Monarch Butterfly Groves

What’s orange and black and flutters all over? Western Monarch butterflies, of course! These jewel-toned beauties migrate twice per year, like birds. Many other butterfly species are hardy enough to weather a chilly winter, but Monarchs can’t survive in cold northern climes. To warm their wings, they overwinter in a favorite Monarch butterfly grove along the Highway 1 Discovery Route each year between October and February.

During the winter, clusters of orange wings cover the trees in Monarch butterfly groves in Pismo Beach, Nipomo, Los Osos and Morro Bay. (Researchers have counted up to 230,000 Monarch butterflies in a single season at the Pismo State Beach Butterfly Grove.)

As the weather warms in spring, the butterflies begin migrating north. Western Monarchs can travel over 1,000 miles to reach their next migration point. Western Monarchs live west of the Rockies and migrate up and down the West Coast, between southern Canada and San Diego. Eastern Monarchs, on the other hand, live east of the Rocky Mountains and migrate south each winter to Mexico.

A sunny winter day offers ideal conditions to see Monarch butterflies along Highway 1. Monarch butterflies become active when the sun hits their wings. Appropriately enough, mating season reaches its peak near Valentine’s Day ― an animated time at Monarch butterfly groves, indeed! Prepare for a spectacular natural show by bringing water, sunscreen, a jacket, binoculars and comfortable shoes.

Pismo Beach Monarch Butterfly Grove

One of the largest Monarch butterfly colonies in North America, the Pismo Beach Butterfly Grove sees thousands of butterflies annually. During the winter season, Monarchs cluster in the branches of a stand of eucalyptus trees in Pismo State Beach.

These Pismo Beach Monarchs live six months ― nearly five months longer than the lifespan of the common Monarch butterfly. Experts believe this is due to a fat-storing system unique to these migrants.

In addition to butterfly visitors, the grove welcomes people from across the West to witness these majestic creatures in the trees. Throughout the season, trained docents lead daily talks and offer insight into the Western Monarch butterfly life cycle. Volunteers also offer powerful telescopes for seeing Monarchs high in the trees.

Monarch Dunes Butterfly Grove in Nipomo

In Nipomo, the nineteen-acre Monarch Dunes Butterfly Habitat became a preserved sanctuary in 2006. This grove of blue gum eucalyptus trees has been home to as many as 60,000 Monarch butterflies during winter seasons.

An endowment secures management and protection of this precious habitat as a permanent Monarch butterfly migration point for years to come. High winds had historically caused numbers of Monarchs to decrease. An advisory group has planted Monterey cypress trees on the borders of the habitat, though, as a wind buffer for Monarchs. Grove conditions continue to improve, with numbers of overwintering Monarch butterflies increasing annually.

Golf courses

The Monarch Dunes Butterfly Habitat sits at the heart of the Trilogy at Monarch Dunes resort community ― also home to two destination golf courses. Try the championship ‘Old Course” or the newest 12-hole Challenge Course designed by Steve Pate and Damian Pascuzzo.Monarch Dunes Golf Club offers private instruction, as well as dining options on-site.

Volunteer-led tours

The Monarch Dunes Butterfly Habitat offers docent-led tours throughout the winter season. For a list of upcoming talks, contact volunteers at the Monarch Dunes Butterfly Habitat.

Monarch Butterfly Groves in Los Osos

Home to two Monarch butterfly groves, Los Osos offers just the sort of habitat Monarchs prefer: a temperate coastal climate and access to nectar.

Monarch Grove Natural Area in Los Osos

With 18 acres at the end of Monarch Lane in Los Osos, the Monarch Grove Natural Area offers plenty of habitat. With the help of a retired Cal Poly biology professor, this Monarch butterfly habitat is becoming a more welcoming site for Monarchs.

The Monarch Grove Natural Area can be found in the Monarch Grove Homes development just off Pecho Valley Road. From Los Osos Valley Road, turn right on Monarch Lane, just where the road forks left toward Montaña de Oro State Park. Turn right on Del Norte to the Sea Pines Golf Course. Park at the golf course and follow signs to the Monarch Grove Natural Area.

Sea Pines Golf Course

Close to the natural area, enjoy a nine-hole executive course, disc golf course, and footgolf course at Sea Pines Golf Resort. The Central Coast’s only hotel directly on a golf course, Sea Pines offers a driving range, practice area, and dining options. Views of coastal dunes and wildlife also make this course special.

Sweet Springs Nature Preserve in Los Osos

Located on the Morro Bay estuary, this natural preserve has been managed by the Morro Coast Audubon Society since 1989. The 24-acre preserve acts as home to clusters of Monarch butterflies from late October to March. Follow trails through Monterey Cypress and eucalyptus trees and alongside freshwater ponds. In addition to Monarch butterflies, many shorebirds winter here.

To get to the Sweet Springs Nature Preserve from Highway 1,take the South Bay Blvd. exit just east of Morro Bay. Continue on South Bay Boulevard to Santa Ysabel Avenue and turn right. Turn left at 7th Street and right onto Ramona Avenue. The site is located on the right (north) side of Ramona Avenue. A prominent sign shows the entrance to the trails.

Morro Bay Golf Course Monarch Butterfly Grove

At the center of Morro Bay Golf Course, a grove of eucalyptus trees offers its branches for migrating Monarch butterflies. In fact, this Monarch habitat has been known to receive butterflies early ― as early as August, some years. What’s more, the beautiful Monarchs tend to land low on the branches, making them extremely easy for viewers to see.

To reach the Morro Bay Golf Course Butterfly Grove, from Highway 1, take exit 277 toward Los Osos/Baywood Park and turn right onto South Bay Boulevard. Turn right onto Park View Road/State Park Road and stay on Park View Dr. Follow signs to Morro Bay Golf Course.
