If you are driving from Pune to Garva Agro Tourism you have the option of choosing from four different routes. The shortest route would be via Bhor however considering road condition, route via Kumbharli Ghat would be the best route to take.
Pune => Satara => Umbraj => Patan => Chiplun => Tari => Abloli => Garva Agro Centre
Pune => Surur => Mahabaleshwar => Poladpur => Khed => Chiplun => Tari => Abloli => Garva Agro Tourism Centre
If you are traveling from Mumbai the route is quite straight forward. You need to follow the NH 17 (Goa Route) uptil Chiplun and get off the national highway just ahead of Chiplun towards Velneshwar. Approximately 20 Kms from here you would find the road sign towards Abloli. Once in Abloli follow the road signs to reach Garva Agro Tourism Centre.
