Grand Teton with kids.

Which summer month with kids?

July is Grand Teton's busiest month, averaging about 732,000 recreation visits. Our pick for a school-break trip is August. It runs 8% below July and is almost as warm, with an average high of 76°F at the Moran weather station near Jackson Lake. NPS says mountain trails and passes may not be snow-free until late July, and August comes after that. June is the quietest of the three, but it is the coldest and the wettest, and NPS says valley trails are snow-free only by mid-June.

• June. 14% fewer visits than July. Average high 67°F, low 37°F, 1.8 inches of precipitation.
  Watch for: cold mornings, and snow on valley trails until mid-June. Go in the second half of the month.
• July. The busiest month. Average high 77°F, low 42°F, 1.0 inches of precipitation, the driest of the three.
  Watch for: full trailhead parking, and afternoon storms, which NPS says are common in summer.
• August. 8% fewer visits than July. Average high 76°F, low 40°F, 1.3 inches of precipitation.
  Watch for: the same afternoon storms. Trailhead parking still fills early in the day.

Temperatures are NOAA 1991-2020 normals at Moran 5WNW (USC00486440, 6,805 ft). Treat them as a preview: we have not finished reviewing that station for this park.

If school lets you go later, September averages 77% of July's visits, with an average low of 34°F, and NPS says park visitor centers begin to close that month. The best time to visit Grand Teton page compares every month.

Junior Ranger.

Grand Teton's Junior Ranger booklet is The Grand Adventure, an activity booklet for children of all ages, and NPS says it is available at any park visitor center. Kids earn a Junior Ranger badge by completing the activities for their age. NPS prints no minimum age. For help with the booklet, NPS says to check at visitor centers or the park newspaper for ranger-led programs and suggested activities (NPS Junior Ranger page).

If the booklet comes home unfinished, you can still get the badge. NPS says to mail the completed booklet to Interpretive Park Rangers, Grand Teton National Park, PO Box 170, Moose, WY 83012.

Traveling in spring? Junior Ranger Day is the first Saturday in May at the Craig Thomas Discovery and Visitor Center in Moose. Families can play park-themed games, explore rescue vehicles, learn from a ranger, and earn the badge, and the Grand Teton Association takes 15% off bookstore purchases. The event is free. The park's 2026 hours page lists the Craig Thomas center as open April 10 to October 31.

In summer, the Colter Bay Visitor Center is open (May 8 to September 30 in 2026), and its rangers lead guided hikes, short talks, demonstrations, and evening programs. You can also see art by the artists of the Indigenous Arts and Cultural Demonstration Program there. We do not track the program schedule, so ask at a visitor center (NPS Colter Bay page).

The safety rules kids need to hear.

Bears. Black and grizzly bears live throughout the park, and NPS says bears are often seen on trails and in developed areas at Jenny Lake. On a hike, NPS says to make noise, hike in groups of three or more, and carry bear spray you know how to use. It recommends bear spray in all areas of the park, kept where you can reach it right away, not in your pack. Teach kids the first rule before the trip: do not run. NPS says bears can easily outrun any human, and running may bring an attack from a bear that was not aggressive (NPS bear safety page).

Water. Swimming, wading, boating, and floating are at your own risk, and there are no lifeguards anywhere in the park. NPS says glacial lakes and the Snake River often stay below 60°F, and hypothermia can set in quickly, even on a warm day. Even shallow water can sweep you off your feet, and NPS does not recommend swimming in the river. Its advice for families: assign a water watcher, because distractions can be deadly. Children under 13 must wear a life jacket whenever a boat is moving, unless they are inside an enclosed cabin (NPS safety page).

Wildlife. Stay at least 100 yards from bears and wolves and 25 yards from all other wildlife, in your car or on foot. Never get between an adult animal and its young. Feeding wildlife is illegal, and that includes ground squirrels and birds, so keep the snacks in the pack. A football field from goal line to goal line is 100 yards, so a quarter of one is the closest you should be to a moose.

Storms, altitude, and water bottles. NPS says afternoon storms are common in summer, so get to a safe place before one hits, and get off the lake if you are boating. High elevation may cause breathing difficulties, so pace the day. Dehydration is common and can be serious, so carry extra water for everyone.

Short walks, lakes, and wildlife stops.

Jenny Lake. The paved Discovery Trail runs 0.35 miles to the lake, with wheelchair access and panels about wildlife and history along the way. If you have a stroller, the paved paths here are the ones to use. NPS also describes a viewpoint where a wheelchair can roll to the edge of the lake. For a real waterfall without a long hike, take the Jenny Lake Boating shuttle boat across (fee charged). Its 2026 season runs to September 30. NPS puts Hidden Falls, a 100-foot cascade, 1 mile from the west boat dock and Inspiration Point 2 miles, against 5 and 6 miles round trip from the visitor center. NPS says the east-side dock, the bridge, and the shuttle boats are wheelchair accessible (NPS Jenny Lake page).

String Lake. A 0.5-mile trail of uneven compacted dirt, with log benches, follows the east shore to the picnic area, where two vault toilets are accessible. Past the picnic area the path climbs a few steps onto uneven ground with rocks and roots. Canoes, kayaks, and paddleboards are allowed on String Lake, and the cold-water rules above apply here as much as anywhere.

Colter Bay. A paved, mostly level 0.3-mile path follows Jackson Lake's shore from the Colter Bay Marina; NPS says it is easiest to reach through the amphitheater north of the visitor center. NPS also calls the Lakeshore Trail an easy walk and the Heron Pond and Swan Lake loop an easy loop. There is a Swim Beach, and NPS says mornings often bring calmer water for paddling. NPS lists guided trips from here too, including a breakfast cruise and Snake River floats (NPS Colter Bay page), but the park's hours page shows the Colter Bay Marina's 2026 season ending in August, so ask what's still running.

Wildlife from the car. NPS says dawn and dusk are the best times to see animals, which rest in the shade in the heat of the day. Good roadside stops are Oxbow Bend, about 7.5 miles south of Colter Bay, known for moose, elk, and sandhill cranes; Willow Flats Overlook, 6 miles south of Colter Bay, for elk and moose; and Blacktail Pond, half a mile north of Moose, where elk graze in the cooler parts of the day. Watch from your vehicle, use the pullouts, and do not stop in a travel lane. Binoculars make the 25-yard rule easy to keep (NPS wildlife viewing page).

Mormon Row. No hike needed. Drive about 1 mile north of Moose on US 26/89/191, then east on Antelope Flats Road about 1.5 miles. Bison and pronghorn graze along Mormon Row and Antelope Flats Road in spring, summer, and fall, and NPS says photographers from around the world stop at T. A. Moulton's barn to shoot it with the Teton Range behind. In September 2026 NPS lists the historic district as open, with access to some buildings closed for construction.

A Snake River float. Signal Mountain Lodge lists float trips, and guided floats also start from Colter Bay. NPS says the Snake is a powerful river that takes river-reading and navigation skills, so with kids a guided trip is the sensible way to go. We could not verify an outfitter's minimum age, so ask when you book.

Logistics that make or break the trip.

Parking. NPS says trailhead parking fills early in the day in most summer and fall months, especially at Jenny Lake, String and Leigh Lakes, and the Laurance S. Rockefeller Preserve. In summer the Jenny Lake lot fills and you may have to park along the road, pulled fully off the shoulder. With kids, do Jenny Lake first thing in the morning and save the car-based wildlife stops for evening.

Driving. The night speed limit on the main highway is 45 mph, and NPS says to watch for animals on the road, especially in the evening and morning. That is also when kids are most likely to spot them. In 2026, plan on 20-minute construction delays at the Moose Entrance through November 15, not counting the entrance line. Every road closure and delay is on Grand Teton road closures.

Where to stay. NPS says all lodging and campgrounds in the park are reservable and can fill months in advance. Its lodging page lists Jackson Lake Lodge as open mid-May to early October, Colter Bay Cabins late May to late September, and Signal Mountain Lodge early May to mid-October (NPS lodging page). For families, Colter Bay puts the Swim Beach, easy trails, and a visitor center in one place. Outside the park, the town of Jackson is 20 miles south of Moose Junction. Campground seasons are on Grand Teton camping.

Money. A $35 vehicle pass covers everyone in the car for 7 days, and children under 16 need no pass even on foot or a bike. A U.S. fourth grader gets a free 4th Grade Pass. Grand Teton has been cashless since May 1, 2026, so bring a card, and Yellowstone charges its own entrance fee. Details are on Grand Teton fees.

Getting there. Jackson Hole Airport is inside the park, the only commercial airport in a national park, with rental car counters in the terminal. Road miles from every nearby airport are on airports near Grand Teton.

Common questions.

Is 2 days in Grand Teton enough with kids?

For the family highlights, yes. NPS gives no recommended length, so this is our read of what two days hold. Spend the first morning at Jenny Lake, on the Discovery Trail and the shuttle boat to Hidden Falls, then have a picnic at String Lake. Spend the second day at Colter Bay, with the lakeshore path and the Swim Beach, and finish at Oxbow Bend or Willow Flats around dusk for wildlife. Add Mormon Row on the way in or out. Longer hikes into the canyons need more time and older legs.
