Grand Teton National Park boat launch access, ramps, boat trailer parking, boat-in campsites, with maps

Almost all of the dozens of lakes in Grand Teton National Park
do not allow motorboats

Jet skis, personal watercraft and submersibles are not allowed on/in any park waters.

Underwater diving / snorkeling are allowed only in Jackson and Jenny lakes, within existing limitations on swimming.

Limitations on swimming/wading include not within 150 feet of the downstream face of Jackson Lake dam, not within marinas, boat mooring areas or in the vicinity of the Jenny Lake ferry boat concession.

Floating any river or stream within the park on an air mattress, float tube, inner tube or similar individual flotation device is prohibited.

Windsurf boards are only allowed on Jackson lake.

Water skiing and other types of towing behind vessels is only permitted on Jackson Lake.


All watercraft must be permitted and inspected.

All motorized and non-motorized boats, canoes, kayaks, windsurf boards and stand-up paddle boards must have a boat permit which you can obtain at any visitor center.

sign says Aquatic Invasive species check station all watercraft must stopIn recent years people have had to pull into a inspection station at / near a park entrance each time they enter the park. If their boat is found to not be clean of aquatic nuisance species, they may find themselves having a park ranger cleaning it:

Rangers on patrol have come to takeouts and check for park and Wyoming annual Aquatic Invasive Species decals (permits). NPS: “A park ranger may, at any time, stop or board any vessel to examine documents, licenses and permits relating to operation of the vessel and to inspect the vessel to determine compliance with boating and fishing regulations.”

The Park says: “User fees for operating a boat within the park help cover the costs for maintaining routine patrols of park lakes and the Snake River. Boating fees also help in supplying equipment and training for aquatic rescue operations.

stop aquatic nuisance species: a sign that says stop aquatic nuisance species from entering the Greater Yellowstone area Boats, and anything that comes in contact with the water (a boat trailer that you drive into the water to launch, waders, paddles, Tevas, nets, etc.) must be cleaned before use in the park. They must be cleaned again before use in Yellowstone waters and again when you come back to the Tetons.

tiny mud snails NPS photo: two tiny mud snails in a dime for size comparison New Zealand mud snails, shown on a dime in this NPS photo, are only about a quarter of an inch long. They form dense colonies on rocks and aquatic vegetation and crowd out native aquatic insect communities, which are a primary food for fish, which are food for many animals. They also eat the majority of alqae growth in streams, which is a primary food for aquatic invertebrates.

Why you need a lifejacket.

How much water is in Jackson Lake (reservoir) right now?

Will I be able to launch my boat at the ramp where I will be staying near, or will I need to go somewhere else?

How much water is in the lake depends on how much snow fall over the winter melts into the lake, and on when and how much the reservoir is drained for Idaho farmers. On many of our fall trips the ‘bay’ at Colter Bay is a mud flat due to irrigation water being drained from Jackson Lake.

In 2021 the park announced:

“Due to very low natural flows and the need to supplement downstream reservoirs, Jackson Lake is expected to drawdown rapidly to levels only seen three times in the last thirty years.

Park concessions with marina facilities, including Grand Teton Lodge Company and Signal Mountain Lodge Company, are modifying operations in accordance with forecasted lake level changes. The Colter Bay boat ramp is expected to close to motorized vessels by Wednesday, July 21. The ramp will still be accessible to vessels that can be hand carried. In addition, it is likely that impacts to Signal Mountain and Leek’s Marinas will occur as early as the end of August or early September. Park visitors with motorized boats should note that recreation opportunities will be increasingly limited in the park.”

Full pool of Jackson Lake (reservoir) is 6769′.
The end of the boat ramp at Colter Bay is at 6753′,
at the end of the boat ramp at Signal Mountain Lodge is 6737′
and at Leek’s Marina it’s 6735′.

This webpage tells you how high the water level has been on Jackson Lake for the last five days. (Scroll down past the drawing at the top.)



When do Grand Teton National Park and Jackson Lake
boat ramps open and close?

Besides the water being drained for farmers, some of the closures dates are dependent on the onset of snow heavy enough to close roads to ramps, and winter wildlife closures. (Grand Teton weather.)

For example, in 2020: most opened June 5, the winter wildlife closure closed everything by Dec. 14.

Colter Bay Marina June 5 – Sept. 20, 2020
Leeks Marina June 5 – Oct. 4, 2020
Signal Mountain Marina June 5 – Sept. 13, 2020


Where and how long can I park my boat trailer
in Grand Teton National Park?

(Please note that you should verify the chart below by reading signs at parking lots.)




You can usually find a fishing line recycling box at each of the ramps and marinas.



The Park Service reminds people in mid to late summer: you can help save native trout by not fishing in warm weather when the water in rivers and streams gets too warm. When the high temps are forecasted to reach 85 degrees, the water may warm up to 68 degrees. Stress caused by catch and release can be fatal to fish. When water temps reach 60 degrees, use heavier line and release the fish quickly after catching it, since fish may be prone to stress. 45 degree water is optimal. Read more at:

Here is a map of Grand Teton National Park launch sites.
Red dots on the map are launch sites for any boat, including motorized.
Green dots are only for non-motorized.
(See below for descriptions and local maps of some of these.)

simple map

The Grand Teton National Park website had this list of ramp and access by type:

Developed ramp indicates trailer access to the water (paved and unpaved),
(some level of access but may not allow for a trailer to be driven into the water),

Undeveloped indicates a need to hand carry a vessel to the water.



“The following sites are designated as vessel launching sites”:

Motorized vessels ramps– Jenny and Jackson Lakes

Spalding Bay (all vessels, undeveloped ramp, no services) – small parking lot and two small campsites at this location. Some years: “Because of limited space, only single axle boat trailers are allowed at Spalding Bay. Trailer parking requires a special parking permit.” Inquire at a visitor center before you drive down the long side road (2.25 miles) from Teton Park Road.

Non-motorized vessels are allowed on Jackson, Jenny, Phelps, Emma Matilda, Two Ocean, Taggart, Bradley, Bearpaw, Leigh, and String Lakes.

Where specific launch sites are not designated, boaters may carry hand-propelled vessels to shore line points where launching is convenient unless otherwise posted.

Jackson Lake Dam, Snake River Launch
to Pacific Creek Landing,
Snake River Launch and take out

A five mile stretch of the Snake River from Jackson Lake just above Oxbow Bend, down to the raft launch just past Pacific Creek at the landing north of the Moran entrance station, is great for canoes and kayaks. People sometimes plan to shuttle cars.
(Most canoe / kayak rental companies do not let people use their rentals on the river at all.)

Here is the route, left to right along the stretch of river in this map:

simple map of river


aerial photo of stretch of river

On the way to the launch point, coming from the north (Colter Bay, for example), a signed section of the “Teton Park Road (TPR) between Jackson Lake Dam and Jackson Lake Junction with dense vegetation along the road is closed to all stopping, standing, and parking. This is a year-round closure.”
See the red stripe on the map below:

People start at a formal launch point down a side road from Teton Park Road (TPR), (the white circle of roadway to the right of the word “Access” on the map below)

“The Snake River for 150-feet below the downstream face of the Jackson Lake Dam is closed to fishing, swimming, wading and / or bank use.”

A 2022 press release said, in part: “. . . Beginning September 6, and possibly into the spring of 2023, it is anticipated that a temporary closure of the visitor area below Jackson Lake Dam, on the north side, will go into effect. The park will provide updates later this summer about the temporary closure and alternative access suggestions for visitors.
The design for the Jackson Lake Dam launch will provide improved boat launching conditions and the addition of accessible site features. Features include a boat ramp which will accommodate two vehicles at a time, fully accessible sidewalks leading to two accessible fishing platforms, expanded parking, and improved site amenities including picnic tables, bench seating, and bicycle parking. Additionally, visitor use areas for viewing and providing educational information about the Snake River will be established…”

All along this stretch of the Snake River there are often people fishing from boats
(below is a photo near Pacific Creek landing):

At the end of the down river paddle there is a formal landing point, sometimes with a line of trailers waiting to get their boats up the driveway from the river to the road, at Pacific Creek Landing, just downriver from where Pacific Creek enters the river.

There are few obstructions along this 5 mile stretch of the Snake river and only a couple of islands to go around.

A bit further downriver from the Pacific Creek takeout the Snake River has many braided sections. Professional guides can take people on this stretch, but the general public, (even experienced boaters) are discouraged due to risk of getting lost, capsized or having their canoe wrap around a tree in the sometimes fast moving sections of the river.

The park service notes: “Though the Snake River in Grand Teton National Park does not consist of any whitewater, it is a complex and unpredictable braided river. A strong current, shifting channels, numerous logjams, eddies, and snags all combine to make floating the Snake a challenging proposition. These obstacles often require floaters to set up maneuvers well in advance, and inexperienced pilots often make maneuvers too late.”

Sometimes boaters have needed to ask people picnicking or just sitting at the lakeshore at the end of the canoe launch ramp to move so they can get their canoe through to the water:

NPS lightning 1: NPS lightning 2: NPS lightning 3:
It is dangerous to boat / swim during a lightning storm ,
and wise boaters do not even launch if a storm is approaching,

even well before they first time they hear thunder.


The park had this warning:
“Lightning: Afternoon thunderstorms are common. Plan your trip accordingly; find a safe place before a storm hits. Avoid exposed summits and ridges, open areas and lone trees. Forested areas with trees of similar height are safer. Do not stand on tree roots. If boating, get off the water.”

You are never fully safe outside:

NOAA lightning sign: sign that says when thunder roars, go indoors

A very accurate local weather report has lightning predictions:

Using the lightning strikes links below you can check out where the storm lightning hits are moving
and it can help you decide
if you are launching your boat, going swimming, taking a shower now or later, and when you actually hear thunder you can check out where lightning hit (closer to Yellowstone, or nearby in the park, or . . . YIPES, that really was nearby!).

Lightning strikes in the last 24 hours are recorded at:;x=-108.2102;z=7;t=1;m=oss;r=0;s=0;o=0;b=27.83;n=0;d=2;dl=2;dc=0;ts=0;

warning signs of hypothermia drawings
The park had this warning:
“Hypothermia (lowering of body temperature) is a serious condition that may lead quickly to death. Hypothermia is often due to exposure from a storm or a swamped boat. Watch for signs of hypothermia: uncontrollable shivering, incoherent speech and exhaustion. Seek shelter, replace wet clothing and provide warm, nonalcoholic liquids. In serious cases, place the undressed victim in a sleeping bag with another undressed person. Always carry rain gear and extra clothing. Dress in layers and avoid wearing cotton.”

Boat-in camping on Jackson Lake
in Grand Teton National park

map of Jackson Lake with boat-in campsites marked

This map has campsites for motorized and non-motorized vessels.

There are ten boat-in-or-hike-in, or boat-in-only campsites on Jackson Lake in Grand Teton National park.

Only a few of them have views of the Teton range.

They are not reserved through the system that makes reservations for the regular campgrounds, rather they are considered a part of the wilderness backcountry permits system. If you want one the these you should plan in advance and be ready to get online in early January to try to get one of them.
Details about wilderness backcountry permits system (mostly backpacking, but also canoe, kayak or boat into (non-motorized vessels) campsites, are at Grand Tetons backpacking.

You can boat or drive to the 2 small campsites on Spalding Bay on Jackson Lake (2.25 miles) from the Teton Park Road. They have bear boxes as well as pit toilets. Google maps 360 degree view of the launch ramp and small parking lot.

Deadman’s Point is boat-in only.

South Landing is small site a mile south of Signal Mountain, boat in or half mile hike in.

Can I bring my dog on my boat
in Grand Teton National park?

Rangers on patrol enforce pets rules, including

Pets are prohibited from riding in boats on park waters, except for Jackson Lake.”

Pets are prohibited on trails, pathways, and swimming in any park waters.”

“Pets are only allowed on a permitted vessel on Jackson Lake, but not in lakeshore campsites or in the water. Pets are not allowed on the Snake River or any other body of water in the park.”

“Pets are prohibited on trails, pathways, and swimming in any park waters…
Pets must be on a leash (six feet or less), under physical restraint, and within 30 feet of the roadway… ”
“Leave your pets at home. Pets are not allowed on trails or in the backcountry of Grand Teton National Park. They may become lost or prey for wildlife, they can also adversely impact park resources. If you need to bring your pet to the park, consider hosting it at a kennel in Jackson during your outing in the mountains.”
