We spent three nights at Hotel Castillan. It was the only hotel with rooms available when I booked and as it was only 2 stars, I was a little apprehensive. However, on arrival we found It has just about the best views in La Grave across the valley to La Meije and its glacier. Ourr 2nd floor room was not enormous but sufficient, with an interesting take on en-suite, with the bath in one alcove and the basin and loo in another. But, it was clean and comfortable and the view from the balcony was amazing.
The hotel staff could not have been more friendly or helpful. The buffet breakfast was fine - we had fresh croissants and coffee each morning - and we ate in the hotel restaurant each evening, where the food was wonderful - local Savoyan specilaties were especially good, and the chocolate fondant to die for!
We spent one day walking the Sentier du Facteur - a walk from the hotel up through the hills to a smaller village in the next valley - more amazing views, flowers and birds. and the second driving up to the Col du Lauteret and its Alpine Garden and on to the Col du Galibier.
We thoroughly enjoyed our stay here and would recommend this hotel to anyone wishing to visit La Grave.
