Has a very low crime rate does not have a police department but does have a County Sherriff and the California Highway Patrol. Also of note there is few gas stations outside of Weaverville so it would be wise to get gas there, as cell phone service is spotty as you are in the mountains and would not want to be stuck for a long period of time.
- 1 Siskiyou County - Trinity County's northern neighbor is dominated by 14,179 ft (4,322 m) Mount Shasta, the west coast's second-tallest volcano, towering nearly 10,000 feet (3,000 m) above its surroundings; while a summit climb requires advanced mountaineering skills, its lower slopes are great for hiking, backpacking and cross-county skiing. The Volcanic Legacy Scenic Byway links Mount Shasta to Lava Beds National Monument in the county's northeast, home to over 800 lava tube caves, several of which are open to exploration. The county is also a premier destination for birdwatchers, with nearly two million birds passing through Lower Klamath National Wildlife Refuge and Tule Lake National Wildlife Refuge during migrations, and North America’s largest concentration of snow geese arriving in spring.
- 2 Shasta County - Trinity County's eastern neighbor is a land of mountains, lakes and rivers. Massive Shasta Lake, California's largest reservoir, is the "houseboat capital of the world", with rentals available for those who want to vacation on the water. Several spectacular waterfalls can be found in the county, including the 129 ft (39 m) Burney Falls, which Theodore Roosevelt described as "the Eighth Wonder of the World", and McCloud River Falls, which is actually three scenic waterfalls. In the county's southeastern corner, Lassen Volcanic National Park is home to a geologic hotspot highlighted by 10,457 ft (3,187 m) Lassen Volcano. The mountain can be summitted via a steep trail, but plan to do so in the summer - the park's 600–700 inches (1,500–1,800 cm) of annual snowfall make it the snowiest place in California.
- 3 Tehama County - Trinity County's southeastern neighbor, Tehama County has a quintessentially "western" feel, with most county residents employed in ranching, timber or farming, and most tourists drawn to the region for fishing, boating, hiking, and other outdoor activities. The county's largest town, Red Bluff, has a population of only about 15,000 inhabitants, but hosts the Red Bluff Round-Up, one of the west's largest annual rodeos, each spring. While there are numerous streams and rivers, the Sacramento River is the largest, intersecting the county and offering excellent fishing for rainbow trout, king salmon, chinook salmon, steelhead, smallmouth bass, sturgeon, and striped bass.
- 4 Mendocino County - Lying halfway between San Francisco and the Oregon border, Trinity County's southwestern neighbor boasts redwood forests, wineries, breweries, and remote, untouched coastline. In addition to its natural features, the county is home to the largest Buddhist Temple in the Western Hemisphere, the 400+ acre City of Ten Thousand Buddhas in Ukiah. The Mendocino Coast Botanical Gardens, located near Fort Bragg, is a 47 acre public garden with oceanside views. While hikers and backpackers will find no shortage of options, those looking for less strenuous ways to enjoy the scenery can ride the Skunk Train, a railroad that has been in operation since 1885 and takes riders 40 miles through old growth forests and across historic trestles between Fort Bragg and Willits.
- 5 Humboldt County - Located to the west of Trinity County, rural Humboldt County is a land of giant trees, seaside mountains, and quirky towns. Redwood National Park lies in the county's northern region and is home to the world's tallest trees; a walk among the redwoods is an experience that won't soon be forgotten. Backpackers will delight in hiking the remote 25 mile Lost Coast Trail in the county's southwestern corner, a three-day trek through the Kings Range along a roadless and undeveloped section of rugged coastline. For those looking for more urban activities, the towns of Arcata and Eureka feature an impressive number of Victorian homes that date back to the late 1800s.
