The closest entrance to the park from where I live is the West Entrance through West Yellowstone, MT. From there, it's about another 14 mile drive to Madison Junction where you take a right hand turn to Old Faithful at Madison Junction.
First stop along the way was the Fountain Paint Pot Trail, featuring geysers, mud pots, hot springs and fumaroles along a boardwalk. Plenty of geothermal activity to witness here.
Next stop was Old Faithful, another 17 miles or so down the road past lots more large animals alongside the road to thrill tourists and onlookers. This stretch has some beautiful fly fishing water along the well renowned Firehole River. There were plenty of people out trying their luck on the Firehole yesterday, casting along the river's edge with steaming vents encircling them.
When we arrived at Old Faithful, we had just missed the geyser so we had about a 45 minute wait for the next "performance" so to speak. We walked around and listened to the narration of the park ranger who was making the most of entertaining the huge crowds. Finally, after a long wait, Old Faithful erupted in typical geyser fashion and gave a rather short performance although it was well received by all.
Having such a short amount of time to see as much of the park as possible, we opted to head to Yellowstone Lake in lieu of doing the entire loop that runs from Madison Junction to Old Faithful, Yellowstone Lake's West Thumb, then on to Fishing Bridge, around to Canyon Village and through Norris back to Madison Junction and then on to West Yellowstone.
When we started climbing in altitude to Yellowstone Lake, we climbed to 8,391 feet asl where there was still quite a lot of snow on the ground and the lake was still a good bit frozen, although much of it was melted. We encountered a small grizzly bear that looked like he was having great difficulties coming out of hibernation, skinny and sickly looking. I'm not sure what was wrong with him but he didn't look good at all.
That's about as far as we had time for in one day, so we turned around and headed back to West Yellowstone, stopping along the way for more photo ops and large animal sightings. All in all a great day in the park, which would only have been better if I'd had my fly rod in hand on the Firehole!
