Triund is one of my favorite trekking destination in Himalayas. The trek from Triund to Snowline is a bit difficult but can be done easily with a lot of patience. You can easily find tents for overnight stay. But, I will suggest you to go with a guide on any Himalayan trek. They will arrange tents and food for you both.
Hey, camps are very easily available at Snowline cafe. The cost is 300 bucks per person. It is completely safe there at Snowline, local people of Snowline cafe will guide you completely. for any further details and queries or itinerary, you can contact me I'll provide you with the same! thankyou.

Ask someone who has recently gone to this trek because this trek was shut and is supposed to reopen in October and not really sure if there will be these facilities when it reopens.
