1. Never Bay – One of the Wildest Hidden Beaches on Ios
When it comes to Ios hidden beaches, Never Bay tops the list. Located near the southern tip of the island, it’s famous for both its beauty and its adventurous journey.
The best route is to take an ATV from Manganari Beach along the rugged coastal path. From there, you’ll need to descend a steep, rocky trail on foot. The walk is tricky and not recommended in sandals, but once you reach the bay, you’ll be rewarded with a wild, untouched inlet framed by dramatic cliffs and impossibly blue water.
This is Ios at its rawest—perfect for travelers searching for adventure and seclusion in 2026.
2. Koumbara Caves – Ios’s Mermaid Playground
If you’re compiling a list of unique things to do in Ios, Greece, the Koumbara Caves deserve a spot. Tucked away near Koumbara Beach, just a short drive from Chora, these caves feel like nature’s secret swimming pools.
To find them, head to the far end of Koumbara Beach near the small peninsula leading toward Billionaire Island. From here, you’ll see rugged cliffs concealing entrances to the caves. Locals love to slip inside and float in the crystal-clear water while gazing out at the Aegean.
It’s quiet, enchanting, and feels worlds away from the busy beach clubs.
3. Flat Rock – An Ios Classic
For those chasing Ios sunsets or searching for the island’s most photogenic swim spot, Flat Rock is an essential stop. This natural stone platform juts dramatically into the Aegean and is perfect for both diving and sunbathing. Getting there is an adventure in itself, but one that’s completely worth the effort.
Here’s how to reach Flat Rock:
- Drive or walk to the very end of Mylopotas Road until it turns into a dirt path leading up the mountain.
- On your right, you’ll see a signpost marking the start of the trail.
- Begin climbing by following the red paint dots on the rocks.
- Midway, sea views begin to open up. Once you reach the top and the trail looks like it starts descending again, stop following the red dots—they lead to other routes.
- Instead, climb over a few low rock walls until you spot a lone tree ahead. This tree is your landmark.
- Pass the tree, then begin your descent, keeping an eye out for a trail that clearly looks like it’s been walked before.
- Follow this path and soon you’ll discover a massive, flat rock overlooking the sea—your destination.
It’s a raw, cinematic spot for cliff diving, sunbathing, or simply watching the sky turn golden as the sun sets.

4. The Secret Gypsy Cove – A Hidden Gem
If you’re looking for a hidden cove in Ios, this is the one.
The locals call it ‘Katsiveki Cove’, another way of saying Gypsy, but the Harmony crew likes to call it ‘The Secret Cove’ — a pebble-strewn hideaway tucked beneath a hillside villa on the other side of Kolitsani Beach. In summer, yachts often anchor here for a quiet escape, but from shore, it remains hidden unless you know exactly where to look.
How to get there:
- Enter Thalassa Villa into Google Maps.
- From the villa, walk down the hilly road until you see a sign for ‘Kolitsani Nude Beach’.
- Ignore the sign pointing right and instead take the left path, marked by red-painted stone steps.
- Follow the descent until you spot a boat moored at the pebble shore—you’ve found it.
It’s one of the most secret Ios coves, perfect for a romantic swim or just escaping the crowds whilst feeling like you’re part of the Mamma Mia movie.
5. Ios Lighthouse – A Panoramic Escape
Not every must-see on Ios is a beach. For a change of pace, rent an ATV or bike and head north to the Ios Lighthouse, perched on the edge of the island.
From Chora, the drive takes about 25 minutes, followed by a short walk to the lighthouse. Here, you’ll be greeted with sweeping views of the Aegean, the kind that makes you pause and just breathe it all in. On clear days, you can even spot neighboring islands.
It’s one of the best non-beach things to do in Ios—especially at sunset.
6. Valmas Beach – The Secret Gulf Near Chora
Another Ios hidden gem is Valmas Beach, a tranquil sandy cove that feels far removed from the busier shores. Surprisingly, it’s just a 15–20 minute walk from Ios Port.
Here’s how:
- Start at Agia Irini Church, overlooking the port.
- Enter through the black gates and head to the back of the church.
- Look for red paint markings on the rocks—these guide you along the flat cliffside trail.
- After 15 minutes, the path descends toward the beach.
What makes Valmas truly special is its atmosphere. A deserted taverna sits perched above, silent but full of character. Swimming here feels cinematic, like stepping into your own Mamma Mia moment.
If you’d rather not walk, put On the Rocks Villa into Google Maps, drive there on an ATV or bike, and finish the final descent on foot.
7. Diaseli Ios Traditional Cheesery – Local Flavors in the Hills
No Ios travel guide is complete without a taste of local culture. For that, head into the hills above Chora to the Diaseli Traditional Cheesery & Folklore Museum. Founded in 1922, this family-run gem offers a glimpse into Ios’s agricultural past.
Visitors can explore an 18th-century stone home, a threshing floor, and original cheesemaking tools that have been preserved through generations. The real highlight comes at the end: a tasting of eight handcrafted cheeses paired with local honey, olive oil, and bread from a traditional oven (Diaseli official site).
