From family-friendly Halloween festivals and trick-or-treating to pumpkin decorating, haunted attractions and unique coastal events, there are Halloween activities for kids, families, teenagers and adults throughout SLO County.
Whether you're looking for Halloween events in San Luis Obispo, a family Halloween event in Atascadero, trick-or-treating in Pismo Beach, a haunted house in Paso Robles or something a little different in Morro Bay, October brings plenty of opportunities to get into the Halloween spirit.

Halloween in San Luis Obispo & SLO County
San Luis Obispo is a popular place to celebrate Halloween, with activities taking place throughout the city during October. Local organizations, businesses and community groups offer costume events, trick-or-treating, fall celebrations and Halloween-themed activities.
One of the larger Halloween-season celebrations in downtown San Luis Obispo is the annual Día de los Muertos event at Mission Plaza. The 2026 celebration is scheduled for Halloween Day, Saturday, October 31, from 11 a.m. to 3 p.m. The event will feature traditional altars, dancers, mariachis, face painting and other activities.
Día de los Muertos is a cultural tradition distinct from Halloween, but because the celebration takes place on October 31, it has become part of the holiday weekend calendar for many people visiting downtown San Luis Obispo.
Family-Friendly Halloween Events in SLO County
Families looking for Halloween activities for children will find several options around San Luis Obispo County.
One of the popular family-oriented Halloween events is Zoo Boo at the Central Coast Zoo in Atascadero. The 2026 event is scheduled for Friday, October 23, and Saturday, October 24. The evening celebration is designed to be family-friendly and includes Halloween decorations, games, costume activities, a haunted maze and treats.
For younger children who may not be ready for a traditional haunted house, events such as Zoo Boo offer a way to enjoy Halloween costumes and decorations without making the experience entirely focused on scares.
Pumpkins in the Park in Pismo Beach
Pismo Beach offers another popular family Halloween activity with Pumpkins in the Park.
The City of Pismo Beach has scheduled Pumpkins in the Park for Saturday, October 24, 2026, from 10 a.m. to 1 p.m. at Dinosaur Caves Park. Admission is free, and activities include pumpkin decorating, a costume contest, games, crafts and bounce houses. Pumpkin decorating is limited to the first 500 children, so families planning to participate may want to arrive early.
The Halloween fun continues downtown afterward with trick-or-treating from noon until 2 p.m. This makes Pismo Beach a convenient destination for families who want to combine a daytime pumpkin event with traditional Halloween activities.
Halloween Events in Atascadero
Atascadero is another community to watch when searching for Halloween events in San Luis Obispo County.
Zoo Boo at the Central Coast Zoo is one of the area's established Halloween celebrations, but other community Halloween activities can also take place throughout the city during October. Local event calendars list activities such as trick-or-treating and trunk-or-treat events as Halloween approaches.
Atascadero also hosts its annual Fall Festival earlier in October. While it is not specifically a Halloween event, the festival can be another seasonal activity for visitors planning an October trip to the area.
Halloween in Paso Robles
Paso Robles provides several opportunities to celebrate the Halloween season, including family activities and cultural events.
The Paso Robles Día de los Muertos Festival is scheduled for Saturday, October 24, 2026. The downtown celebration includes food, music, dancing, arts and crafts, vendors, children's activities and community altars.
For Halloween itself, Safe & Fun Halloween Downtown is an annual event that gives children an opportunity to trick-or-treat with participating downtown businesses. Event details should be checked with Paso Robles Downtown as Halloween approaches because schedules and participating locations can change.
Haunted Houses in San Luis Obispo County
For people searching for scary Halloween attractions rather than family festivals, SLO County has haunted attraction options.
Nightmare From Main Street in Paso Robles is a local haunted attraction located on 14th Street. It is one of the attractions to consider when searching for a haunted house in Paso Robles or a scary Halloween activity in northern San Luis Obispo County.
The Haunt in Atascadero is another Halloween attraction listed for the area. It uses an interactive, theater-style format and traditionally operates on selected dates during October.
Because haunted attractions frequently operate on limited dates and times, visitors should verify the current schedule, admission requirements and age recommendations before making plans.
Halloween in Morro Bay
Halloween takes on a distinctly Central Coast character in Morro Bay with the annual Witches and Warlocks Paddle.
The event brings costumed participants onto the water in kayaks and on paddleboards, creating a colorful Halloween spectacle around Morro Bay. The event is scheduled for October 2026.
The event is particularly different from traditional Halloween celebrations because it combines costumes, outdoor recreation and the Morro Bay waterfront. Visitors who prefer an outdoor activity to a haunted house may find this event an interesting addition to their Halloween weekend plans.
Halloween Activities in Grover Beach and Oceano
The southern portion of San Luis Obispo County also gets into the Halloween spirit.
Grover Beach has an annual Trunk or Treat event scheduled for October 30, 2026, at 16th Park. The family-oriented event provides an alternative to traditional door-to-door trick-or-treating.
Oceano is also scheduled to host a Trunk or Treat event in the area of 17th and Beach Street. Community trunk-or-treat events can be particularly appealing to parents looking for a contained environment where children can collect candy while showing off their costumes.
Halloween and Fall Activities Along the Central Coast
Halloween activities in San Luis Obispo County are not limited to October 31.
Throughout the month, visitors can find pumpkin patches, fall festivals, seasonal decorations and other autumn activities. One particularly recognizable seasonal tradition takes place in Cambria and San Simeon, where scarecrows are displayed throughout the two coastal communities during October.
For visitors who prefer daytime activities, a trip to the coast to see the scarecrows can be a fun way to enjoy the Halloween season without attending a nighttime event.

Family-friendly options include pumpkin decorating, costume contests, trick-or-treating, trunk-or-treat events, children's haunted houses, fall festivals and Halloween activities at community parks.
