Either by road or ship
For ship, is there any specific timing for that.
By road is the best option...
Timings of convoys are 6 a.m. 9 a.m. 12 p.m 3 pm and 6 pm
You can also hire private taxi if you want but you should leave as early as possible. Leave as early as possible because the vehicles have to pass Jarawa reserve area in convoys only
Government and private buses are there but condition of both the buses are same... There isn't any luxury bus available as per my knowledge. All the buses leave early morning starting 5:00 A.M.
