What can’t I bring into Boston Calling 2025?

Boston Calling Music Festival 2025 enforces a strict list of prohibited items at the Harvard Athletic Complex to ensure safety and smooth operations. You cannot bring glass containers of any kind (bottles, jars, etc.), as they pose a risk in crowded areas—this includes perfumes or glass water bottles. Drones, lasers, and any remote-controlled devices are banned due to security and airspace regulations around the venue. Large bags exceeding A4 size (30cm x 8cm x 21cm) are also prohibited; only small clutch purses, fanny packs (6” x 9” or smaller), or clear plastic bags (12” x 6” x 12”) are allowed, and all will be searched at entry.

Other no-gos include weapons (obviously), aerosol cans (like spray sunscreen), outside food or drink (except reusable water bottles or hydration packs, which must be empty on entry), and professional cameras or recording equipment without prior approval. Backpacks with multiple pockets are out, but single-compartment hydration packs with up to two additional pockets are okay.

This policy helps manage the 40,000+ daily attendees and aligns with feedback from past years about crowd flow. A full list is available on bostoncalling.com—review it to avoid delays at the gate, where confiscated items won’t be returned.
