The Island of Destiny

The Green Lagoon strikes you as being an intriguing name and you suppose you might as well go with your instinct. You gaze at the map, which along the trail it lines points to three landmarks. They are:

1. Poison Snake Stream
2. Tree Tumblers' Grove
3. Zayasu Jagged Rock

Although you have no idea where you are in the jungle right now, the map seems to be easy enough to follow. It follows along the path of a river which you can hear rushing nearby. So, gathering your wits, you set off in search of this Green Lagoon.

You walk for a few hours and you keep checking back at your map to see how close you are to the first landmark. Now that you have a better idea of the ratio of the map, you'd judge you're about two thirds of the way there. But as you glance at the sky, you see that the sun is setting. Soon it will be night and you'll probably have made it to the first landmark by then.

So should you find somewhere to camp for the night? Or should you try and make it to this Lagoon as quickly as possible?
