Can I use my voucher for backpack offloading and for renting gear?

The voucher you have from Indiahikes can be used for backpack offloading.

Once you select the offloading option on your dashboard, it takes you to a page where you can apply the voucher and make the payment.

NOTE : You will be able to choose backpack offloading only after you make the payment for the trek.

However, you cannot utilize Indiahikes vouchers for rental purposes.
