Fuel up on a hearty local breakfast (parathas / omelette / tea) at a roadside dhaba or hotel in Aut/Bhuntar before beginning the mountain drive; most dhabas open by 7:00–8:00am.
Scenic 1.5–2 hour drive along river Uhl with pine-clad slopes and small hamlets — the road winds up into the Barot valley and is photogenic with several easy pullouts for photos.
Visit the trout farm and enjoy a calm riverside walk; it's a peaceful spot to stretch legs and photograph the valley — trout farm visits usually possible between 9:00–17:00 but check locally.
Try a Himachali thali or freshly cooked trout at a local homestay/dhaba near the river — home-cooked food is the highlight and most places serve lunch from ~12:00–15:00.
Explore Barot’s quiet lanes, check the small reservoir and forested trails (gentle 1–2 hour walks suitable even in Diwali clothing); trails are open daylight hours, avoid dusk in remoter tracks.
Stroll to the Jibhi waterfall and the small village temple; Diwali evening often has local pujas and lamps — timings vary but village pujas typically begin around sunset (6:00–8:30pm).
Enjoy a warm Himachali dinner at your homestay or a local café—homestays often serve seasonal specialties (dal, rajma, kadhi, local vegetables) and are ideal on Diwali night.
Drive up to Jalori Pass (approx 45–60 minutes). Note: the pass is high-altitude and the access road is often open May–November but can close early with snow — check local conditions the morning of travel.
Short steep hike (~30–60 minutes one way) to the pristine Serolsar (Serol Sar) lake — a tranquil high-altitude lake with a small temple nearby; lake area is typically accessible daylight hours (sunrise–sunset).
Visit the small Bhutnath temple above the lake and spend time photographing the alpine scenery and glacial-fed waters; temple and lake area are popular mid-morning to afternoon spots.
Enjoy hot thukpa, rajma-chawal or local curries at a roadside dhaba near the pass — dhabas near passes tend to operate 9:00–17:00 but are seasonal, so carry light snacks just in case.
Scenic descent into the Tirthan Valley; the drive takes about 1–1.5 hours and brings you to riverside Gushaini, the entry point for many Tirthan activities.
Settle into your riverside homestay and take a mellow walk along the Tirthan River — ideal to spot trout pools and enjoy the valley’s quiet before Diwali night.
Many homestays host small Diwali gatherings or will let you light diyas by the river; connect with hosts earlier in the day to learn exact timings (local pujas often start at sunset).
Take a guided 1.5–2 hour nature walk into the Great Himalayan National Park buffer/nearby trails — GHNP trails and permit offices are open during daytime hours (usually ~9:00–16:00); book a guide/permit via your homestay in advance.
Begin the drive back to Bhuntar/Aut (approx 2 hours). Plan for traffic and allow extra time if you have onward travel (flight/train) from Kullu-Manali or Chandigarh.
Finish the loop and prepare for onward travel — if you have a late evening flight or bus, consider a short walk in Bhuntar market for souvenirs and snacks.
