Hiking to Lone Star Geyser: An Unforgettable Experience

Lone Star Geyser is a 12-foot-tall cone geyser known for its predictable eruptions, which occur approximately every three hours. There are actually two eruptions during that three-hour period.

Hiking to Lone Star Geyser: An Unforgettable Experience

As with all hikes in Yellowstone National Park Dogs are not allowed on the trails. Everywhere in Yellowstone is bear country. While you shouldn’t let fear keep you from hiking, it is important to know what the best practices are for hiking in bear country. Always be bear aware and carry bear spray with you on all hikes in the park.

Hiking to Lone Star Geyser

To start the hike, head to the Lone Star Trailhead and follow the paved path along the Firehole River. About 0.9 miles in, you will see a thermal area and two small geysers on the right side of the trail. At 1.7 miles from the trailhead, the path will split, and you should stay to the right to hike the last 0.8 miles to Lone Star Geyser.

Our First Trip to Lone Star Geyser

The Trail to Lone Star Geyser is great for both day hikers and cyclists. It is important to be aware of your surroundings and allow bikers to pass by when hiking. The trail can be buggy during the summer, especially in late June or early July, so it is advisable to bring bug repellent or wear long layers to avoid mosquito bites. You’ll pass through a mix of forest and open meadows, and there are plenty of opportunities to spot wildlife like bison, elk, and even grizzly bears (from a safe distance, of course!).

This is an awesome easy hike and probably our absolute favorite hike in Yellowstone! There were 4 other cars in the parking lot but we didn’t see anyone on the trail. They must have been further in the backcountry. The hike is fairly flat on an old service road.

As you approach the destination, you are greeted by signs of thermal activity – steam rising from the ground and a pungent sulfuric smell hanging in the air. The anticipation builds until you finally arrive at the foot of Lone Star Geyser – a cone-shaped mound surrounded by a tranquil pool of water. It is here that you bear witness to one of nature’s most awe-inspiring spectacles, a towering eruption that spews water up to 45 feet into the air.

The first people we saw were on our way back from the geyser. We arrived at Lone Star Geyser at 8:20 am and it started erupting at 8:22. So happy we caught it just right. It was a nice 5-minute eruption blasting water 15-20 feet in the air. We were the only ones there to witness it at that time. Unbeknownst to us it was a minor eruption and a major eruption would occur 15-20 minutes later. Unfortunately, we didn’t know another eruption was imminent and headed back to the trailhead.

Pro Tip: Look for the log book maintained by the Park Service to see if previous visitors have noted the time of the last eruption. The geyser itself will also give you a clue about its pending eruption. It generally begins percolating about 20-60 minutes prior to eruption and builds for the big event.

Our Second Trip to Lone Star Geyser

During our second year in Yellowstone, we definitely wanted to make another trip to Lone Star Geyser. Again we did the easy 5+ mile round trip hike, this time with Oscar from work. Getting an early start since we had to work in the afternoon, we got to Lone Star Geyser shortly after 7 am. Being the first ones at the geyser that morning no one had written in the logbook since the day before.

Not knowing what time an eruption may occur we wandered around the area checking out the other sites and taking pictures. At about 7:30 Lone Star began percolating and had a minor eruption at 8:14 for about 3 minutes. At 8:36 a major eruption started and lasted around 20 minutes. Water and steam blasted high into the air and we made our way around checking out the show from all angles. What an amazing experience! We were the only ones out there until the major eruption was nearly done. It was a great day!

Once you reach the Lone Star Geyser, take some time to enjoy the spectacle and take a few photos before heading back to the trailhead following the same path.

Tips to help you make the most of your hike to Lone Star Geyser:

  • As with everything in Yellowstone, we highly recommend an early start to the day to avoid crowds and increase your chances of seeing wildlife.
  • Bring plenty of water and snacks, as there are no facilities along the trail.
  • Be prepared for changing weather conditions – even in the summer, temperatures can drop quickly in the backcountry.
  • Stay on the trail and follow all park regulations to help preserve the natural beauty of the area.
  • Make sure to move around the area so you can see the rainbow in the falling water. It makes for a great picture!
  • Finally, be patient and enjoy the journey – hiking to Lone Star Geyser is as much about the experience as it is about the destination.
