Point with Emma Matilda Lake and Two Ocean Lake Trails, also considered to be relatively easy hikes in the Jackson Lake Lodge area. Other easy hikes include the Valley Trail which runs from Trapper Lake in the north to the south park boundary near Teton Village and the Jenny Lake Trail which circles the lake. Ranging from moderate to strenuous in difficulty, trails leading into the canyons are rated based on distance and more importantly on the amount of elevation change. The greatest elevation change is found on the Paintbrush Canyon, Alaska Basin and Garnet Canyon Trails, where elevation increases of over are typical. Horses and pack animals are permitted on almost all trails in the park; however, there are only five designated backcountry camping locations for pack animals and these campsites are far from the high mountain passes. Bicycles are limited to vehicle roadways only and the park has widened some roads to provide a safer biking experience. A paved multi-use pathway opened in 2009 and provides non-motorized biking access from the town of Jackson to South Jenny Lake. Boating and fishing Grand Teton National Park allows boating on all the lakes in Jackson Hole, but motorized boats can only be used on Jackson and Jenny Lakes. While there is no maximum horsepower limit on Jackson Lake (though there is a noise restriction), Jenny Lake is restricted to 10 horsepower. Only non-motorized boats are permitted on Bearpaw, Bradley, Emma Matilda, Leigh, Phelps, String, Taggart and Two Ocean Lakes. There are four designated boat launches located on Jackson Lake and one on Jenny Lake. Additionally, sailboats, windsurfers, and water skiing are only allowed on Jackson Lake and no jet skis are permitted on any of the park waterways. All boats are required to comply with various safety regulations including personal flotation devices for each passenger. Only non-motorized watercraft are permitted on the Snake River. All other waterways in the park are off limits to boating, and this includes all alpine lakes and tributary streams of the Snake River. In 2010, Grand Teton National Park started requiring all boats to display an Aquatic Invasive Species decal issued by the Wyoming Game and Fish Department or a Yellowstone National Park boat permit. In an effort to keep the park waterways free of various invasive species such as the Zebra mussel and whirling disease, boaters are expected to abide by certain regulations including
