Hi everyone! I’m planning a 2-day trip with friends and need some help with travel guidance and tips for the following itinerary: 1. Day 1: Starting from Pune early in the morning. Heading to Kalsubai (planning to trek there). After Kalsubai, we’ll travel to Nashik and stay overnight. 2. Day 2: Morning: Leaving from Nashik for Harishchandragad. Planning to complete the Harishchandragad trek the same day. After the trek, we’ll travel directly to Mumbai Best routes or transport options for each leg of the trip?
