I did this trail 5/31 and was open. some snow but easily passable. swampy in some areas. you can get to lone star either starting at the parking lot just past Kepler Cascades or Howard eaton. I started at Howard Eaton and was about 7 miles. geyser goes off every 3 hrs. first mile is steep on the way up but after that is flat. trail can also be taken to shoshone lake for 16 miles.

Great trail for those little ok’ing to see how the elevation west will impact them. This is more easy than moderate but good for us easterners to get acclimated to then elevation Not a big difference in changes nice sights get updates from rangers on what to be aware of

Nice level trail along the river. Paved in spots. Beautiful landscape. Geyser was not quite as described today. Started bubbling at 2:30 pm, small eruption for 2 min at 3:00 pm, larger eruption at 3:24 pm but only for 5-6 minutes and not a loud steam cycle as described. May have needed to stay a little longer. Still a gorgeous day and worth the wait.

I hiked the trail from the Kepler Cascades to Lone Star Geyser on September 10, 2017. It was a beautiful hike following the Firehole river. The Lone Star Geyser erupted at about 1120am....very impressive Geyser. Water and steam to 30-40 ft for about 20 minutes

Left car parked at Old Faithful and hiked in on the Lone Star Trail. Very easy. Some boiling springs on the way on a side trail. Took the Howard Eaton Trail back for something different. Only reason not a 5 star is the mosquitoes on the trail back.

This is an easy 2.2 mile hike to the geyser and you get to walk along the Firehole river that opens up at Kepler Cascades.
The geyser erupts about every 3 hours and it happens as 2 eruptions. It is very easy to think that the minor eruption is the major one (and few people headed back after that). It takes approximately another 20 minutes after the minor eruption to see the major eruption which lasts for good 10-15 mins.
You can lengthen the hike after the geyser to head to Old Faithful which is approximately another 3.5 mile hike or head to Shoshone lake.
The day we went there the water bubbling started at around 10.10am and then lead to minor eruptions at around 10.20am. We saw the major eruption around 10.40am and it lasted for a long time. The whole spectacle happens for around an hour or so.

The hike is a nice easy hike through a beautiful forest along a river. You can also lengthen the hike with an off shoot spring trail. If you do this hike you need to stay for the geyser. It erupts about every 3 hours. The log tells you the last eruption times. If your there early continue past the geyser for a bit and come back. You can get so close!

Cool geyser.

Saw it erupt this morning at 11:30! The trail is mostly paved and there's nothing too remarkable to see along the way.

Easy trail, we miss the geyser eruption for a few minutes, but nice

Three hours between eruptions. There is a log book that one should write it to help latter hikers know about when the show begins. Flat, partially paved trail. Worth the trip!

Great Hike! About 2 miles out to the geyser. This hike is definitely worth it to see the geyser. You can get really close to the geyser without any fences or railings.

This is a very easy trail that follows a beautiful river most of the hike. I highly recommend this for families with young children.

Wife and I hiked the Howard Eaton Trail to Lone Star Geyser, which begins with a lengthy, steady climb. Once past this climb, the next segment of the trail is an enjoyable stroll through the forest. The next segment involves a descent that isn’t as long or as steep as initial climb. At junction with Shoshone Lake Trail, GO STRAIGHT to continue to Lone Star Geyser. First view of this geyser from the trail is impressive. We waited about 90 minutes for the next eruption (based on time of previous eruption recorded in logbook), and it was well worth the wait. Initial phase of eruption is entertaining, and second phase is quite forceful. Please note: Despite what some guidebooks say, park rangers at Old Faithful Visitor Education Center DO NOT have estimated eruption times for Lone Star Geyser. We returned the way we came, having the trail all to ourselves most of the way to the geyser and the entire way back.

In our group: My wife and I, our 10-year old son and 14-year old niece.

Very easy and fairly flat hike. Eruptions are basically every 3-hours around 10a, 1p, 4p and so on. We arrived at Lone Star around 9:45a and a major eruption started at 10:17a and there was still activity occurring when we started the hike back at 10:45a. Be sure to time it right, arriving early and hanging out for awhile is much better than arriving late and missing out!

Lessons learned: I wish we would have explored the Old Faithful area and watched it erupt before doing Lone Star. We watched Lone Star erupt with just our small group of 4 people and one other person. Old Faithful is over in 2-3 minutes and the experience is shared with a massive amount of people. My niece summed up what I think we were all thinking when she said, "Well, that was disappointing!" So, I would suggest exploring around Old Faithful and get that done and then go to Lone Star Geyser.

Nice wide easy trail. Geyser was amazing. Worth the walk and wait.

Did Lonestar trail. Weather was perfect for a hike. Trail still had snowy patches in last mile to Geyser. Beautiful creek flows along much of the hike. Easy hike.

Would've been great on a bike, but as a hiker starting off a backcountry trip, the pavement was horrible for my feet and knees. The geysir itself is pretty cool if you're lucky enough to see it go, both times I passed it I had missed seeing it by 5/10 minutes.

This is one of my favorite trails in the Yellowstone NP. We took our 3 year girl and she walked the whole way there and most of the way back. This is a very family friendly trail. One of the best features is that this trail follows the Firehole river for a good way. It's very peaceful and not a lot of people. We actually missed the eruption by about 20 minutes but we weren't disapointed.

Easy hike, but one of the most magnificent eruptions in the park.

Good hike, paved for bikers up to lone star geyser, continue after lone star and the trail is great!

Not very crowded but an interesting feature in the middle of nowhere. We biked in 2.5 miles (easy with some up hill) secured out bikes, and then hiked some of the connecting trails in the backcountry. Did not see another person for hours. Just remember to bring bear spray and make lots of noise!

There is a box with a log book, where people write the times of eruption for Lone Star Geyser. It erupts about every 2 1/2 to 3 1/2 hours.
