The short answer
Both are large eastern Aegean islands sitting a narrow strait off the Turkish coast, both are driving islands, and both stay quiet because neither is on the package map the way Kos and Rhodes are. What they offer is different. Samos is green and mountainous, with hiking, springs, vineyards and sweet wine, plus ancient Ephesus reachable across the water. Chios grows the only commercially harvested mastic on earth in a set of fortified medieval villages, and holds an eleventh-century monastery with gold-ground mosaics on the UNESCO list.
Choose Samos for mountains, walking, wine, and a day in Ephesus. Choose Chios for the mastic villages, Nea Moni, and something no other island has. Do both with a fortnight, or pick one and give it four unhurried days.

Samos is the green mountain island
Samos lies in the north-eastern Aegean, one of the closest Greek islands to the Turkish mainland, with the strait narrowing to the point where the far shore is part of the view from the east coast. It is not the bare, whitewashed Cyclades most first-timers picture.
The greenness is geography rather than decoration. Two ranges fill the island, Mount Kerkis in the west and the Ampelos range through the centre, and the high ground catches passing weather, so the upper slopes hold pine forest, springs and seasonal waterfalls while the terraces below grow vines. The result feels closer to a corner of the mainland set adrift than to a Cycladic postcard.
Four places orient it: Vathy, also called Samos Town, the capital and main port in the north-east; Pythagorio on the south coast near the airport and the ancient sites; Karlovasi anchoring the west; and Kokkari on the north coast. They sit far enough apart that where you arrive shapes your first day.
This is an island for hiking, villages and wine rather than a flat strip of beach bars.
Chios is the mastic island, and nowhere else is
Chios is a big working island whose central claim is singular: the fortified villages of its green south grow the only mastic commercially harvested anywhere on earth. Add the gold-ground mosaics of Nea Moni, an eleventh-century monastery on the UNESCO World Heritage list, and you have the two things Chios is for.
The south is the green half, low hills of mastic groves and citrus where the medieval mastic villages cluster. Closer to Chios Town, the Kampos district holds walled estates, each a mansion behind a high wall with its own citrus orchard, cistern and monumental gate, a plan the Genoese laid down and the Ottomans left largely intact. The north is rougher, more mountainous, emptier and slower to cross.
That combination is genuinely unlike anywhere else in Greece, and it is the reason to pick Chios over its neighbour.
Both are driving islands, and Chios more so
Chios is large, its draws are scattered across the south and interior, and its one real town sits on the east coast. You cannot see it on foot or from a single base, and the distances between the villages, the monastery and the good beaches are exactly why a car matters.
Samos has the same problem in a gentler form: four widely separated anchor points and mountain roads between them.
Neither is an island to visit without wheels. Renting a car in Greece and which islands need a car cover the practicalities.
Crossing to Turkey
Both sit a short strait from the Turkish coast and both have a crossing, which is unusual and worth planning around.
From Samos, ancient Ephesus is reachable across the water in a morning, and it is one of the great classical sites of the Mediterranean. That is a strong reason to choose Samos if you have not seen it.
From Chios the crossing lands at Cesme, which is a pleasant town rather than a major site. Useful, but not the same draw.
Check visas and entry requirements before counting on either, because leaving and re-entering the Schengen area is the part people forget.
Walking and wine
Samos takes both. The mountain village trails are the island’s best feature after the ancient sites, and the sweet muscat tradition is real rather than a gift-shop line. If a holiday of walking in the morning and tasting in the afternoon appeals, Samos is the answer.
Chios walks less well: it is a driving island, and the pleasure is architectural rather than topographic.
Beaches
Close, and neither is a beach destination. Samos has decent beaches around its north-coast villages, Kokkari especially. Chios has quiet coves spread far apart, which means a drive for each one.
If sand is the point of the trip, both of these are the wrong island, and the honest alternatives are in the Cyclades or the Dodecanese.
Who each suits
Samos suits walkers, wine drinkers, anyone who wants to see Ephesus, travellers who like green mountain landscapes, and people staying five nights or more.
Chios suits travellers who want somewhere genuinely singular, anyone interested in architecture and craft, drivers, and people who would rather tour than sunbathe.
Neither suits a first Greek island, a package beach week, or anyone without a car.

Doing both
They are neighbours in the same sea and pairing them works with a fortnight, though the connection is not as frequent as a Cyclades hop. Athens to Samos and Athens to Chios cover getting out; the north Aegean line links the two islands directly, less often than a Cyclades hop. The group is in the north Aegean islands.
With a week, take one. Samos if you want to move and walk, Chios if you want to look at things nobody else has.
Where this leaves you
Samos is the greener, more mountainous island: hiking, springs, vineyards, deep antiquity and Ephesus a morning away. Chios is the stranger and more particular one: fortified villages growing the world’s only mastic, walled Genoese estates, and a Byzantine monastery with mosaics worth the trip on their own. Both need a car and several unhurried days. Choose on whether you would rather walk a mountain or drive to something unrepeatable.
Quick answers
Which is better for hiking, Samos or Chios?
Samos. Two mountain ranges fill the island, the upper slopes hold pine forest and springs, and the village trails are one of the main reasons to come. Chios is a driving island where the pleasures are architectural rather than topographic.
What is mastic, and why does it matter on Chios?
Mastic is a resin harvested from trees that grow commercially nowhere else on earth, and the fortified medieval villages of the green south of Chios exist because of it. It is the island’s defining feature and the reason to choose it over any of its neighbours.
Can you visit Ephesus from Samos?
Yes. Samos sits a narrow strait from the Turkish coast and Ephesus is reachable across the water in a morning, which is a genuine reason to pick the island. Check the entry rules before relying on it, since leaving and re-entering the Schengen area is the part travellers overlook.
Do you need a car on Chios?
Yes, emphatically. It is one of the larger Greek islands, its mastic villages, monastery and beaches are scattered across the south and interior, and it has one real town on the east coast. It cannot be seen on foot or from a single base.
