Before the hike:
Adapt the tour according to ability and conditions. If you have children with you, the trip will be best if you plan the trip according to their needs and not your own ambitions.
Plan your trip well and the experience will be that much better. Check the equipment before you go. It's devastating to arrive and find that the tent pegs and sleeping mat are still at home :-)
Make sure you have enough clothes with you for the trip and the weather forecast.
Remember toilet paper, mosquito repellent, a knife, flashlight, food and drink, and extra snacks, especially if you have children with you.
Pack smart. We easily pack too much with us and you want to carry as little as you can. If you are not sure what you should take with you, ask a travel-savvy friend or see DNT's packing list.
