I learned from experience that it is always worth to carry a flashlight with you. Even if you do not plan to trek after dusk. If you get in any situation where you have to face dark, nothing will give you peace of mind more than a charged flashlight. It is useful to explore some interesting place you might come across too, such as smal caves, crevices and some abandoned underground shelter or farmhouse. I use a Maglite double d-cell flashlight as part of my equipment. This particular model balances finely between weight and lighting power.
Something I never trek without, is my wrist-top computer. The below model is the Suunto X-lander, a 'watch' which will never let you down. It has a compass, barometer, altemeter and many other functions, among which surprisingly enough there is a basic clock. Eventually you will make reference to many of it's functions. And the compass function is truely practical and accurate.
Many consider a small knife as essential. I definitely agree with this. However, although I am a fanatic of large knives including fancy hunting knives and machetes, you will not need such stuff while trekking. All you will need is a small pocket knife to cut down possible obstacles and maybe to eat a fruit or two with. A pocket knife of small size will also keep you in good terms with the authorities. Be realistic, you will never need a 12-inch blade hunting knife while trekking in Malta.
When trekking coast-side, you will need to climb or descent very sharp surfaces, if you do not fancy yourself as a stigmatee be wise and equip yourself with a pair of synthetic leather gloves. They are flexible enough to avoid you nasty scratches and at the same time to let your hands adapt to the surface you are trying to master. Try to chose a pair of gloves which are water proof.
A box of matches and a cheap-ass zippo-style lighter would make your day if for some unfortunate reason you need to light a fire to keep you warm at night. The zippo-style lighter is the best common source for flint sparks. If you need to light a fire you will never regret carrying thes two simple items with you.
As a precaution I always carry with me a telescopic baton as a deterrent. I've been unfortunate enough to encounter guard dogs or hunting dogs too often while peacefully minding my own business trekking. I am not advocating violence against animals, since even the swishing noise the baton makes while extending will scare the animal off. Do not use this tool on the animal as it is absolutely not humane (this thing hurts big time). A hit on a nearby rock will signal the animal that you are not scared of it and it will rapidly flee off the scene.
Half of the pleasures in trekking are the memories that come with it. Always carry a digital camera with you to capture that breathtaking scene or that steep cliff you were able to master.
As part of my package I normally also take with me some food and drink supplies. As a rule of thumb I take 3 litres of drinking water for a planned six hour trek. As for nutrition I opt for some fruits and a packed lunch. You do not need to go over the top on these since a heavy stomach will hinder your progress. Find a balance.
A couple of other items I did not mention are some sun-shades and your mobile phone. Do not overlook these two items.....NEVER!
Trekking is all about balance, mainly...... weight versus functionality
