Lenzerheide is not known for its nightlife, the whole area is made up of a string of villages, neither of which is really the size to really get much of a scene, and Churwalden is the quietest of them all. Hotel Krone (www.krone-churwalden.ch) has the only bar of note and usually stays open late. It’s still very quiet but has a excellent pool table.
Accommodation wise the best place to stay is at the Lodge, owned by Snowmotions (www.snowmotions.com) . Run by Brits, not only do they offer some good value accommodation but they know this area like the back of their hands and can show you some of the best spots. For 2009/10 the Hotel Krone started offering some dorm style accommodation at around the 45CHF a night mark.
