Environmental & Social Practices

  • Environment

  • Bonanza Creek runs on solar power. Think green and come prepared to save energy. A back up generator is available for mornings and cloudy days.

  • Conservation

  • Ranchers have long been the original environmentalists. Put simply if we don't take care of the land, it isn't going to take care of us. We value the land we work on for many reasons. We value it because of its rich history and because it allows us to work with animals each day wondering what surprises the elements will bring.

    It provides us a way of life that we value and in return we try our best through hard work and dedicated stewardship to leave the land as good as or better than we found it.

    We have made several modifications to the land that we believe have improved it - for us and for fish, waterfowl, antelope, deer and elk that use the land as habitat. These include water conservation, rotational grazing to preserve and improve pasture, and the use of solar energy.

  • hours in the Saddle

    Morning - 2 hours, Afternoon - 3 hours
  • We offer 4-6 hours of time in the saddle per day. On a working ranch, however, hours spent in the saddle can really vary. Bonanza Creek focuses on lots of time in the saddle. We ask that ALL riders be comfortable in the saddle and able to control a horse and ride at a trot. While we’ll match you to the right horse for your ability, some riding experience is necessary. All riders must be physically able to mount their horse unassisted. While we have a mounting block available at the stable, on the trail, stumps, rocks and high ground will provide the only mounting assistance.

  • Private Land - 20,000-40,000 (acres)

  • With private 25,000 acres, the Voldseth Ranch lies partly in the legendary Crazy Mountains and partly in the beautiful Castle Mountains. As one guest put it, our location is "where the prairies meet the mountains". And, we feel, she said it best! You'll enjoy rolling hills, open meadows, and plenty of freedom for riding. Our landscape also boasts of 3 beautiful ponds whereby you can fish.
  • Public Land - more than 50k (acres)

  • We also ride on the Lewis and Clark National Forest. The forest lands were originally created in 1897 which makes this forest one of the oldest forest preserves in the U.S. The forest is named in honor of the members of the Lewis and Clark Expedition, which passed through the forest between 1804 and 1806. Prior to that the region was inhabited by Indians for a period of at least 8,000 years The western Rocky Mountain Division consists of a dense coniferous forest and has numerous species of spruce, fir and pine. The Jefferson Division is dominated by ponderosa and lodgepole pine which prefer a dryer climate.

Meals are home cooked and lots of it! From big country breakfasts to sizzling steaks off the grill, to fresh baked desserts, you won't go hungry. If you require a special diet, just let us know ahead of time.

Detailed Activities

The ranch was originally homestead in 1877 by Norwegian immigrants looking for a better life.

The TG Ranch has been part of the Voldseth/Grande family since 1877 when Martin Grande emigrated from Norway to the United States and settled in Montana. Passed through five generations, the land has been used first to raise sheep and then cattle. Today, the area consists of 30,000 acres and runs nearly 1,500 head of cattle, most of which are Black Angus.

The ranch is currently owned by Norman Voldseth and David and June Voldseth. The name derives from the TG livestock brand first registered by original settlers, the Grande Brothers, in 1882. In 1993, June and David built the Bonanza Creek Guest Ranch, adding the lodge and four cabins to the property.

Today the Voldseth family which are fourth and fifth generations own and work the ranch. It won't take you long to see that our ancestors chose this area not only for its good water and grasses to graze cattle and sheep, but also for its beautiful scenery. The Voldseth Ranch lies partly in the legendary Crazy Mountains and partly in the beautiful Castle Mountains.
