I did this walk in early May one year thinking the temperatures would be better than summer and it was definitely a wise choice. It's not a difficult walk as the paths are well defined and it's mostly downhill to the coast. There's an area that is quite rocky and that was the only section I would say was slightly challenging but fairly easy in the grand scheme of things. Make sure you take plenty of fluids and some energy food and don't forget your camera as the scenery is quite breathtaking, especially at the "Iron Gates" area. Grab a well deserved beer at the end before boarding the ferry for the short hop along the coast.
