The self guided jeep tour was ok. Nothing to do with the jeep rental company at all, but the park ranger was rude as all get out to the 20 cars parked on the side of the road, that were excited to finally see a moose. We may have had higher expectations than we should have of seeing wildlife. Maybe you see more if you take the bus further into the park. The 14 miles you're allowed to drive in a self guided tour, there's little chance of seeing bears or caribou I think. But the jeep company staff were very nice and the vehicle was in good shape.
