Our favourite rooms
Whether it’s waking up to verdant valley views in the summer, or snow-blanketed slopes come winter, the Mountain Suites put you in prime peak-gazing position. With uninterrupted views across the Aosta Valley from their private balconies, these split-level, chalet-style suites bring the outside in – sky-high windows, lots of wood panelling, and bouclé cushions complete the Alpine-chic look.
Poolside
Swimming in the hotel’s 25-metre indoor lap pool (open daily from 8am to 8pm) can be as spritely or soothing as you like – the semi-Olympic size lends itself to some active lengths, though the soaring windows overlooking the surrounding valley might tempt you to simply soak up the heated saltwater (and snow-dusted trees stretching as far as the eye can see).
Spa
Aethos Monterosa has plenty of relaxation on tap for mountain-weary adventurers, delivering restorative rituals throughout the indoor and outdoor wellness areas. Hiked or biked a little too hard? A 40-minute reflexology session will soon have you hitting the trails again. Post-piste soreness beginning to set in? Book a 60-minute sports massage, then unwind in the wood-fired saunas and outdoor hot tubs. There’s also a hammam, relaxation room and terrace with loungers facing the mountains, and an outdoor glass-fronted spa cabin for purifying facials and couple’s massages. Nourishing berries, herbs and plants foraged from Nordic fjords and forests are bottled by all-natural Danish skincare brand Woods Copenhagen, and used in the hotel’s enriching Alpine treatment menu. In the well-equipped gym, fitness sessions and boxing lessons are available with the hotel's personal trainer, Massimiliano.
Packing tips
Thermals and cashmere bed socks will be your best friends on this Alpine adventure, closely followed by a pair of polarised sunglasses for bluebird days.

Recommended rooms
Family Suites sleep up to four, with a twin room downstairs and a king-size bedroom on the upper level (and two bathrooms – ideal if you don’t want to share with the kids). Sofa beds can also be made-up in the duplex Mountain Suites.
Crèche
The hotel runs regular ‘Kids’ Hours’ for groups of up to 10 children (between the ages of five and 10), keeping them on their toes – in an engaging way – with climbing, slacklining, juggling and more. Movie nights are hosted in the kids’ club from 7.30pm, screening age-appropriate flicks and cartoons until 9pm (burgers, fries and popcorn complete the cinema experience).
Activities
With dedicated climbing lessons for under-14s and family packages (combining under- and over-14s if siblings or parents want to climb together), everyone can make the most of the hotel’s indoor wall. Little ones need not miss out on the spa either – there are 30-minute children’s massages (for ages between six and 13) if they’re in need of some downtime.
Swimming pool
There’s no lifeguard on duty at the indoor pool, so you’ll need to keep an eye on little swimmers.
Meals
The all-day dining menu in Summit is ideal if you’d prefer flexible meal times, and there’s a kids’ menu of simple Italian classics like pesto pasta and Milanese chicken.
Babysitting
Can be arranged for €20 an hour, and must be booked in advance.
No need to pack
Outdoor equipment (ski rental, climbing gear, cycling helmets) can be hired at the hotel, but you’ll need to bring any baby essentials.
Sustainability efforts
This B-Corp-certified Alpine retreat is single-use plastic-free, and has installed energy-efficient lighting and heating, with water-saving measures in place throughout the rooms and wellness areas. Both restaurants take a hyper-local approach to ingredients, with many of the meats and cheeses coming directly from Aosta Valley itself.
