Moon Bay, Strunjan: The Walk Down Is Steeper Than Anyone Tells You

Slovenia | Strunjan | Slovenian Istria

I’d read that the walk down to Moon Bay was steep, and I still wasn’t quite ready for it. The cliffs here, made of layered flysch rock, run up to around 80 metres — the highest on the entire Adriatic coast — and the path down from the ridge cuts through that same crumbling rock rather than around it. It’s narrow, it’s uneven, and in a couple of places I found myself genuinely choosing footholds rather than just walking. I had proper trainers on and was still careful. I’d skip this entirely in flip-flops, and I mean that as a direct warning rather than a passing comment.

What’s waiting at the bottom earns the climb, though. The bay curves into a genuine crescent, which is where the name comes from, framed on both sides by those same towering cliffs, and the water is some of the clearest I found anywhere on this coast — a bright, almost glowing turquoise close to shore that deepened into a richer blue further out. I went in with a mask for twenty minutes and saw more down there than I expected from a beach this exposed: small fish moving between the rocks, larger shells scattered across the seabed, the kind of underwater texture that made we wish I’d budgeted more time for the swim than I had.

The shore itself is pebble and stone, no sand to speak of, and the width genuinely varies — wide in places, barely a metre across in others, depending on exactly where you’re standing along the curve. I noticed people spread out at comfortable distances from each other rather than crowded together, which suited the mood of the place; this isn’t somewhere that feels right with a big group or a speaker playing music. I also noticed, without making too much of it, that the far end of the bay had a quieter, clothing-optional crowd — a known and accepted use of this stretch rather than anything hidden, and not something that affected my own visit one way or the other.

Getting There: Park at Strunjan, Then Walk Up Before You Walk Down

I parked at the main lot by Strunjan beach, near the salt pans, which cost a couple of euros an hour through the EasyPark app — worth having installed before you arrive, since I didn’t see an obvious alternative way to pay on site. From there, the route doesn’t go straight to the bay. It goes up first, following the marked path through pine groves to the Strunjan Cross, a small monument on the ridge with one of the better views I found on this entire trip — the Gulf of Trieste spread out below, Piran’s old town visible in the distance, and on a clear day, apparently Trieste itself across the water, though the haze didn’t quite cooperate for me.

From the cross, the path down to the bay took me a little under twenty minutes, steep enough the whole way that I stopped twice just to plant my feet properly rather than rush it. By bus, regular services run from Portorož to the Strunjan stop, and from there you’re following the same signs and the same climb as anyone arriving by car.

What to Actually Bring

I want to be blunt about this part, because it matters more here than at almost anywhere else I’ve covered on this coast. There is nothing at Moon Bay. No bins, no showers, no shade structure, no kiosk. I carried in more water than I thought I’d need and was glad of it by the time I climbed back out — I’d say at least a litre and a half per person if you’re visiting in the heat of summer, and every scrap of rubbish, including fruit peels, has to come back out in your bag.

I also wouldn’t bring small children here unless they’re confident, steady walkers. The descent isn’t stroller-friendly in any sense, and I watched one family turn back partway down rather than risk it with a toddler in tow — which struck me as exactly the right call. Older kids who can manage a proper hike would likely enjoy the climb and the swim both, but this isn’t a casual family beach day.

The Rest of Strunjan, If You Want a Gentler Option

If the hike sounds like more than you want, the main Strunjan beach right by the parking lot is the easier alternative — concrete sunbathing areas, the Pinija restaurant, all the amenities Moon Bay deliberately lacks. I’d treat the two as genuinely different experiences rather than one better version of the other: Strunjan for convenience, Moon Bay for the climb and the quiet once you’re down. The wider nature reserve also includes a coastal walking route running several kilometres between Strunjan and Izola, with the bay sitting roughly at its midpoint — a good option if you want to keep walking rather than turn straight back up the way you came.

Moon Bay, in the Strunjan Nature Reserve, sits beneath flysch cliffs reaching around 80 metres, the highest on the Adriatic, reached only by a steep, unmarked descent from the Strunjan Cross. The crescent-shaped pebble shore and exceptionally clear water reward the climb, but there are genuinely no facilities of any kind, and the descent isn’t suited to small children or anyone unsteady on rough ground. A quieter stretch toward one end is used by naturists, openly and without fuss. Park at the main Strunjan lot, budget a couple of hours round trip, and bring everything you’ll need with you — there’s nothing to buy once you’re past the car park.

Park at Strunjan, climb to the cross first, then down. Wear proper shoes, not sandals. Bring more water than you think you’ll need, and carry every bit of rubbish back out.
