The Trans Derwent Swim is a staple of the Royal Hobart Regatta; and in 2025 it returns on Sunday 9 February.

The swim comprises a 1.5km route across the Derwent River, commencing in Montagu Bay and finishing at the Regatta Grounds, with an allocated 45 minutes race time.

Since its inception, the Trans Derwent Swim has become a must-do for locals, as well as interstate and international visitors. The swim caters for 100+ swimmers, who must brave the dark waters of the Derwent River in this challenging feat.

Feeling adventurous? 1.5km not enough? Consider signing up for the DOUBLE DERWENT.
Traditionally swimming from the Regatta Grounds Foreshore to Montagu Bay and back, the Double Derwent has been slightly modified for improved swimmer safety.
In 2025 the Double Derwent Swim has competitors start at the Regatta Grounds Foreshore, swim to the old floating Hobart Bridge Pontoon (just north of the Tasman Bridge on the western shore) and back to the Regatta Grounds, a 2.5km route, with swimmers having an allocated 1 hour and 15 minutes race time.
