We highly recommend booking this private tour. We did two days. Our guide, Jeremy knew the best places to go. We saw a grizzly, bison, red fox, mountain goats, pronghorn and elk. We missed a pack of 6 wolves by 30 minutes. We had a private lunch w/picnic table, on a lake surrounded by fir trees.Jeremy was knowledgeable about locations, geography, animal behavior, good identify all the birds & kept us at the proper distance to view animals. Jeremy could spot animals quickly. We were set up to photograph mountain goats w/tripod & Jermey spotted a red fox behind us & across the road. The vehicle was comfortable, food & snacks & drinks were quite good. Having a guide is worth every penny even if you need to hold off your visit to save up for it. If this doesn't convince you, these guides know the best restrooms around the park. If you can go in October!
