Lago Holly

The most common route to Holly Lake is a challenging 12.8-mile (20.6 km) round-trip hike from the String Lake parking lot, involving an altitude gain of 2,840 feet (870 m). Holly Lake is also a significant side trail along the longer Paintbrush Canyon-Cascade Canyon loop, offering an even more extensive and demanding backpacking experience. Both routes are considered challenging due to significant elevation gain and distance.

Day hiking to Holly Lake does not require a permit. However, if you plan to camp overnight in the backcountry zones near Holly Lake, a backcountry permit is required. These permits are highly sought after, especially during peak season, and should be reserved well in advance through the Grand Teton National Park permit system.

Due to its significant distance (12.8 miles round-trip) and substantial elevation gain (2,840 feet), the hike to Holly Lake is generally not recommended for beginner hikers or families with young children. It is considered a challenging high-alpine trek best suited for experienced hikers with good physical fitness.

No, dogs are generally not permitted on hiking trails in Grand Teton National Park, including the trails leading to Holly Lake. Pets are allowed only on paved roads, in campgrounds, and within 30 feet of roads. Service animals are an exception to this rule.

The Grand Teton backcountry is rich in wildlife. Hikers to Holly Lake might spot various species including deer, marmots, pikas, and a wide array of birds. While less common, larger animals like black bears, grizzly bears, and moose also inhabit the area. Always carry bear spray and know how to use it, and maintain a safe distance from all wildlife.

The best time to visit Holly Lake is typically from late summer to early autumn (July through September) when snow has melted and weather is most stable. Outside of these months, trails can be snow-covered and hazardous. Winter access is extremely challenging and requires advanced mountaineering skills, avalanche awareness, and specialized gear, as the area is prone to heavy snowfall and extreme conditions.

Holly Lake is a remote high-alpine lake within Grand Teton National Park's backcountry. There are no amenities, cafes, or shops directly at or near Holly Lake. Hikers must be entirely self-sufficient, carrying all necessary food, water, and supplies. The nearest facilities are typically found at visitor centers or developed areas within the park, such as Jenny Lake or Jackson Lake Lodge.

While there are no explicit prohibitions against swimming in Holly Lake, the water is typically extremely cold, even in summer, due to its high-alpine location and snowmelt source. Dipping your feet is a common and refreshing activity after a long hike, but full wild swimming is generally not recommended due to the frigid temperatures and potential for hypothermia.

For an average hiker, the 12.8-mile (20.6 km) round-trip hike from String Lake to Holly Lake and back can take anywhere from 6 to 10 hours, depending on pace, fitness level, and time spent at the lake. This estimate does not include extended breaks or detours.
