Indiana State Sanatorium Second-Night Investigation
Haunted Nights also lists a second Indiana State Sanatorium event for May 2, 2026. It uses the same overnight structure: early check-in, a venue tour, then investigation access through the sanatorium buildings and tunnels until 4:00 AM.
Event Briefing
Useful for travelers trying to line up a specific weekend date at a venue that offers enough scale to justify repeat nights.
A second active Indiana sanatorium night for travelers comparing back-to-back dates at the same tunnel-heavy complex.

Planning Notes
- Treat this as the fallback or alternate date if May 1 becomes harder to book.
- The venue format mirrors the first night, so the same gear and arrival recommendations apply.
- Check the source page directly before booking because multi-night event weekends can change availability quickly.
What Changes During This Window
These are the reasons this event is worth scheduling around instead of treating it like a generic date label.
This duplicate weekend date shows the sanatorium is being run as a two-night investigation block.
The venue keeps the same mix of buildings, tunnels, and medical-institution history that drives its paranormal reputation.
Back-to-back nights like this are useful if the first date starts to sell through faster than expected.
