Overview: Located four hours north east of San Francisco this Northern California park might be a little out of the way, but it’s a prime destination for seekers of tranquility and those with even just a passing interest in geology.

In geological terms the landscape of Lassen Volcanic National Park is about as young as it gets, and for an example you need look no further than Chaos Crags, a mountain of pink dacite that sprouted from the earth only a thousand years ago.

Even more recent was the Chaos Jumbles rockslide - a massive carpet of rock which separated from the mountain and careened down its flanks at speeds over 100mph, devastating the forest below and only coming to rest after spilling up the side of Table Mountain a whole two miles away.

Our short 3½ mile hike winds through evergreen forest, across the Chaos Jumbles and up to the foot of the Chaos Crags cliffs.

Elevation gain:
• 850ft (from 5,900 - 6,700ft)

Tips:
• Summer through fall is the best time to experience this trail. Snow covers the Lassen landscape for much of the year, closing roads and obscuring trails. See our links below to National Park Service information on road and trail closures.
• Bug repellent is a necessity early in the summer season when mosquitoes are rife.

Manzanita Lake

When the cliffs of Chaos Crags sheared off and tumbled down into the valley they also blocked a local creek, creating what is known today as Manzanita Lake - the beginning of our short 3½ mile hike.

The hiking trail winds its way through a surviving section of thick evergreen forest running parallel to the jumbles, slowly ascending and eventually thinning out as you climb towards the timberline.

The trailhead is located close to the north entrance of the park. Take a turn off the 44 toward Manzanita Lake campground (just next to the visitor center and museum) and the start of the trail is at the first bend in the road.

There's only room for a handful of cars at the trailhead, but there's plenty more spaces available back at the visitor center, or further down the road towards the campground store and restrooms.

Chaos Jumbles

Leaving the forested trail behind, the last part of our journey sets out across the chaos jumbles and negotiates a route through the mess of pink rock fragments.

Chaos Crags Lake

The final destination of this trail is Chaos Crags Lake - though if you're tackling this trail late in the season, Chaos Crags Puddle might be a better name.

Blasted out of the ground by the force of the Chaos Crags rockfall, this large depression in the landscape collects water from the melting snow above, only to evaporate away to virtually nothing by the end of the summer.

If you're looking for a cooling dip however, you have only less than two miles hiking remaining before you're back at Manzanita Lake.
