Trevor wants a shipment of diamonds taken from Merryweather guards in Paleto Bay. You steal the case, get to the jetty and boat it south to the drop-off in Cassidy Sound.

Before you start

Bring a fast car, since you start on foot and the diamonds are across town.

A rocket launcher is the best answer to the helicopter that joins the chase.

Wear body armor, because the guards use advanced rifles.

Diamonds are for Trevor walkthrough

Steal the diamonds

Drive through Paleto Bay toward the marker on the back streets. The diamonds sit in a yard behind some buildings, guarded by Merryweather who carry advanced rifles. Park a short way off, use the walls and parked trucks as cover, and take the guards out before you move up. Pick up the diamond case from the yard once nobody is left shooting.

Take them to the jetty

With the case secured, follow the road to the Paleto jetty on the coast. Keep driving rather than stopping to fight anything on the way. The road winds along the shore, and the marker leads straight to the jetty where Trevor’s boat waits. Leave the car at the dock and walk out to the boat.

Get in the boat

Trevor texts that reinforcements are coming by sea and by air and asks you to bring the boat back in one piece. A helicopter arrives over the bay, and a rocket launcher from the weapon wheel handles it well. Shoot it down from the jetty, or ignore it and hurry aboard. Take the driver’s seat and head out into the bay.

Run the coast to the drop-off

Steer south along the coast toward Cassidy Sound. Dinghies full of Merryweather guards come after you, so stay on the open water and keep your speed up. A partner can shoot back while you drive. Do not ram the shore or rocks, since the boat has to arrive in one piece. Hug the middle of the bay and follow the marker around the headlands.

Deliver the boat

The drop-off is under the Cassidy Creek bridge, in a small cove past the shoreline. Slow down as you approach and steer in gently rather than beaching the boat at speed. The diamonds and the boat count as delivered once you stop in the marker.
