When planning to island-hop in Greece, it's important to consider the following tips: Choose a group of nearby islands to minimize travel time, like the Cyclades or the Ionian islands. - Use ferries for transportation between islands, and book tickets in advance during peak season. - Pack light, as ferry travel can be easier with less luggage, and many islands have cobblestone streets and steps. - Stay flexible with your schedule, as ferry times can change due to weather conditions. - Consider staying on each island for a few days to truly appreciate its unique character and attractions. - Check for multi-island ferry passes or discounts that might be available for savings on transportation.
