Terminal Geyser
103 mi from Reno · ~3.0 hr drive
Terminal Geyser is a geyser catalogued in California by the U.S. Geological Survey's Geographic Names Information System — about 103 miles from Reno, NV, inside Lassen Volcanic National Park. Coordinates and the closest documented metro are listed below; for current access and soaking rules, check with the relevant land manager before visiting.
Safety & access
This feature is inside Lassen Volcanic National Park and is federally protected. Stay on designated boardwalks and trails — leaving them damages fragile thermal-features and is illegal. Soaking is prohibited in most NPS thermal areas.
Water in geysers and boiling springs reaches well over 180 °F (82 °C) and can scald instantly. Never enter the water. Steam itself can cause burns.
Before you go: check current conditions and access rules with the relevant land manager — National Park Service unit, U.S. Forest Service ranger district, Bureau of Land Management field office, state-park department, or the property owner if it's private. Wild thermal water can be unsafe to enter without a thermometer; surface temperatures can vary dramatically from the deeper pool. When in doubt, don't soak.
