Boondocking — camping for free on public land without hookups — is one of the best reasons to invest in an RV solar system. But finding good free campsites is the other half of the equation. The right app can mean the difference between a stunning mesa with perfect sunrise views and a muddy pullout next to a highway.
We tested the most popular boondocking apps across the American West to find which ones actually deliver. Here’s what’s worth downloading and what’s not.
Why You Need a Boondocking App
Free camping on public land is legal and abundant, but finding it is the hard part. Unlike campgrounds with reservation systems, dispersed camping sites aren’t listed in any official database. They exist as informal pulloffs, clearings, and established spots that previous campers have found and shared.
Boondocking apps crowdsource this knowledge. Good ones tell you exactly where to go, what to expect when you get there (cell signal, shade, road conditions), and whether other campers recommend it. Bad ones are just lists of GPS coordinates with no context.
Boondocking is where your solar setup earns its keep. No hookups means your panels, battery bank, and charge controller are your only power source. If you’re still planning your system, our Boondocking 101 guide covers the essentials.
BLM & USFS Land: Free Camping 101
Before diving into apps, a quick primer on where you can actually camp for free. The two biggest sources of legal dispersed camping in the U.S. are Bureau of Land Management (BLM) and U.S. Forest Service (USFS) land.
Bureau of Land Management (BLM)
BLM manages roughly 245 million acres of public land, primarily in 12 western states. Most BLM land allows dispersed camping for up to 14 days in any 28-day period. You don’t need a permit for most areas, but some popular spots (like the Arizona LTVA areas near Quartzsite) require a small fee or seasonal pass.
U.S. Forest Service (USFS)
National Forests allow dispersed camping in most areas unless otherwise posted. The 14-day limit applies here too. Forest roads often lead to beautiful, secluded spots — but road conditions vary wildly. What’s a smooth gravel road in July can be an impassable mud pit in April.
General Rules
- Camp at least 200 feet from water sources, trails, and roads
- Use existing fire rings where available (or don’t make fires at all during fire restrictions)
- Pack out all trash — leave no trace
- No dumping gray or black water on public land
- Check local ranger district offices for area-specific restrictions
Campendium
Campendium is the gold standard for boondocking research. It covers paid campgrounds too, but its free/cheap camping database is the real draw. Reviews are detailed and recent, with cell signal reports, photos, and GPS coordinates.
What Makes It Stand Out
The review quality is exceptional. Users report specific carriers and signal strength (not just “good signal” but “2 bars Verizon, no T-Mobile”), road conditions, noise levels, shade availability, and whether the site is suitable for large rigs. The filtering system lets you search by price (free, under $10, etc.), amenities, and location.
Downsides
The Pro subscription ($30/year) unlocks the best features — offline maps, filtering by cell carrier, and a trip planner. The free tier is usable but limited. The app can also feel slow when loading map views with hundreds of pins.
Detailed trip planning. If you want to research a boondocking spot before you drive there, Campendium’s review depth is unmatched.
The Dyrt
The Dyrt has the largest campground database in North America with over 50,000 listings, and it’s been expanding its free camping coverage significantly. The app has a polished interface and a gamification system where reviewers earn badges and rank on leaderboards.
What Makes It Stand Out
The Dyrt Pro ($36/year) includes genuinely useful offline maps that download entire regions. For boondockers heading into areas without cell service, this is a killer feature. The photo-forward review system means you can visually assess a site before committing.
Downsides
The free camping listings are growing but still lag behind Campendium in some areas, particularly remote BLM land in Nevada, Utah, and eastern Oregon. Some “free” listings are actually just cheap ($5-10) USFS campgrounds, which can be misleading if you’re looking for true dispersed camping.
FreeRoam
FreeRoam is the newest contender and it’s built specifically for boondockers. No campground listings, no KOA reviews — just free and cheap dispersed camping. The app is completely free with no subscription tier.
What Makes It Stand Out
The map overlay system is FreeRoam’s best feature. It shows BLM and USFS land boundaries directly on the map, so you can see at a glance where dispersed camping is legal. Cell coverage overlays from all major carriers let you plan around connectivity needs. The trip planning tool lets you chain together stops along a route.
Downsides
As the newest app, it has fewer reviews than Campendium or The Dyrt. Some areas have just a GPS pin with no reviews or photos. The app is also occasionally buggy, particularly when switching between map layers.
Visual planners. The land boundary overlays make it easy to explore areas you’ve never been and identify potential boondocking spots without relying solely on existing reviews.
iOverlander
iOverlander started as an international overlanding app and has strong coverage in Central America, South America, and Africa — places where no other camping app reaches. For U.S. boondocking it’s solid but not as polished as the dedicated options.
What Makes It Stand Out
Completely free, community-driven, and it covers the entire world. If you’re planning a trip to Baja, central Mexico, or further south, iOverlander is essential. It also lists water fill-up points, dump stations, and mechanics — not just camping spots.
Downsides
The U.S. database is less comprehensive than Campendium or FreeRoam. The interface feels dated compared to newer apps. Reviews are often sparse — sometimes just a GPS point with “nice spot, stayed 3 nights.”
Freecampsites.net
One of the original boondocking resources, Freecampsites.net has been cataloging free campsites since before smartphone apps existed. The website-turned-app has a massive database built over years of community contributions.
What Makes It Stand Out
Sheer volume. For well-traveled areas (Southwest, Pacific Northwest, Colorado), there are often dozens of free camping spots within any given area. The color-coded map pins show at a glance whether a spot is free, cheap, or restricted.
Downsides
The app is functional but far from polished. Many reviews are years old and may no longer be accurate (road closures, new restrictions, land use changes). The filtering options are basic compared to Campendium or FreeRoam.
AllStays Camp & RV
AllStays ($9.99 one-time purchase) is the Swiss Army knife of camping apps. It covers everything from Walmart parking lots to luxury RV resorts, with boondocking spots included. The information density is incredible — it maps cell towers, rest areas, dump stations, propane refills, Harvest Host locations, and more.
What Makes It Stand Out
The one-time purchase price is a breath of fresh air in a world of annual subscriptions. The cell tower overlay shows actual tower locations, not just estimated coverage. For long-distance RV travel planning, the sheer breadth of data points (fuel prices, road restrictions, Walmart overnight policies) makes it invaluable.
Downsides
The interface is information-dense to the point of being cluttered. The boondocking-specific features aren’t as refined as dedicated apps like FreeRoam or Campendium. It’s more of a “does everything okay” tool than a specialist.

Offline Maps & Cell Coverage
The irony of boondocking apps: the best dispersed camping spots are often in places with no cell signal. If your app can’t work offline, it’s useless when you need it most.
Best Offline Options
FreeRoam offers free offline maps with land boundary data included. The Dyrt Pro has the most polished offline experience with downloadable region packs. AllStays works offline with cached data from previous sessions.
Cell Coverage Planning
Before heading out, check cell coverage maps for your carrier. Verizon generally has the best rural coverage, followed by T-Mobile (which has improved significantly with mid-band 5G expansion) and AT&T. If connectivity matters for remote work, consider a cell signal booster and plan your stays around coverage areas.
Download Google Maps or Gaia GPS offline maps for your area before you lose signal. Even if your boondocking app works offline, having a dedicated offline navigation map is essential for finding forest roads and BLM access points.
Our Top Picks
Best Overall: Campendium
For pure boondocking research, Campendium’s review depth wins. The $30/year Pro subscription is worth it for the offline maps and cell carrier filtering alone. If you can only download one app, make it this one.
Best Free Option: FreeRoam
No subscription, no paywalled features, and the BLM/USFS land boundary overlays are genuinely useful. The review database is still growing, but the planning tools are already best-in-class for a free app.
Best for International Travel: iOverlander
If your travels take you beyond the U.S., iOverlander is the only option with serious international coverage. It’s also the most community-driven option, which keeps listings honest.
Best All-in-One: AllStays
For the RVer who wants one app for everything — boondocking, campgrounds, dump stations, fuel, Walmart overnights — AllStays delivers the most data per dollar at a one-time $9.99 price.
We use Campendium for pre-trip research, FreeRoam for on-the-road discovery, and AllStays for everything else (dump stations, water fills, overnight parking). Three apps cover every scenario.
