There are two reasons to hike Mount Zas…to stand on the highest point in the Cyclades and to summit the mountain where Zeus was born and raised.

According to Greek mythology, Mount Zas, also called Mount Zeus, is the place where Zeus spent his childhood. Tucked away on the slopes of the mountain is a small cave where Zeus was born. You can visit this cave as you hike to the summit.

Naxos is the largest island in the Cyclades. It feels vastly different from volcanic Santorini and windswept Mykonos. Naxos is mountainous, fertile, and covered with patches of trees, a rarity in the Cyclades. The geography, and the mythology, make Naxos one of the best spots in the Cyclades to go hiking.

If you know us, then you know that we can’t resist a good hike. And to explore the slopes where Zeus was raised, how cool is that?

The hike to the peak of Mount Zas is relatively short, but it’s also steep and strenuous in spots. In all honestly, I wouldn’t classify it as a “fun” hike, but the main reason for doing it is for the breathtaking views from the summit and for bragging rights that you stood on the highest peak in the Cyclades.

Here’s how to do it.

How to Hike Mount Zas

There are two main routes to the summit. The easiest route is from Aghia Marina. This hike is 5 km round trip with 500 meters of elevation gain.

The second route starts at Aria Spring and steadily gains elevation as you first pass the Cave of Zas (Cave of Zeus) and later summit Mount Zas. This article is about the hiking route from Aria Spring to the Cave of Zeus to the peak of Mount Zas.

Getting to the Trailhead

The hike starts at Aria Spring, also called Fontaine d’Aria on Google Maps. The closest town is Filoti. If you are driving here from Naxos City, it takes about 30 minutes.

The last section of the drive is on a narrow road that hugs the edge of a hillside. There are no guardrails here so be careful.

Driving on Naxos

The road ends right at the spring. We were the first car of the day and we parked up against the rock wall at one of the widest sections of road. Just note that there is not much room to turn your car around. This will become even more challenging once the road fills with more cars. If you get here early, like we did, consider pointing your car back down the road so it’s easier to drive away once finished the hike.

Aria Spring

A short, paved walking trail takes you to Aria Spring. This is a natural spring and I read that you can drink the water directly from the spring. This is a pretty spot and there is also a goldfish pond here.

Cave of Zeus

From Aria Spring, the trail starts to climb up the mountain. Mount Zas looms in front of you and it seems almost impossibly high from this point. You get an idea of how steep the trail will get, since it’s only 2.5 km (1.5 miles) to the summit.

Hiking Mount Zeus


At first, the path is paved with marble rocks. It’s easy walking.

Mount Zeus Trail

A short distance before reaching the Cave of Zeus, the marble path ends and a true hiking trail begins. The trail is easy to follow, but when in doubt, look for the rock cairns (stacked stones of rocks that serve as trail markers) or red blazes painted on the rocks.

From Aria Spring, it takes about 20 minutes to get to the Cave of Zeus. You can enter the cave and if you feel like exploring, I read that if you go in far enough, you can see stalactites and stalagmites. The flashlight on an iPhone is not bright enough to light the cave. You need something stronger, like a hiking headlamp or a flashlight.

Hiking to the Summit

The next section of trail is the most challenging. It’s rocky, it’s steep and at times you might even need to use your hands to do a little rock scrambling. Also, beware of the short, prickly thistle bushes. These are covered with sharp thorns and really hurt if you accidentally grab onto them. We found out the hard way.

The Gully

Looking down at the gully

About 10 minutes after you leave the Cave of Zeus, the trail will turn to the left. You’ll leave the rocky gully and hike up an easier trail.

There will be a short section where you walk on a bare, somewhat slippery rock face. Just beyond this, the view really begins to open up. From the trail, you can look out over the nearby villages and the hilly terrain of Naxos. The summit doesn’t look so far off and impossible from this point.

Hiking Naxos


Now, it’s just a hike up a giant slope of scree and boulders until you get to the summit. The trail will join that of Aghia Marina and most likely you will see more hikers at this point.

The Summit of Mount Zas

Once on top of Mount Zeus, enjoy 360° views over Naxos. You are now standing at 1003 meters (3290 feet), the highest point in the Cyclades. A concrete post marks the highest point.

About Our Experience

We did this hike in mid-April. The high temperature for the day was 15°C (60°F) so we had ideal hiking conditions. And since it was still the off-season, the trail was relatively quiet.

Tips to Have the Best Experience

During the summer months, start this hike early in the morning. There is no shade on the trail. In the summer, temperatures can soar so it’s best to finish this hike early in the day.

Bring sunscreen and lots of water. During the summer, I recommend 2 liters of water per person.

The trail was a little difficult to follow just past the Cave of Zeus. It turns to left just before you get to a wide swath of rocks and gravel in the gully. We almost missed the turn. Keep an eye out for the red blazes and the cairns. Sporadically, there will also be small metal signs with the number 2 on them.

And watch out for the prickly thistle bushes. Those suckers hurt!!

    Hello! The Agia Marina starting point is 7km with 300 meters in elevation where as the springs start (like you did) is 5km and 500m of elevation gain? If I’m reading this correctly it takes longer to do the Agia Marina route, but it’s less steep. Is the main difference in steepness the trek up to the cave (the first 20 mins?) I’m trying to decide where I want to start!

      Hello Steph. We only did the hike starting from the spring so I don’t know what the other trail is like, to be able to compare them. We picked the spring start to walk past the cave since that is an interesting sight to see on Naxos. Cheers, Julie

        Hi Julie! In the first 3 paragraphs you said this hike is 7km round trip + 300 elevation, and then under the mount Zas stats it says 5km (3miles). Do you remember which one it is? Cheers! Thanks for answering.

        1. Avatar for Julie Post

          You’re right! Thanks for picking up on that. The 5 km and 500 meters of elevation gain is correct, based on our elevation profile. Tim had gone through our GPX files at one point and I updated the stat section but didn’t realize I also stated it earlier. I’ll make the correction now. Cheers, Julie

    Hello! I will going to Naxos in September 2023 and staying in Naxos by Hotel Grotta. If I type in “Fontaine d’Aria” on my google maps will this take me to the start of the trailhead from where you started?

    On all trails, I noticed some people start at Saint Marina Holy Chapel, but I would like to do the longer version of the hike. Once we’re finished the hike, is it pretty easy to drive to the town of Filoti from where we parked?

    1. Avatar for Julie Post

      Yes, the road ends at Fontaine d’Aria on Google Maps and we parked along the roadside right there. If you start at Saint Marina Holy Chapel, you will be hiking to the summit of Mount Zas from a different starting point and won’t be following the trail that we outline in this post. From Fontaine d’Aria, it is an 8 minute drive to Filoti (about 3 km). Have a great time in Naxos! Cheers, Julie

    Just did the trip on late June 28th. 2023. Took the bus from chora in Naxos to Agia Marina and walked to the top of Zeus mountain.
    Walked the other route down to Filoti and passed the cave and the natural water source.

    Ended up with lunch in Filoti

    It is very convenient to use the public busses as long as you have the time (get the schedule at the kiosk where they sell tickets at the port of Chora or use the link naxosbusses.Com.
    You can walk both paths without having to get back the same track to you car

    Hello there! Thanks for an amazing and detailed description. Very helpful! I have a question. Are there any spots or parts of the path difficult for a person with a fear of falling/high? Thank you!!

    1. Avatar for Julie Post

      The worst part could actually be the drive on the narrow road to get to the trailhead. It’s not too bad, but it is narrow so this may bother some people. But the trail doesn’t have any drop-offs or a lot of exposure in any spots from what I can recall. Cheers, Julie

    Hi – I’m going to be on Naxos in late September and first few days of October. I wasn’t planning to get a car but I want to hike Mt. Zas. Any recommendation on how to get there and back?

    1. Avatar for Julie Post

      I don’t know much about getting around other than with a rental car. I don’t think you can get to the trailhead with public transportation, but I could be wrong. If you have a hotel booked they might be able to give you some info. Cheers, Julie

      Hi! We just hiked Mt. Zas a few days ago (on August 6, 2019). It was AMAZING–definitely do it!! The views at the top are spectacular. It’s not an easy hike, though, and we started at the church, which is the shorter hike (about 2-2.5 hours round trip). We did have a rental car to get to the trailhead. In Greece you can always arrange a taxi, so if you don’t have a car that’s what I would do. The taxi is going to have to either wait for you or come back after the hike. Our drive to the Aghia Marina church was a CRAZY 40 minutes from our villa in Plaka beach–lots of narrow roads and switchbacks. To be honest you might want to consider renting a car just for the day you plan to do the hike. The smaller the car, the better–it’s a tough, scary drive at times, and we were SO glad we took our small rental car rather than the big 7-passenger van we rented (our group was big and rented two vehicles for the trip–only 5 people in our group of 12 did the hike). I honestly don’t think the van could have gotten up those roads. Either way, don’t miss the hike! I would recommend it to anyone who visits Naxos who is in good physical shape. Also–we didn’t start early in the morning (more like 12:30pm), but that was fine because it was a windy day (August is nearly always windy there). We had no problems with heat–the wind felt great. Have fun!

        Thank you for your recommendation to rent a small vehicle for the drive to the trailhead. We will be hiking the summit end of April 2020 and there are 6 in our group. Was your thought that a van would have difficulty because the road was too narrow for 2 cars to pass each other; or that the road was too steep? Was it the entrire trip to the church windy and steep or just the last part which looks very loopy on the map? Also was the road paved?
        We are all avid hikers so the distance and terrain is not as big an issue as getting there.
        Thank you!

          The road is paved the entire way. It’s just the last section of road (a few kilometers) where it is very narrow (but it’s not too steep). In my opinion, the hardest part about having a van is parking it, since space is very limited. You can do it, just get here very early so you are one of the first vehicles. I can’t remember what time we got here, but it was probably around 8 am. Cheers, Julie

    Are hiking shoes/boots 100% necessary, or do you think athletic sneakers (running shoes) would be fine? Thank you!

    1. Avatar for Julie Post

      Athletic/running shoes are totally fine. That’s what Tyler and Kara wore. Ha ha…I wore Converse sneakers and Tim wore a pair of walking shoes/loafers. We didn’t feel like lugging 4 pair of hiking shoes to Greece for just a hike or 2. Have fun! Cheers, Julie

    Thanks for the great post – we are visiting Naxos this summer and I am trying to convince my family to take this hike, so I appreciate the detailed directions and tips to stay on the trail and reach the summit. We will be there in June, so I have a feeling we’ll need to start out early to beat the heat as you mention.

    1. Avatar for Julie Post

      It’s a cool hike. I will be writing more about Naxos in the next few weeks, so stay tuned. We also did a great walk between the villages and a short hike to Apano Kastro, which was nice too. Cheers, Julie
