Water purification tablets or a portable water filter: While treated bottled water might be available at certain points, these can be backups for refilling your water bottle from streams.
A headlamp: For early morning starts or navigating dimly lit pathways.
A pair of hiking poles: Provides stability and support on uneven terrain, especially helpful during descents.
Cash in small denominations: While credit cards are not widely accepted in remote areas, you might need cash for local shops, tea stalls, or unforeseen expenses.
