How we vet our hosts
We don't use words like "guaranteed" or "worry-free." We use specifics. Here's exactly what we check, what we require, and what you can expect from every adventure on ZeroCrowds.
Every host is vetted. Here's what that means.
Before a host joins ZeroCrowds, we verify their credentials personally. Not a checkbox form — a real review. We check certifications, talk to references, review safety records, and confirm insurance. We've said no to more hosts than we've said yes to. That's the point.
Certifications
Every host holds verifiable, current certifications for their activity. AIDA for freediving. IYT for sailing. Relevant national and international qualifications for every discipline. We check expiry dates, issuing bodies, and scope.
Insurance
Every host carries professional liability insurance that covers their specific activities and group sizes. We confirm coverage details and validity before any adventure goes live.
Safety protocols
We review each host's safety plan — emergency procedures, communication protocols, backup plans for weather and conditions, and evacuation routes. These aren't templates. They're specific to the activity, location, and group.
Equipment standards
All safety equipment is provided by the host and inspected before each adventure. We confirm equipment type, condition, maintenance schedules, and replacement policies.
First aid certification
Every host has current first aid certification appropriate to their activity. For remote and water-based adventures, this includes wilderness first aid or equivalent.
Experience and track record
We review each host's professional history — years of experience, teaching record, competition results where relevant, and references from past travelers and peers.
Small groups aren't a perk. They're a safety standard.
Every adventure is capped at 6-8 travelers. That's not a marketing decision — it's a safety one. Smaller groups mean:
- Your host can monitor every person individually
- Equipment checks are thorough, not rushed
- Communication is direct, not relayed through assistants
- Emergency response is faster and more effective
- Environmental impact on the destination is minimized
Honest requirements. No surprises.
Every adventure page lists specific physical requirements, experience level expectations, and what you'll need to bring. We ask hosts to be direct about what an adventure demands — not to discourage you, but to make sure you're prepared.
Experience level. Beginner, Intermediate, Advanced, or All Levels — with specific detail for that activity.
Physical requirements. Specifics like "able to swim 200 meters" or "comfortable hiking 6 hours with a pack."
What to bring. A detailed list so you're fully prepared.
What's provided. Every piece of equipment, gear, and safety item included.
What happens on the ground
Your host is responsible for the adventure — instruction, route decisions, pace, and safety calls. They carry emergency equipment, have communication with local emergency services, and know the terrain, water, or airspace they're operating in.
Communication
Hosts maintain contact with local emergency services and carry appropriate communication equipment for their environment — VHF radio at sea, satellite phone in remote areas, cell coverage confirmation in accessible areas.
Equipment
All safety equipment is inspected before each adventure. For water activities, this includes emergency oxygen and flotation devices. For mountain activities, this includes weather monitoring and route assessment.
Weather and conditions
Hosts make the call on conditions. If weather or circumstances make an activity unsafe, plans are adjusted. Your safety comes before the schedule.
Medical
Hosts know the location of the nearest medical facilities and have evacuation plans specific to their location. For freediving, the nearest hyperbaric chamber is identified in advance.
Your part
Safety is a shared responsibility. Here's what we ask from you:
Be honest about your experience. Your host designs the adventure around the group's level. Overstating your experience doesn't help you — it puts the group at risk.
Follow your host's instructions. They know the conditions, the equipment, and the terrain. Trust their calls.
Carry travel insurance. We require all travelers to have travel insurance that covers their specific activity.
Ask questions. If you're unsure about anything — fitness requirements, equipment, conditions — ask before you book.
Small groups by design. Better for the places you visit.
We don't have a sustainability badge. We have a sustainable structure. We're not B Corp certified, we don't run a carbon offset program, and we haven't completed a formal sustainability audit — we won't claim them until they're real. What we do have:
Local hosts, local benefit
Every host lives and works in their destination year-round. When you book, the money stays local. You're supporting a guide who has a stake in protecting the place they love.
A tree planted with every booking
Every booking triggers a tree planting. It's not offsetting — it's a start. We track every tree.
Carbon footprint calculated
We calculate the carbon footprint of every adventure. We share it transparently. We don't claim to offset it — we're honest about what we measure and what we're working toward.
Environmental practices verified
We review each host's environmental practices — waste management, wildlife interaction protocols, local sourcing, and community engagement.
Questions about safety?
We answer every question directly. If you want to know about a specific host's certifications, a specific adventure's safety plan, or anything else — ask. We'll give you specifics, not reassurances.
