Mammoth Lakes has one clearly confirmed municipal Halloween family party in 2026: a costume-and-games event at the ice rink. Elsewhere in Mono County, pumpkin season and mountain fall colors make good family day trips, although not every destination hosts a Halloween event.

Updated October 11, 2026. Confirm tickets, timing, parking and weather with event hosts. Some activities are fall outings rather than confirmed Halloween celebrations.

3 Halloween 2026 and seasonal outings in Mono County

1. Halloween Party and Haunted Ice Rink

Location: LA Kings Ice at Mammoth Lakes / Community Recreation Center
Dates: October 30, 2026
Time: 4–7 p.m.

City-run skating celebration with carnival games, costume contest and rentals while supplies last. Free for members, $5 for non-members; non-skating adults enter free. Food and cakewalk cost extra. View organizer or official listing.

2. Chalfant Big Trees Pumpkin Patch

Location: Chalfant Valley area
Dates: October 2026 pumpkin season
Time: Farm schedule varies

Pumpkins, themed decorations, games and mazes. Visit Mono County lists the farm as an October attraction, not a Halloween-night public festival. View organizer or official listing.

3. June Lake Leaves in the Loop — earlier fall festival

Location: June Lake Loop
Dates: October 9–11, 2026
Time: Program-specific sessions

Fall-color weekend with pumpkin activities, workshops and community gatherings. Distinct from Halloween festivities later in the month. View organizer or official listing.

Family itinerary

The haunted rink is the most specific verified family event for Halloween week. Bring warm clothing: Mammoth Lakes is high elevation and may see freezing weather in October. Chalfant is far to the southeast and should be planned as a separate drive.

Safety and accessibility

Do not assume a scheduled event is free unless the source states it. Verify age guidance for scary attractions and reservation requirements for trains or ticketed experiences. Wear warm clothes on mountain and coastal outings, and use marked crossings during downtown candy walks.
