Responsible recreation & Leave No Trace

Know before you go
Check the operator's site for hours, permit requirements, seasonal closures, and fire restrictions before heading out.
Stay on trail
Stick to marked paths to protect vegetation, prevent erosion, and avoid disturbing wildlife habitat.
Respect wildlife
Observe from a distance, never feed wildlife, and store food securely if camping is permitted on-site.
Pack it in, pack it out
Carry out all trash, food scraps, and gear. Many parks have limited or no trash service.
Leave what you find
Don't take rocks, plants, or artifacts. They make the park what it is for the next visitor.
Around the park

Plan a longer trip

The closest fishing spots, campgrounds, boat launches, and points of interest so you can build a full day around the park.

Set push alerts in the Snoflo app

Save Shasta-Trinity National Forest as a favorite, set a custom threshold (precipitation, freezing temperatures, fire-restriction days), and the iOS app will push the moment conditions cross.

Land designation

Park & land designation reference

A quick legend for the federal and state land categories Snoflo tracks. Each designation comes with different rules around access, recreation, and resource extraction.

National Park
Large protected natural areas managed by the federal government to preserve significant landscapes, ecosystems, and cultural resources; recreation is allowed but conservation is the priority.
State Park
Public natural or recreational areas managed by a state government, typically smaller than national parks and focused on regional natural features, recreation, and education.
Local Park
Community-level parks managed by cities or counties, emphasizing recreation, playgrounds, sports, and green space close to populated areas.
Wilderness Area
The highest level of land protection in the U.S.; designated areas where nature is left essentially untouched, with no roads, structures, or motorized motorized access permitted.
National Recreation Area
Areas set aside primarily for outdoor recreation (boating, hiking, fishing, often around reservoirs, rivers, or scenic landscapes); may allow more development.
National Conservation Area (BLM)
BLM-managed areas with special ecological, cultural, or scientific value; more protection than typical BLM land but less strict than Wilderness Areas.
State Forest
State-managed forests focused on habitat, watershed, recreation, and sustainable timber harvest.
Bureau of Land Management (BLM) Land
Vast federal lands managed for mixed use -- recreation, grazing, mining, conservation -- with fewer restrictions than national parks or forests.
