We did the 6 line zip-line tour and had a blast! These lines are definitely the longest and fastest ones I have ever zipped on (and I have been on many, internationally). The guides were very good looking, entertaining and professional. I don't recommend going in the winter months because it was freezing up in the mountains. But, it would be a good excuse to cozy up to a hot guide. ;-) There is some hiking involved so do wear appropriate foot wear. Also, the location is absolutely gorgeous. We saw a deer!
