Why spend Halloween at Reload Saturdays
Reload Saturdays is Trinity's weekly 18+ EDM night, and on Halloween it gets the full treatment. Rise Over Run hold the residency and play EDM, electronic music and dance-floor hits from the moment doors open. The main room is wrapped in 360° LED walls, so the visuals move with the drops, and the sound system was built for electronic music.
Because entry is 18+, it is one of the few Halloween parties in Seattle where college students and anyone under 21 can get in. If you are new to the 18+ scene, our guide to 18+ clubs in Seattle covers how these nights work.

The costume contest
Come in costume. Halloween at Reload Saturdays includes a costume contest with a cash prize, so the effort you put into your look can pay off before the night ends.
A few ideas that work on a packed EDM dance floor:
Glow and LED costumes: light-up accessories, neon face paint and reflective fabric look sharp under the LED walls.
Cyber and futuristic looks: metallic fabrics, visors and robot or android styling suit an electronic music night.
Glow-in-the-dark skeletons: a Halloween classic that reads clearly in low light.
Group costumes: coming with friends? A matching theme stands out in a crowded room.
You will be dancing for several hours, so choose something light, breathable and easy to move in. Skip bulky props and wide wings that take up space in a crowd, wear shoes you can stand in until 3 AM, and keep your ID somewhere you can reach it quickly. The listed dress code is smart casual, dress to impress, so build your costume on that.
Tickets and entry
Advance tickets are recommended. Halloween is one of the busiest nights of the year, and buying online means you are not relying on door availability. Walk-up tickets are sold at the door while capacity allows, and the door accepts cash, card and mobile wallets.
Entry is 18+, and you need valid ID to get in. Guests 21 and over can buy drinks with valid ID. Before you head out, read The Rules for ID requirements and venue policies, so there are no surprises at the door.
VIP tables
