You should hook up with the High Country SUP Group!
Cougar Bait and Big Tall are the Team Riders in Canberra; they run a Sunday Social Paddle every week leaving from Monlonglo Reach (in front of the Burley Griffin Canoe Club Boat Shed) at 0800 and they paddle to Regatta Point. They usually have a coffee at the Deck Cafe and head back to the Reach by 1000. Any first timers or beginners usually turn up at 1000 for a try out/practice session. Joining and paddling with the group is free, as is having a try outpractice paddle at 1000.
High Country SUP is on facebook; just search for the group and request to join!
