For a 5–6 day Jain pilgrimage tour starting around May 27, 2026, these look like good options:

1. TourMyIndia

They list several Jain packages that match your duration, including Jain Pilgrimage Shikhar Ji Tour (06 Days), Jain Pilgrimage Tour of North India (06 Days), Jain Pilgrimage Tour Uttar Pradesh (06 Days), and Jain Pilgrimage Tour Karnataka/Tamilnadu (05 Days). ( tourmyindia.com)

1. Jain Routes

They have a 5 Days Shikharji & Panch Teerth Yatra, which is a strong Jain-specific option if you want a shorter packaged yatra. ( jainroutes.com)

1. Su-man Tours & Travels

They specifically mention that they conduct all Jain pilgrimage / Shikharji tours and do tailor-made Jain religious tours, so they may be able to arrange a departure close to May 27, 2026 even if the standard listing is not fixed. ( su-mantours.com)

Best fit for your dates:

• If you want a fixed 6-day package, start with TourMyIndia. ( tourmyindia.com)
• If you want a very Jain-focused 5-day yatra, try Jain Routes. ( jainroutes.com)
• If you want a custom departure on May 27, 2026, Su-man Tours is worth contacting for a tailor-made plan. ( su-mantours.com)

If you want, I can next help you narrow this to Shikharji, Rajasthan, South India, or a Pancha Tirth route.
