Another culturally significant peak within the park is The Black Tusk, which is known to the Squamish people as t'aḵ't'aḵ mu'yin tl'a in7in'a'xe7en.

The views from the peaks inspired the establishment of summer climbing camps at Garibaldi Lake, which included among their ranks many members of the newly formed British Columbia Mountaineering Club.

[8] Today, Garibaldi park is a popular location for outdoor recreation, and has experienced greatly increased usage within the past decade.

Much of this landscape was shaped by Quaternary continental and alpine glaciation, as well as volcanic activity such as the eruption of Mount Garibaldi some 13,000 years ago.

[14] The instability of The Barrier was brought to public attention in the 1970s, eventually leading to the area below it being declared unsafe for habitation in 1981.

[15] In 2007, a study on glacial recession in Garibaldi Park was conducted by the Department of Earth Sciences at Simon Fraser University.

[16] A similar study in 2013 by the same authors reinforced that the park's glaciers, along with others in western Canada, are at the smallest they have been in several thousand years.

The lower slopes of the park, between 1,000 and 1,700 metres (3,300 and 5,600 ft) above sea level, are dominated by dense forests of douglas-fir, western red cedar and western-hemlock.

Forests of mountain hemlock, yellow cedar, alpine fir, and white bark pine are present in the higher elevations, and these eventually give way to parkland featuring the characteristically stunted trees of subalpine climates.

[19] Wildlife thrives in Garibaldi Park, including mammals such as grizzly and black bears, mountain goat, deer, marmot, and pika.

A number of birds are present in the park, including the American three-toed woodpecker, common raven, Canada jay, and ptarmigans.

[21] The goal, supported by the provincial conservation framework of BC, was to maintain healthy, viable populations of the animal, thus preventing it from entering "at risk" status.

Garibaldi Provincial Park is a prominent outdoor recreation destination, featuring many kilometres of hiking trails, campgrounds, and winter camping facilities.
