Fifteen days out that survive the toughest audience in the house. Water, heights, screen-famous sets and an underground river — and three of them cost nothing at all.
The range — a floating aqua park, treetop zip lines, a cliff path riveted over the Atlantic, the actual Game of Thrones sound stages, a Victorian prison and a river you ride under a mountain. Whatever your teenager is into, something here lands.
Cost — the Cuilcagh climb, the Derry Girls mural and the Dark Hedges are free; the paid ones start around £12.50. Every entry links to our full guide with current prices, hours and parking.
Most of the big hitters are pre-booked, timed sessions — and the best carry age and height gates: Hydro is 7+ and 110cm, the Gobbins is 1.2m, Oakfire's ropes are 10+. For this crowd that's the point — it proves it's not a kiddie ride.
The photo moment — the Cuilcagh summit steps, the Dark Hedges avenue, the mural, the throne. Phones out is the plan here, not the problem.
When — Hydro and the heights are warm-weather plans; the Studio Tour, Titanic, the Gaol, W5 and Infinity are all indoors and rescue a wet Saturday without a fight.

Let's Go Hydro
Carryduff, near Belfast · Sessions from around £25
The pitch sells itself: Ireland's biggest inflatable aqua park, floating on a lake just south of Belfast, and 50 minutes to throw yourself around it. Climbing walls, a slide tower, trampolines and monkey bars, all bobbing on the water — falling in is the whole point, and the wetsuit and buoyancy aid come with the session. The entry rules do the convincing: you have to be 7+, at least 110cm, and able to swim 50m unassisted. That's not small print. That's the appeal.

Not a themed exhibition — the actual sound stages where much of the series was shot, out at Banbridge. Walk into the Great Hall of Winterfell and onto Dragonstone, stand in front of the throne itself, and get close to thousands of the real costumes, weapons and creatures, with the behind-the-scenes story of how it was all made. Most visits run 2–3 hours, it's one of the biggest indoor attractions on the island, and even the teenager who's only seen the memes comes out quietly impressed.

Islandmagee, near Larne · £23.50 adult, £17.50 child
A mile of steel bridges and railed walkways bolted to a sheer sea cliff, a tunnel bored through the headland, and the Atlantic crashing right under your feet. The guided walk runs about 2.5–3 hours and roughly 3 miles, climbing and dropping the equal of 50 flights of steps — a physical thing you do, not a view you're marched past. Puffins nest here in early summer. The requirements are the recruitment poster: 4ft (1.2m) minimum, proper walking boots, no trainers. Every walk is guided and pre-booked, and slots sell out.

The glen itself is a free wooded river valley under Black Mountain. The reason a teenager gets out of the car is bolted to the hillside above it: zip lines flying out over the valley and the Black Bull Run alpine coaster racing down through the trees, backed up by high ropes and a climbing wall. The rides run in timed sessions booked online, and each carries its own minimum age and height, so check who can go on what before you set off. The six miles of woodland paths make a decent cooldown lap.

A single-file rope bridge said to hang almost 100ft above the Atlantic, slung across a chasm to a tiny rocky island. The sway is real, the drop is very real, and crossing it is a story that outlives the day — with a clifftop walk out that throws in views to Rathlin and, on a clear day, Scotland. Allow about an hour and a half for the walk, the wobble and the island. Timed tickets only — even National Trust members need a slot — and it closes in high winds with a full refund, so check the day's status before you go.

Florencecourt, Co. Fermanagh · Free walk, £6 car park
They've seen the photo. The pale boardwalk running dead straight across wild blanket bog, then the famous timber staircase — the "Stairway to Heaven" — climbing into the sky. The summit shot is earned, not handed over: 3 to 4 hours and roughly 13km there and back, with about 450 steps in the final push and one of the finest views in Fermanagh waiting at the platform. It's the free entry on this list that feels like an achievement. Boots, waterproofs and your own water — there's no shelter and no toilets out on the trail.

Pick the mission: the Zip Trek, a run of zip lines over woodland, water and cliff; the Tree Trek high-ropes and via-ferrata course through the trees; the combined Full Aerial Challenge; or paintball in the woods for the older ones. Sessions run 1 to 3 hours depending on which you choose, and it's active, on-your-feet stuff the whole way. The gates flatter this age group nicely — aerial courses are 10+ and about 1.4m minimum, paintball is 16+. Booked sessions only, so reserve a slot before you travel.

An indoor arena built for burning off exactly this age group: wall-tramps, trampoline dodgeball and basketball dunk zones, a ninja obstacle course with hanging rings and a battle beam, foam pits and a giant air bag to leap into. Sessions run on the hour and it's priced per hour, so one intense hour is a legitimate plan — most do two. Grip socks are required at £2 a pair, everyone jumping needs a waiver signed online, and it's closed Mondays. The venue says it suits ages 1 to 104; the dunk zones say otherwise.

Nine galleries built on the actual slipways where the ship was built and launched, inside a silver building that rises 126 feet — said to match the height of Titanic's hull. This is the story they half-know from the film told properly: the shipyard, the launch, the sinking, the discovery of the wreck. You ride through the shipyard recreation in a six-seater car, and the ticket includes the SS Nomadic at the dock, described as the last surviving White Star Line ship. A solid 2–3 hours, all indoors, and the building alone is worth the photo.

A real Victorian prison you walk straight through: the great C-wing with its three tiers of iron landings, the tunnel that runs under the Crumlin Road to the old courthouse, the holding cells and the condemned cell. The everyday visit is self-guided, 60 to 90 minutes with audio and video carrying the story room by room. The history here includes imprisonment and executions carried out within the walls, told honestly and with care — which is exactly why this age group rates it. All indoors, so save it for the grey day.

The Portrush amusement park every Derry Girls fan will clock on sight — the Big Dipper and the ghost train are both in the show. This is the old Barry's, and it still works the old way: walk in free, buy tokens, pick your rides. The taxi dodgems, the waltzer, a 40-metre swing tower, and a big loud arcade of 2p pushers and grabbers that swallows an hour whenever the sea decides to rain on you. It runs roughly Easter to early September from around noon — set a token budget before anyone touches the dodgems.

A guided walk deep under Fermanagh through one of the finest show-cave systems in Ireland — floodlit chambers of stalactites, black pools so still they mirror the roof, and when the water's right, a boat glide along an underground river. Riding a boat under a mountain is a hard thing to be unimpressed by. Tours run about an hour to 75 minutes underground, it's a steady 9–10°C down there whatever summer is doing, and there are around 154 steps — bring a coat and shoes with grip. Pre-booked guided tours only.

Erin, Orla, Clare, Michelle and James — the English one — painted two storeys high on the gable of Badgers Bar, the most-photographed wall in the city. The photo takes five minutes and costs nothing; the point is what's around it. You're standing in the actual city the show is set in: the city walls are a two-minute walk, the Bogside murals are just up the hill, and a Derry Girls walking tour covers the real filming spots. The wall sits on a busy road, so grab the shot and mind the traffic.

The Kingsroad. An avenue of old beech trees that lean in and knit overhead into a green tunnel — the stretch that stood in for it in Game of Thrones, and one of the most photographed spots in Northern Ireland. It's a 20–40 minute stop, not a day out, and that's its job: the dramatic photo on the way to or from the coast. Two honest notes from our guide — storms have thinned the trees since the postcard shots, and the middle of the day is crowded. Go at golden hour: warmer light, emptier road. The avenue is closed to cars, so park at the nearby hotel and walk in.

Belfast's science centre reads younger on paper and lands harder in person. There are 250-plus hands-on exhibits across themed floors — MED-Lab, Energise, optical illusions, nothing behind glass — plus live science shows with a bang. The teen magnet is Climbit: an abstract steel climbing sculpture rising through the middle of the building, a three-dimensional maze you scramble up and through while everyone below watches. From £12.50 adult, comfortably a half day, and all indoors. Book a timed slot; Climbit can carry its own height and age rules and may cost extra.

The Belfast one: Titanic Belfast on a booked slot, then W5 a short walk away — a full day, all indoors, zero weather risk.
The coast one: Carrick-a-Rede first thing on a timed ticket, the Dark Hedges on the road, then Curry's tokens in Portrush to finish.
The Fermanagh one: climb Cuilcagh in the morning, then Marble Arch Caves — the summit steps and an underground river in a single day, both at Florencecourt.
