What's a good 3-day itinerary for Crete?

Day 1 stays in Heraklion. Get to Knossos by 8am, before the tour buses from the cruise port arrive around 9:30. The site sits 5km south of the center. A taxi costs about 8 EUR. Settlement here dates to roughly 7000 BC, making it one of the oldest continuously occupied spots in Europe. Spend 90 minutes in the Throne Room corridor and the Grand Staircase. Arthur Evans' 1900s concrete reconstructions divide archaeologists, but they help you read the space in ways that bare ruins cannot. By 10:30, head to the Heraklion Archaeological Museum on Xanthoudidou Street, founded in 1883. The snake goddess figurines and the Phaistos Disc sit on the ground floor. Allow 2 hours. Lunch at Peskesi on Kapetan Haralampi Street. The lamb with stamnagathi, bitter wild greens that taste somewhere between dandelion and chicory, costs about 14 EUR.

After lunch, walk through Lion Square past the Morosini Fountain, carved in 1628 with four stone lions still intact. Down 25 Avgoustou Street, past the Agios Titos church rebuilt in 1869, to the Venetian harbor. The Koules Fortress at the harbor mouth costs 4 EUR and closes at 7pm in summer. The stone walls hold the afternoon heat. You can smell salt and diesel from the fishing caiques tied up inside the breakwater. Dinner at Erganos near Lion Square. The dakos salad comes on a proper dried barley rusk, crumbly and soaked in tomato juice, not the soft bread tourist places sometimes swap in. A meal for two with local Vidiano wine runs about 35 EUR. Total walking on Day 1 is roughly 6km if you taxi to and from Knossos.

Day 2 means renting a car. Local agencies near Heraklion airport tend to charge 30-45 EUR per day in June. The 140km drive west to Chania on the E75 takes about 2 hours along the north coast. Park outside the old walls near 1866 Square. Walk into the Topanas neighborhood, where the alleys narrow to shoulder-width and the stucco peels in sun-bleached strips. The Chania Municipal Market, built in 1913 in a cross-shaped plan, sells graviera cheese wheels, mountain tea bundles, and thyme honey by weight. Lunch at Tamam on Zambeliou Street, inside a converted Ottoman bathhouse from the 1600s. The goat with mizithra cheese costs about 14 EUR. In the afternoon, walk the Venetian harbor to the Egyptian Lighthouse at the breakwater's end, rebuilt in its current form around 1838. The light turns warm and gold by 6pm. Stay overnight in Chania. A double room at a small guesthouse on Zambeliou runs 70-90 EUR in June.

Day 3 leaves Chania heading east. The 60km drive to Rethymno takes about an hour. Rethymno's Fortezza sits on Paleokastro hill above the old town. The Venetians finished it around 1590 after the Ottomans attacked in 1571. Entry costs 4 EUR. The walls look out over the Cretan Sea in three directions, and the wind picks up early on the exposed ramparts. Allow an hour to walk the perimeter. Below the fortress, the old town's streets still follow the Venetian-Ottoman grid. Coffee at Galero on Plastira Square near the Rimondi Fountain, where a freddo cappuccino costs about 3.50 EUR. From Rethymno, the drive back to Heraklion covers 80km, about 90 minutes. If your flight leaves late, stop at Ammoudara beach 5km west of Heraklion. The sand is coarse and grey, not the fine white of the south coast, but the water is clean and sunbed pairs cost about 7 EUR.

Temperatures in Heraklion currently sit around 23°C in the morning and climb past 30°C by early afternoon. Sunscreen matters more than rain gear in June. Crete's tap water is safe to drink in the north-coast cities. KTEL buses connect Heraklion to Chania for about 15 EUR and 3 hours, or to Rethymno for 8 EUR and 90 minutes, if you skip the rental car. Without a car you lose the flexibility to stop between cities. The island stretches 260km east to west. Total driving across this itinerary runs about 280km. Walking adds another 15km, mostly on stone and cobbles that hold heat. One thing worth knowing about Cretan meals. They tend to end with a free plate of fruit or a small raki, called tsikoudia locally. Nobody is trying to upsell you. The tsikoudia is grape-pomace spirit, around 40% alcohol, and it is always on the house.
