The Adria Adora 612DL Seine is part of the Slovenian manufacturer’s middle-ranking range, which has had a considerable redesign for the 2026 season, both inside and outside.

We had a quick preview of the new line-up’s debut, where it was joined by the updated Adria Action 391LH, at the Caravan, Camping & Motorhome Show at the NEC in February. So how does the updated tourer fare, and should it be considered if you’re looking for the best caravan to buy?

Pitch and set-up

We did look at the 2025 Adria Adora 612 DL Seine last season, and you may notice the silver sides on the Adora have remained. However, what you won’t notice on first glance are the improvements that have gone into construction for the new range. There are new composite slats on the wall frame, with PVC slats around the windows for extra strength.

Polyurethane slats have been added to the sidewalls, while the extruded polystyrene floor has been extended to 38mm thickness, again with composite slats and a polyester layer. All that should make for a much tougher body.

New designs and colours make the Seine’s interior look very welcoming

As for spec, ATC should make this 8.19m-long caravan that’s much easier to tow (you can always consider a caravan towing training course if you want to brush up on this, too). You get two external locker doors on the nearside, an external barbecue point, and alloy wheels.

There’s LED silhouette lighting running all the way across the top of the sidewall under the awning rail.

Lounge in the Adria Adora 612DL Seine

There has been quite a substantial redesign of the Adora interior this season. There’s a new upholstery colour, a warmer tone to the furniture, and, most noticeable of all, a new corrugated finish to the locker doors. These are also considerably less chunky than before (and more lightweight, which can only be a good thing for overall MTPLM in what is quite a heavy caravan.)

The lounge in the Seine
Upgrades include reinforced surrounds to the windows and sides, while the settee cushions can double-up as bolsters

The Seine is furnished with a U-shaped lounge with a shelf in the centre for snacks. This is a clip-on shelf, rather than fold-out, so you will need to find somewhere to store it when it is not in use. There is also a foldaway table (with easily enough room for four) that has its own storage slot in the sideboard to the right of the door.

The large window at the front lets in loads of light and air. At night you have ambient light behind the lockers, and a set of small spotlights you can slide around. These might be irritating for tall people, as it’s easy to knock your head on them.

Kitchen in the Adria Adora 612DL Seine

You only get three gas burners on the hob in the kitchen, but it is in-line with the sink, with a huge and well-lit workspace.

The kitchen is very well-lit and has good worktop space for food prep

You only get a combined oven and grill underneath, but there is a microwave inside one of the overhead lockers. There is a large slimline caravan fridge next to the unit.

Beds in the Adria Adora 612DL Seine

The side settee parts of the U-shaped lounge are possibly just long enough for smaller children, but you will probably want to turn them into a large double bed. This is slightly more tricky than usual to assemble, as you have to pull out two platforms and tie them together before putting the backrests in position above the newly exposed slats.

The two fixed single beds at the rear are long enough for almost any adult. Like the settees at the front, they can be raised up at the front to turn them into daybeds.

The new Adora continues with the fifth bed hidden in what looks like a line of three overhead lockers down the nearside of the rear bedroom. This bed, which was first introduced last time the Adoras were updated, drops down easily and you just need to arrange the safety net accordingly.

Washroom in the Adria Adora 612DL Seine

The end washroom in the Seine has been completely redesigned. There is now a large shower cubicle on the door side, with a full panel to house the riser, a clothes rail in the ceiling, and a large roof vent. This is accessed through concertina doors.

With the shower on that side, the toilet and its access hatch are nicely removed from anywhere you might have an awning, although it does sit in front of a large opaque window with a blind.

Storage in the Adria Adora 612DL Seine

There is easy access to the large, clear areas under the beds at the rear, which will offer some useful storage when you’re packing a caravan. The space on the nearside can be accessed from the outside, too.

It’s a bit more of a faff accessing the areas under the settees at the front – which are mostly clear – because you have to lift up the moving platforms. So it’s good that Adria has made the area on the nearside accessible from the outside as well.

The Seine's sideboard
Sideboard has useful USB sockets, and there’s a good bracket for a decent-size TV

There are two overhead lockers each side up at the front, and three more down the offside at the back (plus a bit more space within the lockers holding the fifth bed). There is a cupboard in the sideboard next to where the table goes, and another one up top, above where you would mount any TV.

The washroom includes two large cupboards – one to the right of the basin for all your shampoos, and another large one under the basin.

Alternatives to consider

The Coachman Laser 845 Xtra is a four-berth which has been revised for the 2026 season, combining quality with practicality, as well as excellent interior lighting.

Or how about the Bailey Pegasus Black Edition Bologna? It is another four-berth with a similar payload and showcases how well an L-shaped lounge can work.
