The Santorini caldera formed roughly 3,600 years ago during the Minoan eruption, one of the largest volcanic events in recorded history. Today that same volcanic landscape is walkable — and doable with children. When my husband Julien and I took Sofia, our six-year-old, to Nea Kameni, she managed the whole loop without complaint, more interested in the steaming fumaroles than the caldera views.
Yes, with preparation. The Nea Kameni hike is 2.5 km round trip with 130 metres of elevation gain on loose volcanic rock. It takes 60–90 minutes. There is no shade and no water on the island. Bring closed-toe shoes, at least one litre of water per person, and sun protection. The payoff is standing on warm ground near active sulphur vents with views across the entire caldera.
Walking on the youngest land in the eastern Mediterranean
Nea Kameni rises roughly 130 metres above sea level at the centre of the caldera. A 20-minute boat ride from Fira’s old port deposits you on barren volcanic ground that barely supports vegetation. The trail is a loop of rocky volcanic stone and loose pumice — nothing technical, but the unstable surface demands attention underfoot. Sofia called it “the moon place” and picked up a piece of yellow sulphur deposit near a vent.
The crater rim rewards the climb with a view across the caldera to Fira and Oia. Steam vents hiss softly from cracks in the black rock, and the air carries a faint sulfurous smell. The ground near the fumaroles is warm to the touch. Entry to the island costs Discover Greece notes the €5 fee per person, which is often not included in advertised tour prices.
Getting to the trailhead with a family in tow
Fira’s old port is the departure point for Nea Kameni boats. You have three ways down: the cable car (€6 one-way, with queues that can run 30–45 minutes in summer), the 587 steep steps (15–20 minutes down, longer coming back up), or a donkey ride. We took the cable car down and the steps back up — Sofia counted the steps until she lost interest around 200.
Boat tours to Nea Kameni typically run 25–50 € per person for guided trips that include the hike and a stop at the hot springs off Palea Kameni. The standard schedule runs roughly 09:00 hotel pickup, 10:00 boat departure, 10:20 hike start, 11:30 return boat, then a swim at the hot springs before heading back to Fira around 13:00. If you want to explore independently, you can look into half-day tour options that bundle the volcano with other stops.

The cable car can get backed up after cruise ship arrivals. If you’re on a tight schedule, consider walking down the steps in the morning when the queue is shorter. The steps are steep but well-maintained, and there are rest points with views.
What to pack for the volcano hike
No shade, no water, no facilities on Nea Kameni. Everything you need goes in your bag before you leave Fira. Here is what worked for us:
Closed-toe shoes with good grip are non-negotiable — the volcanic scree shifts underfoot and sandals are a bad idea. Trekking poles help on the descent. Each person needs at least one litre of water; we carried two for the three of us plus extra snacks. Sun protection includes a wide-brimmed hat, high-SPF sunscreen, and sunglasses. A windproof jacket is useful even on warm days because the exposed ridge can be breezy. If you plan to swim at the hot springs after the hike, pack dark swimwear — the sulphur stains light fabrics permanently.
The hot springs off Palea Kameni are warm but not hot — roughly 30–35°C depending on the mixing with sea water. The bottom is rocky and uneven. Water shoes make the experience much more comfortable for children.
Comparing family hike options on Santorini
Nea Kameni is the most accessible volcano experience, but Santorini offers other trails that families can tackle. The table below lines up the key options so you can decide what fits your group.
| Trail | Distance | Duration | Difficulty | Family notes |
|---|---|---|---|---|
| Nea Kameni Volcano | 2.5 km loop | 60–90 min | Easy to moderate | No shade; ages 5+ with sturdy shoes; €5 entry fee |
| Fira to Oia Caldera Trail | 10 km one-way | 3–5 hours | Moderate | Paved and rocky sections; best in spring/autumn; free |
| Skaros Rock (Imerovigli) | 2 km round trip | 45–60 min | Moderate to challenging | Steep sections; requires sturdy footwear; free |
The Fira–Oia trail is spectacular but long for young legs — Sofia would have needed a carrier for part of it. Skaros Rock is shorter but steeper. Nea Kameni hits a sweet spot for families: short enough to hold a child’s attention, rough enough to feel like a real hike, and capped by a genuinely unusual destination.
Beyond the volcano: building a full day
Most Nea Kameni tours include a swim at the hot springs off Palea Kameni. The water is cloudy and warm, and the bottom is rocky — water shoes help. The sulphur smell is strong, but Sofia thought it was hilarious and insisted on calling it “the egg bath.” After the boat returns to Fira, you can grab lunch at one of the tavernas near the old port or take the cable car back up to the main town for a wider selection.
Families who want more time on the water can look into catamaran cruises that circle the caldera and stop at multiple swimming spots. If the volcano hike is the main draw but you want a private pace, private sightseeing tours can tailor the schedule to your family’s rhythm. For a completely different angle, cooking classes in Fira or Oia give kids a hands-on break from the outdoors.
July and August bring intense heat and crowds to Nea Kameni. The trail has zero shade and the black rock absorbs heat. May–June and September–October are more comfortable for families. Winter services are limited and weather-dependent.
Planning your visit
Spring (April to May) and early autumn (September to October) are the sweet spots for the volcano hike. Temperatures typically range from 15°C to 30°C. Summer is hot and crowded; winter is cooler and wetter, with fewer boat departures to Nea Kameni. No permits are needed for the caldera trail itself, but the €5 Nea Kameni entry fee is collected on the island. Public buses run frequently between Fira and other villages, and Fira is reachable by bus from the airport and main ports. For more on the island’s layout and accommodation options, see the full Santorini destination guide.
Is the Nea Kameni hike safe for a six-year-old?
Yes, with supervision. The trail is rocky and uneven, and the ground near fumaroles can be unstable and warm. Keep children on the marked path and watch for loose scree. The hike is rated easy to moderate and many families with children aged five and up do it.
What is the total cost for a family of three?
Boat tours range from 25–50 € per person, which usually includes the boat ride and the €5 island entry fee. The cable car costs 6 € per person one-way. Budget roughly 100–170 € for the full morning including transport, the hike, and the hot springs stop.
Can we skip the hot springs swim?
Yes. Most tours offer the option to stay on the boat during the hot springs stop. The water is warm but cloudy, and the sulphur smell is strong. Some children love it; others find it unpleasant. Pack a towel and a change of clothes regardless.
What happens if the weather turns bad?
Boat tours to Nea Kameni are weather-dependent. Strong winds or rough seas can cancel departures. Check the forecast the day before and have a backup plan — the Fira–Oia caldera trail is a good alternative on clear days even if the boat isn’t running.
How long does the whole morning take?
A typical tour runs from 09:00 to 13:00, including hotel pickup, the boat ride, the hike, the hot springs swim, and return to Fira. The hike itself is 60–90 minutes. The boat ride is 20 minutes each way. Plan for half a day.
The Santorini volcano hike works because it asks just enough of a family without demanding too much. A short boat ride, a manageable climb, and a destination that genuinely surprises — warm ground, hissing steam, and a view that explains why people have been living on this caldera for thousands of years.
