From Visakhapatnam, catch the 1 Vishakapatnam - Kirandul Passenger (1VK) having Reserved First Class & Sleeper Class accomodation. 1 VK departs Vishakapatnam at around 06:45 am and reaches Jagdalpur by around 05:30 pm
From Hyderabad, you have to reach Bhadrachalam first and then drive down close to 250 Kms on the single -laned NH 212, via Konta & Sukma to reach Jagdalpur. Road conditions are bad,and be prepared for frequent checks by the law enforcement authorities. Your vehicle of choice for a trip to Jagdalpur should ideally be a vehicle having a high ground clearance, and SUVs like the TATA Safari & Ford Endeavour fit the bill perfectly.
From Raipur (Capital of Chhattisgarh state), the road to Jagdalpur is good enough. You have regular overnight non-a/c sleeper buses running between Raipur/Bilaspur & Jagdalpur.
Check out the Anthropological museum (Located about 3 Kms from the city centre - closed on Sundays); there is also a big lake within Jagdalpur, with boating facilities. Take a walk down the Sanjay market area. No public transport in Jagdalpur; you can hire cycle-rickshaws though.
There is another temple (dedicated to Goddess Danteshwari) located at Dantewada, about 60 Kms from Jagdalpur, on the way to Bailadila.
Mahua - the traditional Bastar drink. Have it strong or mix it with water or soft drinks.
If not on your own conveyance,and intend to get to Raipur, catch one of those numerous sleeper non-a/c buses to Raipur.
If you intend to go to Vishakapatnam, catch the return 2VK passenger that arrives at Jagdalpur at around 09:30 am (Daily service)
If you intend to go to Hyderabad/Vijayawada, start early, catch the NH 212 to Bhadrachalam, and onwards to Hyderabad/Vijayawada.
BEWARE OF NH-16 TOWARDS NIZAMABAD - Never even think of going west, towards Nizamabad (In Andhra Pradesh). Maps show the existance of NH16, linking Jagdalpur & Nizamabad via Gidam,Bijapur,Madded & Bhopalapatnam, but in reality, the road (NH-16) starts gettting bad to worse from Bijapur onwards, and abruptly comes to a halt at Bhopalapatnam. Lack of a bridge across the Indrawati near Bhopalapatnam is the main culprit.
So, if you are planning to get to Hyderabad via Bhopalapatnam & Warangal (NH - 202) - don't even think about it!
