Best Time to Visit Greece
For budget travelers, the shoulder seasons of May-June and September-October are ideal. During these months, ferry prices are stable, hostels are cheaper, and the weather is perfect for hiking without the sweltering 40°C heat of July and August. Most free outdoor attractions remain open and far less crowded than in the peak summer months.
Currency & Money
Greece uses the Euro (€). While credit cards are widely accepted in cities and on most islands, carrying cash is essential for small family-run tavernas, street food stalls, and bus tickets bought on board. Tipping is not mandatory but rounding up the bill or leaving 5-10% at a sit-down restaurant is a nice gesture for good service.
Getting Around Greece
The KTEL bus network is the backbone of budget travel in Greece, connecting almost every town and village with reliable, affordable service. For long-distance mainland travel (like Athens to Thessaloniki), the Hellenic Train offers a comfortable and scenic alternative. Between islands, 'Conventional Ferries' (like Blue Star) are significantly cheaper than high-speed catamarans and offer a more traditional Mediterranean experience.
