Hi guys, i was just wondering which part of the earth would you guys not suggust to go on hiking? maybe because its extremely dangerous?

In my country Singapore there are only 2 places that could be use for hiking and the dist is about 6km. There’s not much to see and the only animals i could see are the monkeys and snakes.. nothing dangerous.
I know in Malaysia you gotta be careful of black widows.

In bear countries, they got black and brown bears?

What other hiking countries? places?
