Thunder Action Sports brought their jaw-dropping BMX stunt show to the popular Bogside park at part of an action-packed Lift Off event.
There were also trapeze artists, football skills and games throughout the evening.
Here is a selection of photographs from the Lift Off event which took place on the last evening of a hugely successful Féile programme this year.
