How to unlock the Fearless or Stupid achievement in Far Cry 3 - Definitive Guide
I believe you get the deep dive fairly early in the story, after the cave mission.
Here is my Solution for this Achievement.
The easiest Way is, go to a Beach / Water then use a Deep Dive Injection and dive into the Water and swim forward. For fast swimming push the Left Stick.
After a 60 Meter dive, the Achievements pops up.
Regards
So if you dive there you get the Achievement for sure and it also means if you want all Relics you have to do it anyway and automatically get this Achievement also.
Dive more than 60m (Single Player only).
Quite easy to unlock once you have unlocked the Deep Dive Injection, Just swim, boat or jetski into deep water (Shows as dark blue on the map) and then use a Deep Dive Injection and dive down and keep swimming, you can swim faster by using LS, Once you’ve reached a depth of 60 metres the achievement will unlock.

Use deep dive syringe to swim to 60M and bleep bloop

This is the best and fastest way to obtain this achievement, if you want to you can get the Deep dive Syringe, but it is not needed! On the South East side of the Island you will see somewhat of a gulf and in that gulf there is a little Dark spot.
Coordinates are around X:754.5, Y:655.2 (upper right hand corner of the map pause screen)
Once you get to that spot just swim down until you unlock the achievment.
Note: You will die, but don't worry you don't lose anything in this game for dying.
Make sure to grab the Relic because even though you die you still get to keep it!

It's not necessary to use any potions, just swin fast to the bottom and then back up the same way. There's a relic in there to be picked up as well.
Once you can craft the syringe, do so by collecting the necessary leaves.
Head to these coordinates: X:754.9, Y:655.0 (there will be an artifact at the bottom of this deep hole)
Stab yourself with the syringe and take the dive downwards. The trophy will unlock by the time you hit the bottom and grab the relic.
You'll first need to play a few main story based mission to unlock the Deep Dive Syringe. Once this has been unlocked and you've made one with the required coloured plants (2 Blue and 1 Green), head towards the sea. You're now looking for an area with the darkest blue to it. Head to these coordinates for an area opened up early to you - X: 709.1, Y: 835.6.
Now equip and use the Deep Dive Syringe and dive down to the bottom. Your best bet here is to press to swim faster so that you don't drown. Once you've reached and touched the bottom of the sea, the achievement will unlock.
Search for a dark blue part of the ocean on your map (e.g. at the coordinates X: 709.1, Y: 835.6). These are the deepest parts of the ocean. You need to activate radio towers to uncover the map. After reaching such a point in the ocean you need to dive down until you hit the ground. Click the left stick to swim faster.
