Great Basin National Park is at the western end of the area in which the Indian Fremont culture used to dominate.

Great Basin National Park is, despite the name, a mountainous park region. It is in many ways similar to the Sierra Nevada Range of California, and has high, rocky peaks from which small creeks descend into the valleys below.

Approaching the park from Baker, the land is flat until the visitor center is reached; then steep-sided mountains block road travel westward across the mountains at this point within the range. The scenic drive to Wheeler Peak follows the mountain slopes until the mountain range becomes too steep to climb by road.

At lower elevations, sagebrush dominates. Higher elevations include many juniper trees, and these collect in woodlands in some places. The highest elevations have very little vegetation.

There is almost an 8,000 ft (2,400 m) difference in elevation between Wheeler Peak and the valley floor. Weather conditions in the park vary with elevation. In late spring and early summer, days in the valley may be hot, yet the snowpack may not have melted at high elevations. The Great Basin is a high-elevation desert, with low relative humidity and sharp drops in temperature at night. In the summer, fierce afternoon thunderstorms are common. Weather conditions are highly variable, so come prepared for all types of weather. It can snow any time of the year at high elevations.

Due to the elevation, temperatures can get cold at night but quickly get warm when the sun rises, as sunlight does not have to pass through much of the earth's atmosphere before hitting the ground. As a result, it could be 40 degrees above freezing (Fahrenheit), but there could still be snow above 7,000 to 8,000 feet in elevation. Temperatures can be cold during winter in both Baker and Great Basin National Park, but temperatures should get pretty hot in Baker during the summer months.

Backcountry camping does not require a permit, but registration is free and strongly recommended. Stop at a visitor center to register and obtain a copy of the regulations. Registration not only allows the park to monitor use, but also provides critical information in the event of an emergency.

The area in and around the park offers a very limited amount of technical rock climbing. The hazardous nature of the rock the remoteness of the sites are the main contributors to this. All routes in the Wheeler Peak area are hazardous, with deadly rockfalls possible at any time of year. Chiseling, chipping, gluing, or breaking away rock or otherwise physically altering the rock is prohibited. This includes placing bolts or other fixed protection. Clean aid, top-roping, or traditional lead climbing are permitted. The use of motorized drills, hand drills or other portable motorized equipment is not allowed. Free climber registration at park visitor centers is recommended for anyone who plans to climb in the park. Rescue resources are limited and may be hours away; parties should be capable of self-rescue.

Check weather forecasts before hiking in any canyons in the park, since rains can cause the normally dry washes on the east and west sides of the park to suddenly become great rivers that carry large amounts of rain and melted snow from the mountains nearby. Warmer weather can also cause snow melt, although snow melt will occur more slowly and send water down the washes at a steadier rate.
