The logo cannot be too wide as it will go on vertical DL brochures, it will have to be readable from a distance as it will go on the door sides of a white truck, it will also be used on uniforms on the back of shirts and on the website.
It's a fun activity and accessible to everyone. The river is a quiet river not much currant, it's not crazy rafting down the river.
The logo will have to deliver that image : fun, adventurous but still accessible to everyone, eco tour, close to the nature, in the middle of the jungle...
The logo will be text oriented, the wordings will have to be visible from a distance. The logo will also include an illustration/image of the 2 activities to support it but it doesn't have to be too detailed.
The font used can be a bit funky/dirty/destroy/grunge but it still has to be readable from a distance.
Emphasis on River Tubing & Rafting, Vanuatu can be smaller.
