The Eastern Townships countryside around Granby is worth spending time in. The wine region centered on Dunham, about 30 km south, produces some of Quebec's better cold-climate wines — the route along Chemin de Dunham passes a dozen or more small vineyards, several with tastings.
Sutton (50 km south) is a small ski resort town with good hiking in summer and a lively village centre. Mont Shefford and Mont Brome, both within 30 km, have walking trails in summer and downhill skiing in winter.
Bromont (20 km west) has a large water park and is another option for families who have already exhausted the Granby Zoo.
