Friend day pass for youth discount

I want to ask if my friend day pass for youth is eligible for reduced price in grindelwald adventure package?

Welcome to the SBB Community. We are a customer support forum run by volunteers.
A hello is always appreciated 🙂

No. Day passes do not grant additional discounts, no matter which day pass.

The Grindelwald adventure package is anyway an offer from a private provider.

Kind regards,
Roland
