RV travel in Alaska
Alaska is a category of RV trip unto itself. The drive from the Lower 48 is 2,000+ miles through British Columbia and the Yukon before you even cross the Alaska border -- the Alaska Highway (Alcan) is 1,387 miles of mostly two-lane road with serious distances between fuel. Once in Alaska the season is short (mid-May through mid-September is the realistic RV window) and the geography is structured around four corridor highways: the Glenn (Anchorage-Tok), the Parks (Anchorage-Fairbanks via Denali), the Richardson (Valdez-Fairbanks), and the unpaved Dalton (Fairbanks-Prudhoe Bay). The Top of the World and the McCarthy Road are summer-only gravel routes for the adventurous. Plan around the season, the bears, the mosquitoes, and the propane sparseness on the gravel routes, and Alaska is the trip of a lifetime. Plan badly and it becomes a 12,000-mile rescue mission.

Drive onRight

Cell phone use while drivingTexting banned statewide; Anchorage city bans hand-held use; cell coverage is spotty to nonexistent outside the corridor highways -- carry a satellite communicator (Garmin inReach, Zoleo, or similar) for the Dalton, McCarthy Road, and Top of the World.
RV-friendly and RV-restricted highways
RV-friendly
Alaska Highway (AK-2) Tok to Delta JunctionThe Alaska side of the Alcan; paved, two-lane, decent shoulders. Frost heaves common -- slow down.
Glenn Highway (AK-1) Anchorage to TokSpectacular Matanuska Glacier views. Paved, two-lane, well-maintained. Heavy summer RV traffic.
Richardson Highway (AK-4 to Valdez; AK-2 north to Delta)Valdez to Fairbanks via Thompson Pass. Steep grades approaching Valdez.
Parks Highway (AK-3) Anchorage to FairbanksMain Denali NP access. Paved, busy in summer.
Seward Highway (AK-1 / AK-9) Anchorage to Seward/HomerTurnagain Arm scenic drive; well-paved, very heavy summer weekend traffic.
Sterling Highway (AK-1) toward Homer/KenaiKenai Peninsula RV corridor; full of campgrounds and dipnet-fishery access in July.
RV-restricted
Dalton Highway (AK-11 / Haul Road) Fairbanks to Prudhoe Bay414 miles of mostly gravel. Pipeline-construction road; trucks have right-of-way. RVs are legal but most rental contracts prohibit it. Three fuel stops the whole way: Yukon River Camp, Coldfoot, Deadhorse. Carry a spare tire and two cans of fuel. Calcium chloride dust is corrosive -- wash undercarriage after.
Top of the World Highway (Yukon TOW / AK-9 from Tetlin Junction)Mostly unpaved, Canada-side; closes Sep-May with the Eagle Plains ferry. Stunning ridge-top driving. Length-restricted at the Poker Creek/Little Gold border crossing -- check current dimensions.
McCarthy Road (AK-10 to Wrangell-St. Elias)60 miles unpaved, follows old railroad bed with iron spikes occasionally surfacing. Most rentals prohibit. Footbridge at McCarthy -- you walk from the road end, no driving into McCarthy or Kennecott.
Denali Park Road inside Denali NPPrivate vehicles allowed only to Mile 15 (Savage River). Past that, NPS shuttle bus only -- and even the bus has been restricted since the 2021 Pretty Rocks landslide cut the road at Mile 43. Check current park-road status.
Hatcher Pass Road (Palmer to Willow)Mostly unpaved over the pass; closed in winter. Doable in small RVs in summer; tough for big rigs.
National parks and monuments
Denali NP & Preserve$15/person (7 days), $80 America the Beautiful annual. Riley Creek Campground (entrance area) reservable via recreation.gov; RVs to 40 ft, no hookups. Savage River Campground (Mile 13, reservable) the only RV site past the entrance. Teklanika reservable but requires a 3-night minimum and you must shuttle past from there. The Park Road past Mile 43 has been closed since 2021 -- check nps.gov/dena for current status.
Wrangell-St. Elias NP & PreserveFree entry. Largest NP in the US (13.2 million acres). No NPS campgrounds; commercial/state options outside the park. McCarthy Road access only, see restriction above.
Glacier Bay NP & PreserveFree entry. Boat or floatplane access only from Juneau (no road access). RV travel doesn't reach Glacier Bay; visit via cruise or fly-in.
Katmai NP & PreserveFree entry. Floatplane access only from King Salmon; famous for the Brooks Falls bear-viewing platform. No RV access.
Kenai Fjords NPFree entry. Exit Glacier (drivable from Seward) is the only road-accessible portion. RVs to 40 ft at the visitor center lot.
Klondike Gold Rush NHPFree entry. Skagway, AK -- accessed via the Alaska Marine Highway System ferry from Bellingham/Prince Rupert or drive via the Klondike Highway from the Yukon.
Sitka NHPFree entry. Sitka, Baranof Island -- ferry or air access only. No RVs.
Aniakchak / Bering Land Bridge / Cape Krusenstern / Gates of the Arctic / Kobuk Valley / Lake Clark / NoatakAll free; all wilderness. No road access. Bush plane / boat only. Not RV destinations.
Boondocking and dispersed camping
BLM: Alaska BLM exists but is mostly remote and trail-accessed. The Steese Highway (north of Fairbanks) has BLM dispersed camping at the Davidson Ditch and around the White Mountains NRA. Free 14-day dispersed limit is the standard. Most Alaskan boondocking happens on state land (DNR), Forest Service in the SE Panhandle, or at the many highway pullouts -- legal in most cases unless posted.
National Forests: Tongass NF (SE Panhandle) and Chugach NF (south-central) are the two Alaska National Forests. Tongass is mostly accessed by ferry and floatplane; Chugach is reachable from the Seward, Sterling, and Glenn Highways. Free dispersed camping on forest roads where present; 14-day limits. Many developed Chugach campgrounds reservable via recreation.gov; bears are routine campground visitors -- bear-safe food storage required.
Stay limit: typically 14 days per location.
Service stops
Propane: Reliable in Anchorage, Fairbanks, Wasilla, Palmer, Soldotna, Homer, Seward, Valdez, Tok, and Delta Junction. SPARSE everywhere else. On the Dalton Highway you have effectively no propane after Fairbanks -- carry full tanks. Top of the World and McCarthy roads: same. The Alaska Highway between Tok and Whitehorse (YT) has several seasonal stops but plan for none and you'll be fine. Most full-service truck stops at major junctions handle refills; small village stores rarely do.
Dump stations: Anchorage, Fairbanks, Wasilla, Soldotna, and most Kenai Peninsula RV parks have dumps. State campground dumps free for paid guests at many parks. Long gaps on the Dalton (Coldfoot has the only dump for 240 miles each way). Mosquitoes congregate around grey-water dumps in summer -- be quick.
Fuel: Diesel widely available in Anchorage, Fairbanks, Wasilla, Soldotna, Homer, Seward, Valdez, Tok, and Delta. SERIOUS gaps elsewhere. Dalton Highway has only Yukon River Camp (Mile 56), Coldfoot (Mile 175), and Deadhorse (Mile 414) -- diesel mostly available but expect $7-9/gallon and Coldfoot may close briefly between truck shifts. Top of the World: Chicken (AK) and the Canadian Poker Creek border-crossing-area have limited supply Jun-Sep only. McCarthy Road: no fuel between Chitina and McCarthy (60 miles). On the Alaska Highway approach, plan stops at Tok, Beaver Creek (YT, just over the border), Burwash Landing, Haines Junction, Whitehorse. Carry one or two 5-gallon cans for any non-major-route travel.
Weather windows
Best monthsMid-June through mid-August for the interior and Denali. Late May and early September are shoulder windows -- colder, less daylight, but far fewer mosquitoes and lower campground prices. Daytime highs 60-80 F in the interior summer; 50-65 F in coastal SE; below freezing at night above 3,000 ft most months.
Avoid monthsOctober through April for road-trip RVing. Most state and federal campgrounds are closed; the Dalton becomes the realm of ice-road truckers; daylight reduces to 4-5 hours in Fairbanks in December. RV-rentals don't operate. The Alaska Highway is technically drivable in winter but emergency response is hours away and propane heater + fuel sourcing become critical.
Mosquitoes in Alaska are not a joke. Late May through early August they hatch in clouds across the interior -- swarms of hundreds when you open the door. Bring DEET-strength repellent, head nets, screened doors, and stop-thru-the-screen-with-window-closed habits. Smoke deters them in camp; campfires + a citronella coil help. The state's unofficial bird is the mosquito for a reason.
Emergency and road conditions
State patrolDial 911 for emergencies; (907) 269-5511 for Alaska State Troopers non-emergency (Anchorage post). Coverage gaps on Dalton and McCarthy Roads -- carry satellite messenger.
