More ways to explore the area's outdoor wonders
The cold hits behind your neck the moment you step off the wet grass and toward the fissure. Wind carries a clean, mineral scent and the water in front of you is the clearest you have ever seen — a glass ribbon threading through a cracked landscape. Guides fit drysuits with practiced hands, wrists and neck seals checked twice, and you slide into the surface like a diver into a cathedral.

Bring thermal base layers
Under a drysuit, long thermal underwear and thick wool socks are essential to stay warm; cotton will make you cold if it gets damp.
Hydrate and eat beforehand
You’ll be in the field for around 4–5 hours and should eat a solid breakfast and hydrate before pickup; there’s little time to eat between gearing and entry.
Book the earliest slot for calmer conditions
Morning tours often have less wind and smoother water, which makes gearing and underwater photos easier.
Follow size and medical limits closely
Operators require height, weight, and medical forms; provide accurate data and consult your physician if over 65 or with cardiovascular/spinal issues.
Thermal base layer
A wool or synthetic layer under the drysuit keeps core temperature stable in cold water.

Thick wool socks
Wool socks help insulate feet inside drysuit boots and reduce heat loss.

Prescription mask or contact lenses
