Weekend plan near Banjar Valley: Which nearby spots to hit?

I’m heading to Banjar Valley for a quick weekend escape and want to make the most of the surrounding area. The Great Himalayan National Park is just 20 km away, and Shringa Rishi Temple is only 5 km from the valley. Chehni Kothi is about 10 km out, while Tirthan Valley lies roughly 35 km away. Which of these spots would you recommend for a short visit, and how long should I budget for each? Also, is there any particular route that’s best for a quick round‑trip from Banjar?
