There are three main battlefield areas - Cape Helles Turkish: Seddülbahir, Anzac / Pine Ridge and Suvla Bay which has fewer places to visit. Depending on how detailed your itinerary is, it would be possible to visit the main sites of interest, particularly around Cape Helles and Anzac/Pine Ridge, in a single day. More realistically, two or three days allows plenty of time for an extensive tour, taking in all the battlefield sites, cemeteries and memorials. Must sees include:
Be aware that despite what certain tour operators will tell you it is entirely possible to attend the Dawn Service on ANZAC day independent of a tour group. There are taxis from Ecebat and private vehicles and pedestrians are admitted free of charge into the park during this time. This saves arriving in the evening of April 24th and freezing overnight waiting for the service at 5:30am on the 25th April.
