The Main Loop Trail at Indian Cave State Park traverses seven miles of forested Missouri River bluff country in southeastern Nebraska, passing the sandstone cave containing some of the state's most significant prehistoric rock art and offering multiple river overlook vantages along the bluff edge. The park is located near the small town of Shubert, approximately 90 miles south of Omaha via US-75 south and county roads to the park entrance at 65296 720 Road. A Nebraska State Parks vehicle permit is required and available at the entrance station or online through the Nebraska Game and Parks Commission.
The loop begins near the main campground and descends through dense hardwood forest of oak, hickory, and walnut before reaching the sandstone formations along the bluff. Indian Cave itself — a large sandstone overhang accessible via a short spur from the main trail — contains Woodland Period petroglyphs estimated to be several hundred years old, depicting human figures, animals, and abstract symbols. The carvings are protected; touching them is strictly prohibited. Interpretive signage at the cave provides archaeological context about the Woodland people who created the art.
The main loop continues along the bluff edge above the Missouri River, with several viewpoints overlooking the river and the Iowa bottomlands across the water. Elevation change over the seven miles is approximately 300 feet (91 meters), with several short steep descents on the bluff faces. The trail surface is primarily packed dirt with tree roots and rocky sections near the bluff edges.
The forested corridor supports exceptional wildlife including pileated woodpeckers, barred owls, wild turkeys, white-tailed deer, and migratory warblers during spring passage. Seasonal streams provide limited water along the route; carrying at least two liters is recommended for summer visits. A park trail map is available at the entrance station and downloadable at the Nebraska Game and Parks Commission website.

Tips for visiting
- Download the park trail map before visiting — cell service inside Indian Cave State Park is minimal and trail junctions require a map
- Carry at least 2 liters of water in summer; seasonal streams along the 7-mile loop are unreliable for drinking
- The petroglyphs inside Indian Cave are fragile cultural resources; touching them is prohibited and grounds for removal from the park
- Visit in October for some of the finest fall foliage in Nebraska — the Indian Cave bluffs rival Ozark scenery during peak color
- Start the loop early to allow 3 to 4 hours of comfortable hiking without rushing; afternoon starts leave little time before park gates close
When to visit
Mid-October is the premier season for fall foliage color on the Missouri River bluffs; late April and early May offer wildflowers and active migratory bird passage. Mornings are cooler and trailhead parking is easier before 10 a.m. on weekends.
Accessibility
The Main Loop Trail involves seven miles of root-crossed forest floor, steep bluff descents, and uneven rocky terrain — it is not accessible by wheelchair or stroller. The Indian Cave spur requires navigating a rocky approach and is not reachable by visitors with mobility impairments. No accessible trail alternatives exist within the main loop route.
Frequently asked questions
What are the petroglyphs at Indian Cave?
The petroglyphs are carvings made by Woodland Period Native Americans, estimated to be several hundred years old. They depict human figures, animals, and abstract symbols in the sandstone wall. The site is protected under state and federal law and touching the carvings is prohibited.
How long is the Main Loop Trail?
The Main Loop Trail covers 7 miles with approximately 300 feet of total elevation gain. Most hikers complete it in 3 to 4 hours at a steady pace, with additional time for stops at the cave and river overlooks.
Is there an entry fee for Indian Cave State Park?
A Nebraska State Parks vehicle permit is required. Annual and day-use passes are available at the park entrance station or online through the Nebraska Game and Parks Commission.
Is the trail suitable for children?
Older children comfortable with a 7-mile hike on root-crossed, uneven terrain can enjoy the loop. The cave and river views are engaging, but the trail length and steep bluff sections make it unsuitable for strollers or very young children.
When is the best time to visit for fall foliage?
Peak fall color in the Indian Cave bluffs typically occurs in mid to late October. The mixed oak, hickory, and walnut canopy produces vibrant oranges and golds, and the Missouri River overlooks are especially scenic during this period.
