three peaks, one long day


The Bay Area Region
Summer Solstice, June 21st, 2022

The North Bay Summit Solstice is an annual opportunity to spend the longest day of the year hiking to three of the most picturesque mountain peaks the region has to offer. The individual hikes offer varying elevations and mileage and the in-between-hiking travel logistics combine for a unique challenge designed to test your physical and mental toughness. The question is, do you have what it takes to complete the Summit Solstice?

The Challenge

Summit all three peaks by foot, in any order you choose, on the Summer Solstice (June 21st) or the closest day you can.


You must begin each hike at the designated trail heads listed above and physcially touch the peak.


You can't start hiking until official sunrise and must bag the last peak before official sunset.

This is a marathon (actually more mileage) not a sprint, but for those trying to make our Top 8, please present quantifiable proof of all 3 hikes from the specified TH sign, to peak and back with time and mileage (not driving) and a photo of you to

Is this challenge a walk in the park for you? Add another park to the day by summiting Mt. Wittenberg in Point Reyes. 

The Prize

Pride, Respect, & Bragging Rights!

This is a free challenge but you can definitely buy memorabilia at our swag shop to commemorate your success!

The Logistics

Figuring out your flight plan is half the challenge - but we suggest avoiding high traffic times, coordinating with others for carpools and to lower your carbon footprint, being aware of park hours and fees, and be prepared with food, water, & sun screen. Stretch a bunch, be safe, smart, and please practice leave no trace principles throughout the hikes.

Wear something neon GREEN to show others you are participating!

The Inception

While we admired the panoramic view atop Mount Saint Helena one clear afternoon, my muttered statement broke the silence... "It would be rad to summit all 3 in one day." He looked at me bewildered, so I pointed at Tam and Diablo, both visible from our vantage point. He said, "Is it possible?", then an even better question for two out of shape guys... "could WE do it?" We chose the longest day of the year to supplement for travel logistics and park operating hours. One foot after the other we finally completed (barely) our self imposed challenge and when we reached the final summit some friendly folks cheered us on, "you made it!", and to save face for how wrecked we appeared, "we just climbed this one, that one and that one" (pointing to the other peaks). Their astonishment with our accomplishment led us to make this thing a thing, and thus, the Summit Solstice was born!
