Diver and Boat Readiness

Ask to see the operator's registration, safety brief, boat lifejackets, maintained equipment, emergency oxygen and communications plan. Carry an SMB and computer, use a buddy and remain within certification; do not follow cave or wreck imagery into overhead environments. In San Andres and Rosario waters, avoid busy boat corridors and wildlife-interaction tours that bait or handle animals. Santa Marta's trade winds, upwelling and Tayrona no-swim beaches need day-specific assessment.

Remote Pacific Threshold

Malpelo requires advanced certification, at least 35 logged dives, a locator, light, knife and SMB, daytime escorted dives and approved liveaboard access; operators may ask for more. Gorgona visits also require park-authorized transport and site restrictions. Strong currents, cold thermoclines, sea crossings and evacuation delays materially elevate risk. Freedive depth work needs a dedicated safety buddy/coach, not a casual snorkeling companion.

First contact local emergency services for a life-threatening event, provide oxygen and qualified first aid where trained, and ask the operator to activate its emergency action plan. Then contact DAN or your insurer for dive-medicine advice and authorized evacuation coordination. Hospitals and recompression availability differ by coast and island; neither Malpelo nor Gorgona should be assumed to have on-site hyperbaric treatment, and limited regional transport or weather may delay extraction. Before departure, obtain the exact receiving hospital, nearest functioning chamber referral, transport plan, operator satellite communications, emergency oxygen supply and insurance coverage. Check the Colombian Ministry of Health for municipality-specific yellow-fever risk and any required certificate.

Five different protected-area frameworks require particular care: PNN Corales del Rosario y de San Bernardo, PNN Tayrona, PNN Gorgona, PNN Old Providence McBean Lagoon and SFF Malpelo. The wider San Andres/Providencia region is influenced by Seaflower marine conservation and CORALINA management. Use designated sites, park-approved guides and existing moorings; do not anchor on reef, feed animals, touch coral, remove shells, enter closed turtle nesting areas or use prohibited disposable plastics. At Malpelo, the park bans single-use plastics and prohibits wildlife interference; island landings are not visitor activities. Gorgona's humpbacks and Providencia black crabs are protected wildlife, not interactive attractions.
