Redwood Loop Trail

Big Basin Redwoods State Park

A forested loop among redwoods recovering from wildfire in California's oldest state park


0.7 miles



Trail Type


Elevation Gain

42 feet

One of the region’s easiest trails, this loop is the ideal outing for anyone seeking a self-guided or docent-led stroll among giant redwoods.

Rated “easy” by California State Parks, this 0.7-mile loop is flat, with compact ground in places and natural trails in others, with very slight elevation changes. Having recently experienced extreme wildfire, this is also a forest in recovery, and an opportunity to reflect on the resilience and majesty of the world’s largest trees in California’s oldest state park.

*Trail ratings vary and in this guide you will find information to make the best choice for your health and wellness goals.

Trails Rx Benefits

Unleash the Healing Power of Nature

Trails Rx was established to help you improve your physical and mental health while enjoying time in nature. With guidance from Sempervirens Fund's Wellness Advisor, Dr. Suzanne Bartlett Hackenmiller, we took inspiration from her work with Iowa's Hartman Reserve Nature Center.

The program promotes regular use of these trails, or parks near you, to integrate nature's healing benefits into daily life.

"Research increasingly finds that human health is improved by spending time in nature. Whether exercising, birdwatching, or spending quiet, mindful time outdoors, a host of physical and mental health benefits have been confirmed."

Health Benefits of Unique Features along the Redwood Loop Trail

Give yourself a brain break.

When study participants walked for 90 minutes in nature, as compared to controls who walked in an urban setting, those who walked in nature reported less rumination, or the experience of getting stuck in a cycle of negative thinking. These same participants were then studied in a functional MRI machine, which found they had decreased brain activity in the areas of the brain that are active in depression—specifically sadness, behavioral withdrawal, and negative self-reflection. As you walk Big Basin’s Redwood Loop Trail, notice if your mind clears and mood shifts a bit.

Lower your blood pressure.

Research is finding that time in nature can improve hypertension. One small study compared individuals with hypertension who spent seven days and seven nights in an evergreen forest versus those who spent the same amount of time in a city environment. Those who spent time in the forest environment showed a significant reduction in blood pressure compared to the city group.

Another study looked at a one-day forest therapy program for individuals with hypertension that involved stretching, strolling, sitting and lying on the ground, deep breathing, lying in a hammock, and other non-strenuous activities in the forest. The participants were found to have significantly lower blood pressure during the one-day forest therapy program than they had had during the five days prior to the program. This decrease was maintained at three and five days after the program. It’s interesting to know that the health benefits from time in the redwoods can last beyond the time we spend among them.

Immune boost.

Time in nature boosts the immune system in ways that are still being explored. For example, we know that simply inhaling “phytoncides,” a component in the essential oils from trees, has been found to boost our level and activity of Natural Killer immune cells that circulate in our bloodstream to attack viruses, bacteria, and even tumor cells. Research has found that this benefit lasts for as long as thirty days out from a nature experience, so make it at least a monthly goal to visit the trails!

Body and Mind Contemplation

We believe each place has the potential to reward our senses and bring us peace and mindfulness. In the practice of Shinrin-yoku, or Forest Bathing, invitations are prompts we can give ourselves to invite an inward response to the nature we are experiencing. In this section we offer invitations you might respond to in your experience visiting the Redwood Loop Trail.

Pleasures of Presence

For these invitations sit, stand, or rest comfortably against something solid and close your eyes or lower them to the ground.

Rest comfortably and slowly breathe, in through your nose and out through your mouth. Notice the air: the fragrance, the temperature, and the moisture.

Invitations for the Redwood Loop Trail

Often, we avert our eyes and mind from the deceased. But consider taking a closer look at signs of death and decay in the forest. Use all your senses to see, smell, touch (if it feels safe) and explore such things as deceased insects and animals, forest floor debris, mushrooms, fungi, and plants or leaves with damage. What is happening in these processes? What emotions arise? Is there a message for you here?

You might spend some time jotting down or journaling what you noticed during this experience.

About the Park

Big Basin Redwoods State Park

Henry Cowell Redwoods State Park, located in the Santa Cruz mountains, draws visitors from all around the world. The park’s 4,650 acres offer impressive 360-degree views of surrounding mountains and Monterey Bay, and a diversity of habitats but it is best known for its 40-acre grove of old-growth redwood trees which launched a movement. A visit to this ancient redwood grove, by photographer Andrew P. Hill, more than a century ago helped launch the Sempervirens Club (now, Sempervirens Fund) and the redwood preservation movement.
