One look at Bear Lake and you’ll understand why people keep calling it the Caribbean of the Rockies

It’s called the Caribbean of the Rockies

Bear Lake sits on the Utah-Idaho border, 20 miles long and 8 miles wide, glowing a shade of blue you’d expect to find somewhere in the tropics.

The water isn’t blue because of the sky or a trick of light.

The color comes from the lake itself, from chemistry that took hundreds of thousands of years to develop. Once you see it, the nickname makes sense.

But the color is just the beginning of what makes this place worth the drive.

A lake born from earthquakes, 250,000 years ago

Bear Lake didn’t form from a glacier or a river. Earthquake activity along the eastern Bear Lake fault carved out the basin, and the lake has been filling ever since. That was at least 250,000 years ago.

Bannock, Shoshone, and Ute people knew the area long before fur trapper Donald MacKenzie arrived in 1819 and called it Black Bear Lake.

Mormon pioneers settled the valley in 1863, founding Garden City, Pickleville, and Laketown along the shore.

By the early 1900s, resort lodges lined the shoreline and visitors were already making the trip from across the West.

Limestone springs are what turn the water that color

The turquoise isn’t dye, and it’s not algae. Underground springs seep through limestone on the lake’s west side before flowing into Bear Lake, picking up tiny calcium carbonate particles along the way.

Those particles stay suspended in the water column and act like microscopic mirrors, bouncing back the blue end of the light spectrum. Glacier lakes get their color from ground-up rock.

Bear Lake gets its color from water chemistry. The lake also runs low in algae, so the water stays clear enough to see deep into it.

Four fish species that exist only in this lake

Bear Lake is home to four fish found nowhere else on Earth: the Bonneville Cisco, Bonneville Whitefish, Bear Lake Whitefish, and Bear Lake Sculpin.

The lake sat geographically isolated for more than 10,000 years, and the fish evolved to match its chemistry.

Every January, the Bonneville Cisco moves into shallow rocky areas near shore to spawn, and anglers show up with dip nets to scoop them through holes in the ice.

It’s a fishing tradition you won’t find anywhere else in the country. The lake also holds Bonneville cutthroat trout and lake trout year-round.

Three beaches, two states and one marina worth knowing

North Beach on the Idaho side runs more than a mile, with a gradual slope into the water that makes it easy for families with kids.

On the Utah side, Rendezvous Beach near Laketown has calm, shallow water and boat launch access. Cisco Beach on the eastern shore draws people looking for a quieter stretch of shoreline with fewer crowds.

Both state parks have boat ramps, picnic areas, and restrooms.

The Bear Lake State Park Marina on the Utah side rents jet skis, paddleboards, and pontoons if you want to get out on the water.

The raspberry shake has a real origin story

German immigrant Theodore Hildt planted the first raspberry fields around Bear Lake in the early 1900s.

The elevation sits near 6,000 feet, and the cool temperatures and soil conditions produced berries with more sweetness than what you’d grow at lower elevations.

The shake itself is simple: fresh raspberries blended with vanilla ice cream. Shops all over Garden City serve their own versions.

In the early 2000s, a virus took out most of the original plants, but farmers replanted and the crop came back.

LaBeau’s Drive-In has been serving shakes since 1981, and its 10-foot revolving shake sign out front is hard to miss.

Raspberry Days packs Garden City every August

The first weekend of August, Garden City fills up fast.

The Raspberry Days Festival draws more than 20,000 visitors over three days, with a parade, pancake breakfast, craft fairs, rodeos, and nightly dances.

Saturday night ends with a boat light parade on the lake and fireworks.

Roadside stands line the highway selling fresh-picked berries, and every restaurant in town puts raspberries into something on the menu.

The town named the lake’s legendary monster Isabella during a contest held at the 1996 festival, so even the local mythology has a Raspberry Days connection.

Bloomington Lake is a short hike to steep cliffs and wildflowers

If you want alpine scenery without a full-day commitment, the trail to Bloomington Lake delivers. The round trip runs about 1.6 miles with only about 170 feet of elevation gain, so it’s manageable for most people.

The lake sits beneath the steep rock face of Saint Charles Peak at over 9,200 feet, and in early July the trail runs through Parry’s primrose and alpine mountain sorrel in bloom.

One thing to know before you go: the trailhead sits about 12 miles down a dirt road, and a high-clearance vehicle makes that drive a lot easier.

Winter turns the valley into a completely different place

Bear Lake doesn’t slow down when the temperature drops.

When the lake freezes, the Bonneville Cisco spawning run brings ice fishermen out with dip nets, working holes cut through the ice in shallow water near shore.

The Bear Lake Valley has over 350 miles of groomed snowmobile trails that stretch from northern Utah into southeastern Idaho. Beaver Mountain Ski Resort sits in the Bear River Mountains nearby for downhill days.

The Bear Lake Monster Winterfest runs a polar plunge and cardboard boat races, and the Bear Lake National Wildlife Refuge has trails open for cross-country skiing and snowshoeing.

Sandhill cranes and white pelicans at the wildlife refuge

Bear Lake National Wildlife Refuge covers 18,000 acres of cattail marsh, open water, and flooded meadows about seven miles south of Montpelier, Idaho.

Around 100 species of migratory birds nest there, including sandhill cranes, white-faced ibis, great horned owls, and white pelicans.

Spring migration peaks from mid-March to early April as the ice pulls back and large numbers of ducks, geese, and shorebirds move through. You don’t have to be a dedicated birder to enjoy it.

Moose, elk, and mule deer turn up in and around the refuge too, especially in the early morning.

The Bear Lake Monster has a name and its own merchandise

In 1868, settler Joseph C. Rich published a piece in the Deseret News claiming locals had spotted a giant serpent-like creature in Bear Lake.

The story built on older Shoshone tales about large serpents in the water and spread fast across the region. Rich later admitted he made it up, but reported sightings kept coming for decades.

In 1996, a naming contest at Raspberry Days gave the creature an official identity: Isabella.

Today you’ll find her on souvenirs, business signs, and parade floats throughout the valley, a local legend that nobody takes too seriously but nobody quite wants to give up.

A red sandstone meetinghouse built across a frozen lake

In Paris, Idaho, about five miles from the Bear Lake shore, the Paris Tabernacle has stood since 1889.

Mormon pioneers quarried red sandstone and hauled it roughly 18 miles by horse and ox team, including loads pulled across the frozen surface of Bear Lake in winter.

Architect Joseph Don Carlos Young, a son of Brigham Young, designed the Romanesque building.

It sits on the National Register of Historic Places and served the community as both a house of worship and gathering space for more than a century.

The tabernacle closed in July 2025 for major roof and structural work, so check ahead before you make it part of your trip.

Visit Bear Lake in Utah and Idaho

Bear Lake sits about 130 miles northeast of Salt Lake City and about 118 miles south of Pocatello, Idaho.

Garden City on the Utah side is the main hub, with restaurants, shops, and most of the shake stands clustered along the main road.

The drive around the lake takes you through both states, and the Oregon Trail-Bear Lake Scenic Byway connects on the Idaho side.

If you come from the west, Logan Canyon Scenic Byway runs right into the valley and puts on a serious show in fall when the aspens turn.
