I will be in Yellowstone June 23-25, 2014. I'm staying in West Yellowstone on June 23 because no rooms are available in the park for those days. Everyone has raved about Lamar Valley, but it looks like that would be quite a drive. How long would it take me to drive there from the west entrance. Is there a different area that would be comparable to Lamar Valley for wildlife watching? I will leave June 25 and head south to Grand Teton. Any suggestions?
