Adria Alpina 663HT: flagship from Slovenia

Adria Alpina 663HT: flagship from Slovenia

Adria is working on a major upgrade of its portfolio. After the Astella and the Adora, the flagship Alpina has now been completely redesigned: a four-season caravan from the top segment. We look at model 663HT: a large caravan with many surprises.

On the outside, the Alpina is a very sleek caravan, with polyester outer cladding all around. This makes the roof, for example, more resistant to hail and the polyester base plate offers good protection against splashing dirt and stone chips while on the road.

The Alpina comes standard on alloy wheels and has new brushed aluminum striping – which gives it a luxurious look. The front is equipped with so-called wind deflectors that guide the wind and the luggage compartment lid opens over almost the full width. The storage system with luggage boxes is useful.

The rear has been redesigned, with integrated handles and a slim light strip for the LED taillights. A special feature is the heated drying cabinet on the side, useful for ski boots, for example. Because the Alpina is a real four-season caravan, so you can also go to winter sports. That is why, for example, there is a fixed waste water tank under the chassis that is both insulated and heatable.

Living, eating, sleeping

The wide door provides access to a remarkably spacious interior. At the front we see the L-shaped kitchen, with brushed stainless steel wall cladding that is easy to clean. The worktop contains a three-burner gas hob and an integrated sink with a wooden cover that can be used as a cutting board. An oven is standard on board and a microwave can be installed above the large Thetford fridge/freezer combination at an additional cost.

The spacious living lounge in the middle can accommodate at least six people and the longitudinal sofa opposite can optionally be replaced by an electrically adjustable lazy lounger. A nice detail is the rechargeable mood light that you can place anywhere in the caravan - or outside. You charge in a 'docking station' where the lamp is safely stored while on the road. Behind the living area we find a spacious bedroom with a transverse queen bed with adjustable headboards.

The bathroom can be found across the full width of the caravan.

The bathroom is located at the very back, across the full width of the caravan. With a spacious shower on one side and the toilet on the other side. With a large washbasin in between, also plenty of storage space, including behind the mirror. For the styling, Adria uses subtle wood colors, combined with light areas of color. The hollow cupboard flaps on the top cupboards are special - the hollow shape enhances the feeling of space in the Alpina. Nice details are the shelves that can be clicked onto special rails anywhere in the caravan, which we also see in the kitchen, for example.


The winter sports possibilities are emphasized on the inside by the standard Alde liquid heating, underfloor heating and a special airflow system for ventilation behind cupboards and under the benches. As a result, condensation does not have a chance anywhere and cold bridges are therefore not created anywhere. Beautiful mini spotlights are in the right places and indirect LED lighting is concealed everywhere in the caravan. You can control the operation via an app or via a touchscreen display at the entrance door. But you can also switch off the lighting from the bed, for example, with control panels on both sides - so you never get into an argument about who should turn off the light.

Conclusion Adria Alpina

The Adria Alpina is a caravan from the Champions League of the caravan world, which is also suitable for the harsh temperatures during winter sports. Remarkable is the extensive standard equipment - which also has a downside because it limits the loading capacity. But you will find them in abundance in the large caravan tractor that you need for these types of caravans.
