Bloomington Cave Trail

Bloomington Cave is the most extensive and well-known cave in the St. George Field Office. It is a large tectonic cave, and has at least six distinct levels and a maze of passages that are generally narrow, often with steeply dipping floors. The surveyed length of the cave is currently 1.39 miles (7,340 feet), making it the fifth longest cave in Utah.

This cave’s difficulty level is currently unrated. However, many users who are not experienced cavers have found the cave much more difficult than expected. Bloomington Cave requires crawling, squeezing through tight passages, climbing, and moving on slippery surfaces. Five routes are marked within the cave. Take the virtual tour!

Anyone wishing to enter Bloomington Cave must have a permit. The permit is free and available from the St. George Field Office.

Adventure is at Your Fingertips


Even if you are only planning a day trip, be prepared to spend the night (or two). Equipment problems, bad weather, and unexpected mishaps can leave you stranded. Understand the area you plan to visit and the conditions you will face. Know what it takes to sit it out, self-rescue, or summons assistance.

Getting Around

Use of maps for orientation purposes is recommended, as is knowing the ownership of the land you will be visiting. Maps of property ownership, roads, and other features can be obtained by contacting the St. George Field Office. Also understand the type of terrain you may encounter; this area can be sandy or forested, relatively flat or vertical, and contain copious amounts of slick rock or clay.

Inform Others of Your Plans

Tell someone your travel plans. Leave an itinerary of where you expect to be and when, as well as the make, model, and license of any vehicle you will be using. Make sure they know who to contact in case you do not return as planned.

Dress Appropriately

Be aware that weather conditions can change rapidly and unpredictably. A warm sunny day can quickly turn to rain, snow, or thunderstorms. Bring waterproof rain/wind gear and extra insulating layers. Use footwear appropriate to the activity and environmental conditions. Synthetic clothing and wool provide the most warmth when wet.

Protect Against the Elements

The sun can be relentless year-round. Carry more water than you think you need. Use sunscreen. Consider wearing a hat and a long sleeve shirt and pants even in the summer. Know what the signs and symptoms are of dehydration, heat exhaustion, sunstroke, hyponatremia, and hypothermia.

Carry an Emergency Kit

Pack along an emergency kit appropriate to the season and terrain in which you will be traveling. Consider taking multiple fire starting tools and materials, a portable shelter or tent, sleeping bag, water treatment pills or filter, cookware, stove, extra energy food, ax, first aid items, signaling device, and extra clothes. When traveling by vehicle consider taking a saw, shovel, extra tires and gas, and other items for self-rescue.

Do Not Rely On Electronics

Cell phones, satellite phones, and GPS units may not work due to remoteness and topography. It is a good idea to carry topographic maps and a compass and know how to use them. Also carry signal mirror , a whistle, or other alternative communication device.

Permits and Fees

Commercial outfitters, guides, competitive events, organized groups, vending, and entities conducting business on BLM lands need to possess a Special Recreation Permit (SRP). To obtain more information on SRPs contact the St. George Field Office Outdoor Recreation Planner.

Some campgrounds may require a fee to cover operating and maintenance costs.
