Along Idaho’s forty-five-mile portion of Highway 89, travelers pass Bear Lake, a natural freshwater body that spans the Utah and Idaho state lines. The lake’s vibrant blue waters have attracted travelers and locals to enjoy its outdoor recreation opportunities since the arrival of Euro-American settlers. Regular visitors have referred to Bear Lake as the “Caribbean of the Rockies,” due to its bright blue color.

Long before Euro-American settlers found Bear Lake, the Bannock, Shoshone, and Ute tribes frequented the surrounding landscape for hunting. U.S. military officers John Fremont and Benjamin Bonneville surveyed this area in 1842. Their findings paved the way for Oregon Trail travelers, who later traversed around the lake en route to Oregon. During the late 19th century, Bear Lake was an informal outdoor recreation site, attracting tourists from across the American West to enjoy boating, camping, fishing, hunting, and swimming at the lake’s bright blue waters.

Multiple ambitious locals recognized the site’s popularity and chose to open resorts with lodging and dining. By 1926, several private resorts operated on Bear Lake’s shores, including Bear Lake Hot Springs, Fish Haven, Ideal Beach, Lakota, and Logan Canyon. In the following decades, some of these facilities expanded to offer indoor entertainment, such as rollerskating at Lakota Resort and dancing at Fish Haven Resort. Alongside outdoor recreation, Bear Lake’s various resorts became popular sites for large gatherings like family reunions and school field trips. During the early-mid 20th century, the Bear Lake resorts received higher volumes of tourists between June and August, leaving their lodging facilities with no vacancies. The Bear Lake resorts would experience increased patronage following the extension of Highway 89 from St. Charles, Utah, to Paris, Idaho, in 1956. These businesses advertised the lake’s accessibility to Salt Lake City residents who could reach their summer getaway via the highway without being too far from home.

Recognizing the site’s popularity, the Utah Bureau of Land Management declared Utah’s portion of Bear Lake a state park in 1962 with plans to expand the marina and harbor that year. In 1963, the Idaho State Land Board designated the lake’s northern shore as a state park. It was not uncommon for travelers en route to Yellowstone National Park to stop and behold the unexpected beauty of Bear Lake. The site grew to such popularity in the 1970s that the two state parks closed temporarily and considered ways to control the expanding crowds. Members of the Bear Lake County Commission and the State Parks Commission in each state considered charging overnight campers additional fees, enforcing a maximum capacity, and enforcing boat speed limits. While the state park directors strove to allow the maximum number of visitors to enjoy the beaches, they agreed that certain regulations were necessary to promote a quality experience for all.

Bear Lake continues to be a popular outdoor tourist destination along Highway 89 throughout the year. Spring and summer visitors can enjoy biking, bird-watching, boating, camping, swimming, and water skiing, while winter visitors enjoy ice fishing for the native Bonneville Cisco whitefish. This unique fishing opportunity has made the lake a popular attraction for such an activity, especially when the fish spawn near the lake’s icy shores in late January each year. Even if highway travelers do not plan to stop at Bear Lake, its vibrant blue waters offer a uniquely scenic view as they cruise by on Highway 89.
