Dives Waiting To Happen


I'm looking for six (6) divers so that I can do a half-boat charter onboard Ferox

I will work as a crew member, but I will give full attention to my 6 divers. I will do my best as a guide and I won’t rest until we are on land. I can help with improving your vegetarian food, but not with your chocolate on your pillow. In that case you are not the diver I want to guide.

Malpelo Island 2025

March 7th to 17th, 2025 — FULL
March 19th to 29th, 2025 — NEW TRIP
July 19th to 28th, 2025 — 2 spaces sharing a Queen bed
July 30th to August 8th, 2025 — 2 spots left
August 8th to 18th, 2025 — 3 spots left
More info

This is not a destination for fainthearted divers.

Strong current, big surge, and waves crashing on the sheer rocky island that you can only get on by climbing a 10-meter-long rope ladder hanging from a ramp that sticks out from the island. IF it’s calm.

Malpelo Island 2026

March 10th to 19th, 2026 — Open
