I’ve researched the specific base locations for these trekking and adventure groups. While many of these groups operate across the Sahyadris, their administrative offices or primary pickup points are usually tied to specific cities. Here are the location details for the groups you listed:
Mumbai & MMR Based Groups
These groups primarily organize pickups from Mumbai, Thane, Kalyan, and Navi Mumbai.
The Trekers: Based in Dahisar East, Mumbai (near Manav Kalyan Hospital).
The Trek & Trails Co: Head office in Mazgaon, Mumbai (near Dockyard Road). They also have a dedicated Pune support wing.
The Tour & Villa Culture: Located in Andheri West, Mumbai (D.N. Nagar).
The Climbscapers: Based in Thane; they focus heavily on Sahyadri and Himalayan treks.
Vasai Adventure Club: As the name suggests, they are based in Vasai/Virar region.
Trek India: Operates primarily out of Mumbai (centralized pickups).
Trekkers United: A prominent Mumbai-based group.
Unaad Bhatkaa: Based in Mumbai; known for offbeat Sahyadri explorations.
Yanam Travels: Based in Mumbai.

Pune Based Groups
These groups typically start their treks from Pune or Swargate/Shivajinagar.

TRAVOTIC HOLIDAYS: Headquartered in Kolkata, though they run pan-India tours.
For the others on your list (like THE AWARA TRIBE or Trail Buddy), they function as “Cloud Groups”—they coordinate via WhatsApp and pick up trekkers from multiple points (usually Dadar, Thane, or Borivali for Mumbai groups, and Hinjewadi or Swargate for Pune groups).
