The Lake Tahoe region has a seemingly endless variety of recreation, activity and history, and one event this weekend will highlight the lake’s uniqueness while encouraging stewardship over the Jewel of the Sierra.

The Tahoe Geotourism Expo, now in its third year, is centered around experiencing the area while doing no harm. The expo uses the “8 Worlds of Tahoe” — sky, water, plant, land, wildlife, community culture and heritage — to connect people to the lake while also entertaining them.

“The goal of the Tahoe Expo is to build a sustainable and prosperous future for the region by harmonizing tourism with the natural environment,” according to the expo’s website. “The Expo features local expertise to welcome and host you to life-changing adventures and the businesses who incorporate sustainability as part of their business model.

“When ‘conservation becomes cool’ … ‘preservation will become profitable’ as visitors have more reasons to stay longer, return sooner and share stories that inspire others to join in the experience,” organizers continue. “This will shift Tahoe’s tourism industry to a stewardship model that includes four seasons of enriching and unique experiences that will support long-term holistic prosperity while achieving 100 feet of Lake Tahoe water clarity.”

Expo experiences are conducted through a series of “tracks,” adventures that entail everything from bird watching to mountain bike riding.

Each of the tracks is guided and will provide people with insights they may not get on their own, while encouraging stewardship over the Lake Tahoe region’s environment, said Jacquie Chandler, the executive director of Sustainable Tahoe and an organizer of the event.

They also give people a chance to try something new.

“If you’ve never fly-fished, try it. If you’ve never kayaked, try it,” Chandler said.

Tracks leave from all around the lake and outside Truckee Saturday and Sunday.

Everyone is encouraged to try activities like stand-up paddleboard yoga, which takes place in Sand Harbor on Saturday, Chandler said.

“It is unbelievably amazing,” Chandler said of the experience of getting out on a paddleboard in the scenic North Shore cove.

Saturday’s tracks include a photo tour in Sand Harbor, a kayak to Thunderbird Lodge, a ride on the East Shore’s Flume Trail and a sports track at the West Shore.

Sundays tracks include a bike, stretch and food at Nevada Beach; fly fishing in Squaw Valley; a treetop adventure in at Granlibakken; trails yoga at Spooner Lake and a discussion of a green home growing dome in Glennshire. A track focusing on the wild mustangs of Nevada also takes place in Reno on Sunday.

New this year will be a Center Stage Showcase from 8 a.m. to 8 p.m. at Lakeview Commons in South Lake Tahoe. The showcase includes Washoe music storytelling and dance, as well a local music, kayak and electric bike demonstrations and a wine and beer garden.

Several adventure tracks also leave from Lakeview Commons Saturday, including an Al Tahoe neighborhood history walk, bird walks and a mountain bike ride with South Shore bike guru Gary Bell.

The expo takes place during what is often the best time of year at Tahoe, when the crowds have left but the weather remains warm.

“September is traditionally the most beautiful time of year in Tahoe – the weather is outstanding, the lake is at its warmest, and there is no summer traffic,” according to organizers. “The Expo adds to the excitement of the Tour de Tahoe by providing fun, educational, and low carbon activities for cyclists, their families, and anybody else who wants to join.”

Prices for the tracks varies. Many are free, including the showcase at Lakeview Commons.

People are encouraged to take public transportation or ride their bikes to Tahoe Expo events. Online registration is encouraged.
