we went to Grant Tetons in early July and there was still a bit of snow on some trails and some trails that were closed due to avalange risks. It was also the summer after a winter of record snowfall, not maybe not typical. It was fun though to watch our son play in snow while wearing shorts in July
Grand tetons is absolutely beautiful One of our favorite activites. other htan hiking, was renting bikes at Moose Junction and riding along the bike trail; great way to really take things in.
