Porto Cristo has two show caves, roughly two kilometres apart, both with an underground lake, both with a classical music performance, both open year-round. Visitors routinely assume they’re the same place, or that one ticket covers both, or that they’re near-identical and there’s no point doing both.
None of that is right. They’re separately owned, separately ticketed, and genuinely different experiences — and one difference in particular catches people out.
The single most important distinction: At the Caves of Drach you ride a boat across Lake Martel. At the Coves dels Hams you watch a boat glide past on the Sea of Venice. Visitors who book Hams expecting the boat ride they saw in photos are frequently disappointed. Know this before you choose.
The Short Answer
Visit the Caves of Drach if you want the headline spectacle: a much larger cave system, one of the world’s largest underground lakes, a live classical quartet performing from illuminated boats, and a boat ride across the water yourself. Accept that you’ll share it with a very large crowd.
Visit the Coves dels Hams if you want a guided, small-group visit with actual commentary, a rare and genuinely unusual geological feature, and a more intimate candlelit finale. Accept a smaller cave and no boat ride.
Visit both if you have half a day. They’re five to ten minutes apart and the experiences complement each other more than they duplicate.
Other Cave and East Coast Experiences in Mallorca Worth Knowing About
Coves dels Hams and the Caves of Drach are both in Porto Cristo on Mallorca’s east coast — a region that also includes Coves d’Artà to the north, Dinosaurland next to Hams, and boat excursions along the coast. Below are other tours and experiences in this area that visitors often find worth knowing about.

What Makes the Coves dels Hams Distinctive
The fishhooks — and the geology behind them
“Hams” means fishhooks in Mallorquí. The name refers to the cave’s abundance of helictites — and this is the most genuinely interesting thing about the site, usually reduced by other guides to “scientists can’t explain them.”
Here’s the actual explanation. An ordinary stalactite forms as mineral-rich water droplets hang from the ceiling and gravity pulls them straight down; calcite deposits build a straight, vertical spike. Helictites ignore that. They twist, curl, branch sideways and even grow upward, in shapes that look as though they formed in zero gravity.
The mechanism is capillary action. Water travels through a hair-thin central canal inside the formation rather than dripping down its outside. At that microscopic scale, capillary force is stronger than gravity — so the water reaches the tip and deposits calcite regardless of which way the tip happens to be pointing. The formation wanders.
The precise controls on their direction are still debated. What’s not debated is that helictites are rare, and that Hams has an unusual concentration of them — particularly in the chamber known as An Angel’s Dream. If you have any interest in geology, this is the reason to choose Hams. Drach has more stalactites and a vastly bigger lake, but nothing like this.
Discovered in 1905, family-owned to this day
The caves were found on 2 March 1905 by Pere Caldentey, a Manacor man quarrying for onyx. Rather than mine the formations away, he developed the site as a show cave and opened it in 1910 — predating the Caves of Drach’s 1922 opening by over a decade. He electrified it using a water-mill-driven dynamo, remarkable given that Porto Cristo itself had no public electricity at the time. The caves remain family-owned today.
What a visit involves
The route runs through three distinct parts:
- The Round Cave — a collapsed, open-roofed chamber now planted as a botanical garden of native Mallorcan species, with free-flying native birds.
- The Blue Cave — a seated chamber with a documentary on Mallorca’s history and the cave’s formation, plus a projected sequence in a natural auditorium.
- The Classic Cave — the original 1905 system of twelve galleries, where the hook formations are, ending at the Sea of Venice.
The finale, “Magical Mozart,” takes place in near-darkness on the lake: candlelight and projections play across the walls while an illuminated boat crosses the water. You watch from tiered seating. Book Coves dels Hams →
What Makes the Caves of Drach Distinctive
Scale
Drach is simply much bigger — roughly 1,200 metres of walking route through four connected chambers, descending around 25 metres. Lake Martel is the centrepiece: over 100 metres long, slightly saline through a subterranean connection to the Mediterranean, and almost perfectly still, mirroring the stalactites above it.
The concert, and the boat
A quartet — two violins, cello, and a keyboard instrument — performs from illuminated boats on the lake, a tradition running since 1935. The concert lasts around ten minutes and is followed by a lighting sequence that simulates sunrise on the water (“Dawn on the Lake”).
Afterwards you cross the lake: by boat, or on foot over a bridge, both included in your ticket at no extra cost. The boat queue can be long in peak season, which is the only real reason to take the bridge.
The trade-off
Drach receives well over a million visitors a year. The concert auditorium seats around a thousand, and in high season it fills. The walk is not guided — you move in a large group with staff directing flow but no commentary.

Which Should You Choose?
Choose Drach if you…
- Only have time for one cave and want the famous one
- Want to ride a boat on an underground lake
- Want live classical music in a spectacular setting
- Are travelling with someone who’d find a small cave underwhelming
Choose Hams if you…
- Want a guide who actually explains what you’re looking at
- Have any interest in geology — the helictites are genuinely worth it
- Dislike large crowds and prefer a smaller-scale experience
- Are travelling with young children and want to add Dinosaurland
Choose both if you…
- Have half a day and a car
- Want to understand Mallorcan cave geology properly rather than just see a spectacle
Doing Both in One Day
Entirely practical. They’re a five-to-ten-minute drive apart on the same road out of Porto Cristo, both with free parking.
Recommended order: Drach first, Hams second. Taking the earliest Drach session gets you in ahead of the coach parties, which matters far more at Drach than at Hams. And seeing the smaller cave second works better than you’d expect — Hams’s guided commentary gives you the geological context that Drach’s silent walk doesn’t, and you’ll re-interpret what you saw at Drach with fresh understanding.
A workable half-day:
- Morning — first Drach session of the day (10:00 in summer)
- Late morning — drive to Hams, take a mid-morning tour
- Lunch — Porto Cristo harbour, once the coaches have descended on the caves
- Afternoon — the beach, or the coast road south
Pre-book both. Neither operator sells a joint ticket, so these are two separate purchases. For a hassle-free combined day — transport, timed entry at both caves, and a guide — a bundled excursion covers everything: Check availability & prices →
Dinosaurland: The Family Factor
Immediately next to the Coves dels Hams, under the same ownership, sits Dinosaurland — an open-air park with over a hundred life-size dinosaur models, an excavation area for children, and a themed restaurant. A combined ticket covers both the caves and the park, and it’s the single strongest argument for choosing Hams over Drach if you’re travelling with primary-school-age children. Allow about an hour for the park on top of the cave visit.
How These Two Compare to Mallorca’s Other Caves
Porto Cristo isn’t the only cave destination on the island:
- Coves d’Artà (Canyamel, north-east) — arguably the most dramatic cave on Mallorca. A cliff-top entrance above the sea, enormous chambers, and one of Europe’s largest stalagmites. Guided, with a light-and-sound sequence — but no lake, no concert, no boat. Many independent visitors rate it above both Porto Cristo caves for sheer grandeur.
- Coves de Campanet (near Sa Pobla) — small, quiet, genuinely uncrowded, with delicate formations and endemic cave fauna. The choice if you want tranquillity over spectacle.
- Cuevas de Génova (near Palma) — the smallest and least commercial, with personalised short tours. Convenient if you’re based in Palma and don’t want to cross the island.
Frequently Asked Questions
Is there a combined ticket for Caves of Drach and Coves dels Hams?
No. The two are separately owned and separately ticketed. Some coach excursions visit both, but you cannot buy joint entry directly from either operator. A combined Hams + Dinosaurland ticket is available at the Hams ticket office.
Do you go on a boat at the Coves dels Hams?
No. You watch an illuminated boat cross the Sea of Venice from seating at the lakeside. The boat ride you may have seen in photographs is at the Caves of Drach. This is the most common point of confusion between the two caves.
Which cave is bigger, Drach or Hams?
Drach, substantially. Its visitor route runs roughly 1,200 metres through four connected caves; Hams’s route is around 500 metres through twelve galleries.
Are the Coves dels Hams guided?
Yes — in small groups with multilingual commentary. The Caves of Drach are not guided; you walk in a large group with staff stationed along the route but no narration. This is the second biggest practical difference between the two.
Which is better for children?
Hams has the edge if you add Dinosaurland next door. Drach has the boat ride, which younger children usually love. Neither allows prams inside, and both involve steps.
Which is better for someone with limited mobility?
Drach handles it somewhat better in terms of path management, though both caves involve substantial flights of steps and neither is genuinely wheelchair accessible. Neither allows prams inside the cave.
How far apart are the two caves?
About two kilometres — five to ten minutes by car — both just outside Porto Cristo on the Manacor road, both with free parking.
Is it worth visiting both caves?
Yes, if you have half a day. They’re different enough to justify it — different scale, different geology, different show format, and Hams gives you the guided explanation Drach lacks. If you only have time for one, choose Drach.
Which is cheaper?
Hams is generally slightly cheaper for standard adult entry, and both offer reduced child rates with free entry for infants. Both are cheaper booked online than at the gate. Prices change — check current rates before travelling.
What are helictites and why does it matter that Hams has them?
Helictites are cave formations that grow sideways, upward, or in curves rather than straight down — shaped by capillary forces rather than gravity. They are geologically rare and look unlike anything you’ll see at most show caves. Hams has an unusually high concentration, making it the more interesting site from a geology perspective, despite its smaller overall scale.
