In addition to beautiful beaches, Santa Cruz is particularly special because it is home to endless hiking trails, beautiful beaches, and teeming wildlife found on and offshore. From the whales of Monterey Bay to the banana slugs of the forest, a diverse array of creatures call this landscape home.

Every winter, Santa Cruz is graced with a front-row seat to thousands of migrating Monarch Butterflies. But where is the best place to see them? Just a short drive away from your Beachnest vacation home!

Here is everything you need to know about the butterflies of Santa Cruz.

About The California Monarch Butterfly Migration

Monarch Butterflies are known for their rich, orange-colored, black-lined wings with white dots along the edges. They are one of the most famous and well-studied butterflies in the world.

One of the reasons Monarch Butterflies are so famous is the sheer spectacle of their annual migration. Western Monarchs fly south along the California coast each year to wait out the winter at several specific locations.

Fortunately for us, Santa Cruz is one of the places the Monarch Butterflies choose to refuel before continuing their journey down to Mexico! The mild, coastal climate of Santa Cruz, complete with abundant groves of eucalyptus trees, is the perfect winter habitat for Monarchs in search of a temporary home.

When to See the Santa Cruz Butterflies

Winter is monarch butterfly season. Timing is everything if you’re planning a trip to Santa Cruz around the flight of the Monarchs. The butterflies usually arrive in mid-October and remain there until January or February.

The peak season for Monarch Butterflies in Santa Cruz is from November to Early December, when thousands of beautiful butterflies will be fluttering through the Santa Cruz Monarch Butterfly Groves. But don’t worry, the spectacle extends at least through January in Southern California.

Come mid-February, the Monarchs leave their overwintering homes in Santa Cruz and fly in search of the milkweed plants on which they can lay their eggs. This convenient source of food for the species lies in abundance further inland.

The Best Viewing Areas for Monarch Butterflies in Santa Cruz

1. Natural Bridges State Park

• Address: 2531 W Cliff Dr
• Website: parks.ca.gov
• Entrance: $10 Parking

If you want to see butterflies in Santa Cruz, you’ll want to head straight over to Natural Bridges State Beach inside the state park. Here, you’ll see the rare beachfront butterflies in search of milkweed. For larger clusters of yellow wings, you can venture into the eucalyptus groves. The state park’s vast protected area is home to a large Monarch grove of eucalyptus trees, where the butterflies cluster and remain for the winter to wait out the cold. It is the only State Monarch Preserve in California.

The Monarch Butterflies fly all over the park. However, if the temperature is below 55 degrees, the butterflies will cluster together in groups within the trees to stay warm.

While you’re walking along the park’s trails, keep an eye out for the park’s milkweed patch. Monarch larvae live exclusively off of milkweed, where the butterflies come to eat and live, and where female Monarchs come to lay their eggs. You might spot caterpillars, chrysalises, and butterfly eggs at the park’s milkweed patch.

Self Guided Tours

You can take a self-guided walk among the eucalyptus trees or join a free weekend guided tour of the monarch butterfly grove led by park naturalists. These events take place on weekends from mid-October through December, from 11 am to 2 pm. Enquire at the visitor center for more information!

Why Do The Butterflies Choose To Nest Here?

The Monarch Butterflies choose Natural Bridges State Park as their winter home for various reasons.

• Food Sources: The eucalyptus groves grow flowers in the winter, providing the butterflies with a constant food source.
• Shelter: The Monarch grove is sheltered from the wind thanks to its location within the canyon.
• Warmth: The trees allow light to filter through, which helps keep the tropical butterflies warm.

Pro Tip: Pack a picnic; this is a great spot to catch a coastal sunset!

2. Lighthouse Field State Beach

• Address: 701 W Cliff Dr
• Website: parks.ca.gov

Lesser known than Natural Bridges State Beach, Lighthouse Field in Santa Cruz is an excellent spot to observe the majestic Monarch Butterflies as they migrate along the California coast. This expansive field, located just two miles south of Natural Bridges State Park, offers a picturesque setting where visitors can witness the vibrant butterfly clusters amidst the scenic backdrop of the ocean.

The field’s location, situated across from the Surfing Museum on West Cliff Drive, makes it a convenient and accessible destination for butterfly enthusiasts seeking to experience this natural wonder.

Tips for Butterfly Watching in Santa Cruz County

Here are a few tips for visitors to Natural Bridges or Lighthouse Field State Beaches.

1. Bring binoculars and a camera.

Sometimes, especially on colder days, it can be difficult to spot the Monarch Butterflies. If you want to look at the Monarchs, we recommend bringing a pair of binoculars. It’s also a good idea to bring a camera to snap photos of these beloved California visitors.

2. Sign up for a guided tour.

While you’re welcome to explore the Monarch Butterfly Trail in Natural Bridges State Park alone, a guided tour from an expert guide is an excellent way to learn more. Your guide can answer any questions you have about the butterflies and also help you spot them if they’re difficult to see!

3. Bring layers.

While winters in Santa Cruz are mild, they can also be unpredictable. It might be sunny one moment and chilly and rainy the next. Be sure to pack a few warm layers to keep you comfortable.

4. Respect the habitat.

When visiting the butterfly groves, it is essential to respect the natural habitat of the Monarchs. Stay on designated paths and avoid touching the butterflies or their clusters. This helps ensure the safety and preservation of these beautiful creatures and their temporary home during the winter months.
