Mastic Trail: Visitor and Heritage Guide

What the trail protects

The Mastic Trail crosses the largest contiguous area of untouched old growth dry forest on Grand Cayman, and it is home to a wide variety of indigenous animals and plants.

Read that description carefully, because each part of it is doing work. Old growth means forest that was never cleared. Contiguous means it has not been cut into fragments by roads and development, which is what usually happens to woodland on a small and intensely developed island. On a landmass this size, an unbroken stand of original forest is not a formality. It is the exception that survived.

Who protects it

The National Trust for the Cayman Islands was established in 1987 as a charity dedicated to protecting biodiversity, local wildlife and critical habitats, and to preserving the islands built heritage. The Trust holds and manages sites rather than merely campaigning about them, which is why this forest still exists in the form it does.

The blue iguana

The Trust also runs Blue Iguana Conservation, working with Grand Cayman largest endemic land animal. An endemic species is one found naturally nowhere else on earth, and the blue iguana is the territory clearest example: a heavy, ridged, genuinely blue lizard that exists on this one island and nowhere beyond it.

Species conservation and habitat conservation are the same project here. The forest is what the iguana needs, and the Trust protects both under one roof.

Visiting

Treat the trail as a walk through protected habitat rather than a scenic footpath. Dry forest is hot, the ground is rough limestone, and the interest is in what lives there rather than in views. Sturdy shoes, water and insect protection are the minimum, and going with a guide will show you a great deal you would otherwise walk straight past.

The Trust offers tours and can be booked in advance, which is the better option on a trail where knowing what you are looking at is most of the value.

Practical

• Wear proper shoes. This is limestone underfoot, not a boardwalk.
• Carry water and insect protection, and go early rather than in the afternoon heat.
• Book a guided walk through the National Trust if you want to understand what you are seeing.
• Stay on the trail. The point of the place is that it has not been disturbed.
