Jenny Lake is a glacial lake formed roughly 12,000 years ago when glaciers carving Cascade Canyon left behind a terminal moraine that dammed the water, creating a lake of about 1,191 acres with a maximum depth near 456 feet (139 m). It's famous for its mirror-still reflections of Grand Teton, Mount Owen, and Teewinot, and its boat shuttle across to the west shore is the gateway to Hidden Falls, Inspiration Point, and Cascade Canyon β some of the park's most popular short hikes. As of July 2026, this is peak summer season: the South Jenny Lake parking area routinely fills before 9 a.m., and as of May 2026 the entire park went cashless, accepting only electronic payment for entrance fees and services. Treat Jenny Lake as a boat-plus-hike destination rather than a quick photo stop, plan an early start, and check current conditions before you go.
Jenny Lake Boat Shuttle β crosses from the South Jenny Lake dock to the west shore, cutting significant time off the approach to Hidden Falls and Inspiration Point
Hidden Falls β about a 0.5-mile walk from the west shore boat dock through the forest to the waterfall
Inspiration Point β roughly 1 mile beyond Hidden Falls, a viewpoint overlooking Jenny Lake and the Jackson Hole valley
Cascade Canyon entrance β the trail continuing past Inspiration Point, a stretch known for relatively frequent moose sightings
Jenny Lake Visitor Center (the historic Crandall Studio) β built in the late 1920s as photographer Harrison Crandall's studio, now displaying art and natural history exhibits on the Teton Range
East shore trail β leads toward String Lake and offers some of the best reflection views of the Teton peaks on the lake's surface
Good to know
SafetyThis is bear country, home to both grizzly and black bears. Carry bear spray and know how to use it, stay at least 100 yards (about 91 m) from bears and wolves, and hike in groups of three or more where possible, especially in Cascade Canyon.
SeasonThe Teton Range often develops sudden afternoon thunderstorms in summer. Exposed spots like Inspiration Point and the open stretches of Cascade Canyon carry real lightning risk, so start early and plan to be off ridgelines by early afternoon.
SafetyJenny Lake is fed by glacial meltwater and stays very cold even in midsummer, raising hypothermia risk if a boat capsizes or you swim β wear a life jacket if using a personal boat or kayak. The upper Cascade Canyon trail can also hold lingering snow and be slippery into early summer.
RulesAs of 2026, Grand Teton is among the national parks charging a $100-per-person nonresident surcharge for non-U.S. residents (Korean travelers included), in addition to the standard entrance fee. Also note that since May 2026 the park is cashless, accepting only electronic payment (cards, tap-to-pay, mobile wallets) β verify current fees and payment options on nps.gov before you go.
MannersFeeding any wildlife β ground squirrels, elk, anything β is illegal in the park. When pulling over for wildlife viewing, get all four tires completely off the roadway, and stay on designated trails rather than cutting across vegetation.
CautionBuy Jenny Lake boat shuttle tickets only from the official concessioner's booth or website. Anyone near the parking lot or dock offering to get you on 'without the wait' for a fee, or offering to hold a parking spot for you, is not an official park service β it's safest not to engage.
Practical info
From Jackson Hole Airport (JAC), it's about a 30β40 minute drive through the Moose entrance to reach Jenny Lake; there's no public transit, so a rental car is effectively required. The boat shuttle charges a separate fee from the concessioner on top of the park entrance fee, and since entrance fees, the nonresident surcharge, and the cashless-payment policy can all change, confirm current details on nps.gov before your trip.
