How to check if a hot spring or swim spot is legal to visit
Legality comes down to who manages the land, not how popular a spot is online. Five land types (national forest, national park, state park, BLM and private property) set access differently: open by default, permit-gated, fee-based or closed. The land manager's own current page is the only reliable way to check status before a trip.
- National forest and BLM land is usually open by default, sometimes with a parking pass or day-use fee.
- National parks and state parks often charge an entrance fee, and some areas inside them require a separate permit.
- Private land access exists at the owner's discretion and can be withdrawn at any time, with or without notice.
- A closure order from the land manager overrides whatever a map app or an older blog post says.
- "Permit required" and "fee required" aren't the same thing: a permit can be free and still mandatory.
The five land types
Each type sets its own access rules and posts its own closures.
National forest (US Forest Service)
Most Forest Service land is open to the public by default, and most day visits need no permit; fees apply mainly at developed sites. Parking is the more common catch: developed trailheads often sit inside a fee area that takes a regional forest pass (the Northwest Forest Pass in Oregon and Washington) or an interagency America the Beautiful pass. Punch Bowl Falls, on the Eagle Creek Trail in Mt. Hood National Forest, needs a Northwest Forest Pass to park at the trailhead even though the trail itself carries no separate charge.
National park (National Park Service)
Most National Park Service sites charge nothing to enter; many of the best-known parks do charge an entrance fee at the gate, and a few charge for parking instead. Great Smoky Mountains National Park is the best-known example of the last kind: a 1951 deed restriction on its main roads bars the Park Service from charging a toll, so entry is free, but any vehicle parked more than 15 minutes anywhere in the park needs a paid parking tag (National Park Service, Why no entrance fee?). Ramsey Cascades, inside that park, follows the same rule: free to enter, parking tag required.
State park
Each US state runs its own park system, so entry fees and permit rules vary from state to state, and so does the terminology. Georgia's parks use a systemwide vehicle day pass; Tennessee's charge no entry fee at all but sell permits for specific features like a gorge trail. At Tallulah Gorge in Georgia, the rim overlooks are covered by the state's standard day pass, while the gorge floor needs a separate free permit, capped at 100 a day.
BLM land (Bureau of Land Management)
BLM land tends to be the most open of the five, run by local field offices rather than one national fee structure. Many sites are free with no permit at all; some carry a small day-use fee, and a proposed fee can sit pending for years without being collected. Jump Creek Falls in Idaho remains free as of this guide's last check, even though the BLM's Owyhee Field Office has had a $5 day-use fee proposal pending since 2023.
Private land
Private land answers to none of the above: the owner sets the rules, and there's no government fee schedule or alerts page to check. Some private sites operate almost like a business, with posted hours and a fee collected at a gate. Toccoa Falls sits on the campus of a private college in Georgia and charges a small entrance fee during posted hours. Homestead Crater, a geothermal pool in Utah, is run by a private resort at a price the business sets itself.
| Land type | Who runs it | Typical fee or pass | Where to check |
|---|---|---|---|
| National forest | U.S. Forest Service, by individual forest | Often free to enter; a parking pass is common at developed trailheads | fs.usda.gov, Passes and permits |
| National park | National Park Service | Entrance fee at many parks; a few charge for parking instead | nps.gov, Entrance passes |
| State park | The state's own park agency | A vehicle day pass or annual pass, priced by the state | The state park system's own website |
| BLM land | Bureau of Land Management, by field office | Usually free; some sites add a day-use fee by public notice | blm.gov, Permits and passes |
| Private land | The landowner or the business that operates it | Whatever the owner sets, from a posted fee to a donation box | The property's own website; no government source exists |
Permits are not fees
A fee gets you in the door; a permit controls how many people are in a specific place at a specific time, and the two often stack on the same trip.
Multnomah Falls is free to view, but parking at the main lot during its May 22–Sep 7, 2026 season requires a $2 timed-use permit released on Recreation.gov two weeks ahead of each date. The permit exists to manage crowding at one lot; it isn't an entrance charge. Cummins Falls works the other way: the overlook trail is free with no permit at all, but reaching the gorge floor needs a $7 permit capped at 200 a day, closer to reserving a spot than paying to get in.
A fee-only site takes payment at the gate and lets everyone through; a permit-limited site can sell out before you arrive, even if the fee is small or nonexistent. Treat "permit required" and "fee required" in a listing as two separate facts, and check availability as well as price.
How to check current closures
Every land manager posts current closures somewhere on its own site, and that page is more current than a blog post or a trail-app review. Guidebooks and "best hikes" roundups get written once and rarely get updated after a storm or a wildfire changes access; a land manager's alert page gets updated the same day a decision is made.
Check the specific unit's own alerts page: each national forest posts its closures independently of the general Forest Service homepage, national parks post conditions park by park, and state parks list closures on the individual park's page. BLM closures come from the local field office, sometimes as a standalone public notice, so a search for the site's name plus "closure" or "BLM notice" often surfaces something a general site search misses.
Read a closure for its scope, too. A land manager can suspend one activity, such as swimming, while trails and parking stay open, or close access to the whole site; listings on this site say which of the two applies.
Recreation.gov is worth checking separately for anything permit- or reservation-based: a permit system can pause without the land manager's main page mentioning it. When a listing on this site reads "requires confirmation" or notes a specific alert, our sources didn't give a clear current answer; check the linked source yourself before finalizing a trip.
Once you've confirmed access, our waterfall safety, hot spring safety and swimming hole safety guides cover what to check on the ground.
Private land and unofficial spots
Private land carries the most legal risk of the five types, because there's no posted federal or state rule to fall back on, just the owner's permission, spoken or implied. Entering without that permission can be trespassing whether or not a "no trespassing" sign is posted: posting requirements vary by state, and the absence of a sign doesn't by itself create a right to be there.
Some private sites run on a fee-and-hours basis, effectively a small business. Others run on quieter terms: the owner tolerates public access without formally granting it and without charging for it. Meadow Hot Springs is the second kind, spring-fed pools on private pasture land that the owner has left open, with a donation box on site rather than a gate or a posted fee. On this site, a place like that is described as left open by its private owner rather than formally designated public access, and treated as informally tolerated rather than guaranteed, since access depends on one owner's ongoing goodwill and can end without notice.
Swimming holes add one more wrinkle: unlike hot springs and waterfalls, there's no federal or state register of them, so the label depends on who manages the land. A spot on public land with no agency managing or monitoring it at all is listed as "unofficial". The label describes oversight; it says nothing about safety. In our swimming holes in Arkansas guide, Lee Creek is exactly that: gravel-bar access on public river frontage with no managing agency and no lifeguard. A swim spot on National Park Service or Forest Service land that the agency allows but doesn't staff is a different case, listed as "public, swimming allowed, unstaffed" rather than "unofficial".
How this guide was researched
This guide draws on public sources from the National Park Service, U.S. Forest Service, Bureau of Land Management and state park systems, linked throughout, along with the listings on this site referenced as examples. We haven't visited these places ourselves, and every listing referenced here says so on its own page. Access rules and fees change without much notice; verify current status with the land manager before you go. Last checked September 2026.
FAQ
Is it trespassing if there's no "no trespassing" sign?
Treat it that way. Posting requirements vary by state, and in many places a sign isn't what makes private land off-limits; the owner's permission is what makes access legal. Check with the landowner or land manager rather than assuming silence means access is fine.
Do I need a permit to visit BLM land?
For most everyday visits, no. Permits come into play for specific activities, like large group events or commercial guiding, and at a handful of individual sites the local field office manages more tightly. Check the field office's page for the site you're visiting.
What does a day-use fee actually cover?
It depends on the land manager, but a day-use fee is generally a parking or entry charge that funds site maintenance rather than a service fee for anything specific like a restroom or a lifeguard. A fee doesn't necessarily mean a site is staffed or monitored.
How do I find out if a trail or spring is currently closed?
Check the specific land manager's own alerts or conditions page for that exact site rather than a general search result or an old trip report. Map apps and AI-generated summaries pull from cached data that can lag an actual closure order by days or weeks. National forests and national parks post updates by individual unit, and BLM closures are often issued by the local field office as a separate notice.
We haven't visited these places ourselves, and every page says so rather than implying otherwise. Details are compiled from public land-manager, USGS and NOAA sources and cross-checked where possible; conditions, access rules and fees change without notice, so confirm with the managing agency before you go.
