Ok, it maybe just that a person happened to have a bad day. But the only person present in the Tourist Information Office seemed very unwilling to help. So before going, it would be ideal to take your map and ideas of what rather than hope for help for the Information Office in the main square. As a compensations, the locals are very helpful.
Visiting Durbuy in summer would leave you with annoyment. One reason, it shares with some onther "beautiful, picturesque" places this ability to attract as many tourists as it can hold in summer that it's just "disgusting"...
Can you imagine this place in hot summer, crowded, packed with cars and coaches (Uuh! the coaches)...
Unique Suggestions: Go out very early in the morning and very late in the evening? Does it make sense?
Fun Alternatives: Low seasoning is the key... for Venice, Ile de Ré and Durbuy. You will appreciate then beauty, the particularity, the charm without the hords of (sometimes tacky) tourists... I don't think I am a snob saying that.. since it's true!
You would even be pleased to be a "real tourist", trying all activities, experiencing the food... Cooked meats, cheese, beer, smoked meat... produits du terroir.
Rarely have I seen a place where hotels, eating places and tourist shops take up such a high proportion of the available space. The hotels I saw advertised were all upward of €60 - which I find too much.
Only a delightful 7 kilometres away at Barveau I stayed in an en suite room above a wine shop for €35.
Unique Suggestions: Enjoy 'the ambience,' buy an ice or a drink or both and go away again.
Fun Alternatives: Stay in Barveau and walk to Durbuy and back
