Choose an activity that attract you the most.(e.g. hiking, trekking, spelunking or even diving)
Search places that suits on the activity you chose. You must pick a place where it can provide your desire activity.
Look for an Itinerary. For those who were having a hard in making their own "maps" finding an itinerary can be very useful for you to have an easy travel.
Plan everything. To make sure that everything is under your control you can make a list of task that need to be done before the day of your trip. (e.g. reserving tickets or even a room in hotel, the vehicle that you will use)
Be a scout. Pack all the things that you will be needing for the entire trip, much better if you wont bring unnecessary stuff that you think you can live without.
Be time conscious. It is okay to arrive early rather than late. Why? because it can affect the entire plan of your trip. Being solate is a BIG NO! NO!
Be alert. When you are already at your destination, be aware of what's happening around you so you can avoid an interruptions like accidents.
Don't treat yourself as a tourist. Be good to locals living in the area, don't hesitate to ask them if you need help and be humble as much as possible.
Enjoy every moment. Look into the trip as if tomorrow will be the end of the world so you won't feel any regrets when you leave the place.
Be thankful. Thank God at the end of the day for keeping you away from harm.
