience, they are a great bunch of people.
The Botanic Gardens need no explanation, though two things are worth noting. 1. If you are on your bike, you will need to dismount and walk 2. Diggers Shop is a must visit, with hundreds of organic seeds for sale in their seed library, and unique gifts, seedlings and advice abound.
Just east of the Zoo, the path leads down to the Torrens and across the bridge and up to the Hackney Bridge. This part of the Torrens between Hackney and Frome Roads is delightful, with some excellent places to stop and have a private picnic for two or a crowd.
Across the bridge, you can either head down Melbourne St for its of skip by to the East, and around near the horse paddocks of the Northern Parkland.
Skirting by the Glover Playground - North Adelaide with its iconic Helicopter and free swap-library for kids, the pathway heads to another new section of path that tangents by the arguably best Dog Park in Adelaide.
And then back to the starting point for this four part journey near the Caledonian Hotel.
