There are, of course, many other Dolomite summits which can only be ascended, and should only be attempted, by practised and hardy climbers, for whom great heights and the risks attending their ascent possess no terrors. It is generally conceded that the district provides both for the inexperienced and most experienced climbers some of the most interesting mountain ascents in Europe. In the Dolomite region, especially of recent times, climbing has made extraordinary progress. Summits, the ascent of which a few years ago was looked upon as a great achievement by even good climbers, are now scaled by numbers of people every year; and each year brings additions to the conquered peaks, some of which were a decade ago looked upon as absolutely unclimbable, and likely to remain so. The Dolomites are, indeed, gradually becoming as well known to climbers and would-be climbers of even the countries of Western Europe as are the Swiss Alps, and annually a larger number of lovers of Alpine scenery take their holidays in this region; and of late years the district has been visited by many even in winter time. In summer, although much accommodation has already been provided for tourists, it is, up to the present, decidedly insufficient for all the visitors who flock to this region during the months of July, August, and September. It is, therefore, advisable for any one who wishes for a comfortable time during those months to secure rooms in advance at all places which are to be visited, more especially at those centres of attraction to which the greater number of tourists are in the habit of gravitating.
