The Healing Power of Nature: Exploring Outdoor Museums, State & National Parks for Well-being
In our fast-paced lives, it’s easy to forget the immense benefits of spending time outdoors. Nature has an undeniable power to heal and rejuvenate, offering myriad physical, mental, emotional, and spiritual benefits. From the soothing sights and sounds of a park to the expansive views from a mountaintop, reconnecting with nature plays an essential role in improving our well-being.

Research has shown that green spaces can lower cortisol levels, reduce blood pressure, and promote relaxation. A simple stroll through a park, or even sitting beneath the shade of a tree, can work wonders for calming the mind and body. These spaces also support cardiovascular health, promote social connection, and provide settings for celebrating life’s special moments with loved ones. Whether it’s gathering for a meal or reflecting on a hike through the woods, nature reminds us of the vastness of our planet, sparking awe and a deeper connection to the world around us.
This blog kicks off a new series focused on nature-inspired museums, state and national parks, and local spaces around San Diego.
These places offer the opportunity to explore, educate, and unwind while benefiting from nature’s healing power. To begin, we explore the Tijuana River National Estuarine Research Reserve (TRNERR), a coastal sanctuary that highlights the beauty of wetland ecosystems.

Tijuana River National Estuarine Research Reserve: A Coastal Haven for Biodiversity
Nestled along the southern coast of California, the Tijuana River National Estuarine Research Reserve (TRNERR) spans over 2,500 acres of wetland and coastal habitat. It’s one of the largest intact coastal wetland systems in Southern California, a critical space for wildlife, migratory birds, and environmental research. The estuary is home to more than 370 species of birds, making it a prime destination for birdwatching and nature enthusiasts. Among its protected species are the Light-footed Ridgway’s Rail and the California Least Tern, underscoring the need for continued conservation efforts.
The reserve’s trails, open every day from dawn to dusk, are perfect for people of all ages and abilities. Best of all, they are free to the public.
Visitors can also take part in guided nature walks most Saturdays at 11 a.m. or bird walks on Sundays at 10 a.m. These guided tours offer a deeper dive into the natural world of the estuary. The Visitor’s Center is open Wednesday through Sunday from 10 a.m. to 5 p.m., providing a wealth of information on the reserve’s ecology and conservation efforts. For more details, visit www.trnerr.org.

Trails and Outdoor Exploration
TRNERR offers a network of trails through salt marshes, mudflats, and coastal scrub habitats, inviting visitors to explore and enjoy the natural beauty of the area. Whether you seek a leisurely stroll or a more immersive nature walk, the reserve provides an opportunity to connect with nature in a serene and untouched environment. Guided nature walks are held on the 1st, 2nd, and 4th Saturdays of the month at 11:00 a.m. The first Saturday walk, titled An Eye-Opening Experience Without Sight, is led by Docent Ron, who is blind, and provides an enriched appreciation of native plants through other senses besides sight. The second Saturday walk focuses on the River Loop Trail and its microhabitats, while the fourth Saturday walk connects the wetland to other important habitats.
For a more creative experience, the Explore the Colors of the Estuary nature walk, held on the second Sunday at 2 p.m., combines a guided meditation with a watercolor painting session, allowing participants to express their connection to nature through art.

Guided Bird Walks
The Tijuana River Estuary is a United Nations RAMSAR Wetland of International Importance due to its vibrant bird habitat. Join a trained docent to learn about and observe the birds that call the Tijuana Estuary home or are just passing through, including the endangered Ridgway’s rail. Bird walks are held on the 1st, 3rd, and 5th Sundays of the month, meeting at 10:00 a.m. at the Tijuana Estuary Visitor Center. Walks are free of charge, and binoculars are provided for participants as available.

Conservation and Coastal Habitat Preservation
The Tijuana River Estuary plays a key role in protecting coastal habitats and preserving water quality. As a natural buffer zone, it filters pollutants from the Tijuana River before they reach the Pacific Ocean, helping to protect marine ecosystems. Efforts to restore native plant communities, combat coastal erosion, and manage sedimentation ensure the long-term health of the region’s natural resources.

International Cooperation in Environmental Stewardship
Because of its location near the U.S.-Mexico border, the Tijuana River Estuary serves as a symbol of cross-border cooperation in environmental preservation. U.S. and Mexican conservation initiatives work together to protect the region’s unique habitats, emphasizing the importance of international efforts to preserve natural spaces.
Plan Your Visit
The Tijuana River National Estuarine Research Reserve is open year-round and free to the public. Whether you’re a birdwatcher, hiker, photographer, or simply someone who enjoys being surrounded by nature, TRNERR offers a peaceful retreat where visitors can rejuvenate and learn. Here’s how to make the most of your visit:
- Stop by the Tijuana Estuary Visitor Center for maps and information.
- Bring binoculars for birdwatching.
- Wear comfortable walking shoes and sun protection.
- Respect wildlife and stay on designated trails to preserve the habitat.
Conclusion
The Tijuana River National Estuarine Research Reserve exemplifies the intersection of conservation, recreation, and education. Whether you come for the breathtaking landscapes, the rich biodiversity, or the chance to learn about ongoing conservation efforts, TRNERR is an essential destination for those passionate about nature and environmental stewardship.
There is this concept, known as biophilia, suggesting that we are wired to be connected to nature, and there is something inherently healthy about either having nature in our presence or being present in nature
Being outdoors in nature is an important factor in staying healthy. As Dr. Brent Bauer, a general internal medicine physician at Mayo Clinic, explains, “There’s actually a lot of research on this topic. So it’s no longer just, ‘Nature sounds good.’ We know it’s actually really good.” Studies show that spending time in nature, whether it’s a forest or a park, helps lower blood pressure and heart rate, promoting overall well-being.
This is why healthcare professionals are even prescribing nature time. “More than just saying we should, now we actually have a prescription,” Dr. Bauer adds. Research suggests that the best “dose” of nature is at least two hours a week. So, whether it’s through exploring a natural space like TRNERR or bringing nature indoors, taking the time to reconnect with the outdoors is vital to your health.
We hope this series inspires you to discover how nature can enhance your well-being and reminds you of the restorative power that nature offers.
