Maya and I set out on an ambitious adventure to break our record for the longest day hike. After extensive research, I stumbled upon this hike on DoingMiles.com which promises over 20 miles of hiking, significant elevation gain, and the allure of multiple lakes. We accepted the challenge.

To maximize daylight time, we woke up early, leaving the Bay Area at 5:30 AM and arriving at Kernfield just before 7 AM. It was easy to find parking along Crown Street and began our hike. The morning fog created a dramatic atmosphere as we set off, encountering a few early risers - hikers, runners, and cyclists - along the way.

Within the first half-mile, we reached Phoenix Lake, our first of four lakes. The sight of sunlight piercing through the fog and reflecting off the water’s surface was breathtaking. Energized by this beautiful start, we continued to Bon Tempe Lake before tackling the steep, unshaded ascent north of Alpine Lake. The summer heat made this climb particularly challenging, and we found that the “lunch spot” marked on our Caltopo map didn’t offer the shade we had hoped for. Undeterred, we pressed on and found a shady respite a short distance ahead.

As we progressed, our trail merged with the Cataract Falls trail, offering picturesque views despite the low water flow typical of late summer. We made a mental note to return in spring to witness the falls in their full, roaring glory. We paused for an early dinner on a small, secluded beach by Alpine Lake, savoring both our meal and the tranquil surroundings.

The afternoon light painted the lakes and surrounding trees in stunning hues, creating unforgettable vistas. We found ourselves largely alone on the trail, adding to the sense of serenity and connection with nature. As the sun began to set, we quickened our pace along the south shore of Bon Tempe Lake, racing against the fading light.

By the time we reached Lagunitas Lake, darkness had fully enveloped us, necessitating the use of our headlamps. This nighttime hiking added an element of adventure to our journey, though it meant foregoing our planned ascent of Pilot Knob 1187. We finally reached the parking lot at 9:30 PM, exhausted but exhilarated by our accomplishment.
