We did the end of the trail from the road to undine falls- it was just 1 mile round trip and super easy. Highly recommend- no mud either! Quick 20 min hike.

8/17/2018. We hiked this trail from the lava creek trail head parking lot out towards Undine Falls and back again. Steep downhill to get to the suspension bridge crossing the Gardiner River - a fun trail addition, especially the signs warning people not to try and get their horses to cross the bridge! You’ll walk through tall sagebrush and grasses, so be sure you have bug spray as well as your bear spray. We ran into three other hikers and spotted some elk grazing by the river. The trail shows signs of being VERY muddy earlier in the year, making the footing somewhat difficult. Hikers and large wildlife had churned it up pretty good, and it dried into a lumpy mess. Boots are a must here. We saw lots of signs of wildlife and an elk carcass, but no large animal sightings except the two elk. We started our hike at 9:30 am. Very pretty scenery along the river and at one spot in the trail you are close enough to get down to it.

Hiked from Lava Creek Trailhead to Mammoth Campground. It's almost all downhill this direction. Had the trail to ourselves; a rarity in Yellowstone. Beautiful, easy 4 miles.

Wildflowers were at their peak for a good 1.5 miles of the trail. Trail was pretty easy until the last .5 mile and doesn’t bring you right to the waterfall as expected. We went off trail and walked across creek to new trail to a road by the Undine Falls lookout. Saw quite a bit of wildlife and definitely enjoyed the suspension bridge which was early on.

We started at trailhead near Undine falls. Hiked to get a closer view of falls about 1/2 mile

We left one car at Mammoth visitors center and drove the other to the trailhead. This was a great trail with amazing views. It dips down by the Uline Falls close to the top and then you essentially walk downhill all the way to the Gardener river where you cross on an extension bridge. This is where most would turn back but if you are going one way only, note that you need to walk around the construction area and through the Mammoth Campground.

Leaving from Mammoth Campground around 2:30 PM, we walked down the hillside, crossed North Entrance road (Highway 89), to make our way to the Lava Creek trailhead. We made our descent down towards the Gardner River. The trail is not always well marked, so we built a few trail cairns from rocks as we went along in order to mark the way back. It helps to have a good map, and be fairly good at orienteering. Parts of the trail were in rather poor condition. A heavy rain that had created mud, and then was heavily traveled, not by humans but by the wildlife in the area. We rarely saw a human footprint, so if you would like a lightly human-traveled trail, this is the one. We did not see another person on the trail. The trail needed some maintenance to be called easy. I would place it at moderate with the conditions we traveled. We did not bring our hiking poles thinking that it would be easier than it was. My suggestion would be to bring a hiking pole for at least the comfort of having it along if needed. The trail is heavily traveled by unseen wildlife. We saw evidence of a large kill such as elk or bison (vertebrae) by the side of the trail. (See photo.) The trail was churned up from wildlife use after bad rain and in some places could be an ankle twister if not careful. On our return, the rain started but it was mostly a soft misty rain. My favorite parts of the hike were the suspension bridge and seeing Undine Falls. My boyfriend's favorite parts of the hike were also the suspension bridge and the elk that we saw on the hike back to the campground. We did a lot of singing on the trail (bear deterrent) and the elk were very curious about us. They just looked though, and didn't move towards us. NOTE: Great views of Gardiner River and Undine Falls. On the return, a good far off view of Mammoth. We got back to camp with a bit of cushion before dark; probably around 7 PM. The churned up trail made our hike longer than the 3 hours indicated.

Finding the trail head was a little tricky. But once I got there, I discovered that there were apparently two trail heads that converge near a suspension bridge. I began the trail near a small, wobbly suspension bridge over Gardner River. I wasn't bothered by the bridge having crossed other suspension bridges before. From there, I hiked along the river through sage brush to the convergence of Lava Creek and Gardner River, and walked along it through the canyon. Along the trail I saw mule deer, elk, bison, and a bald eagle. I saw old paw prints of black bear and coyote along the trail. There are a lot of basalt and travertine rocks strewn everywhere too. Near the waterfall is a moderately steep walk up to the shelf next to the waterfall. The waterfall is approximately 100 feet tall in 3 tiers. I could literally walk close to the brink. From that vantage point, I could see the Undine Falls pullout vantage point too. During warm and hot weather, I recommend head gear since part of the trail is through tall sagebrush, where ticks like to base jump to their victims.
