If you show your reader what happens, you’re more likely to keep him interested in your writing. This goes for travel writing, books, novels, and more.
Use action words and avoid passive verbs.
Try this exercise:
Instead of writing…She suddenly saw the snake out of the corner of her eye. Say…Eyeing the snake out of the corner of her eye, she ran inside and slammed the door behind her.
Instead of…Sally was very tall. Say…Entering the doorway, Sally had to duck so she didn’t hit her head on the frame.
Bring the reader into the picture with you.
