Luggage and bags:
You will need a decent rucksack if you intend to do much walking here and preferably one with air flow at the back as it can get hot.
Make sure you have plastic bags also to put any maps and valuables in just in case you get caught in a down pour. Even in a rucksack things can get very damp
Clothing/Shoes/Weather Gear: Decent boots are a must.
As you are in the mountains, the weather changes a lot.
It may be hot and sunny for the first couple of hours of your walk then rain very heavily for the rest of the day. Pack some decent waterproofs!
If you do forget anything though, there is a decent little shop in the town which I found reasonably priced
Toiletries and Medical Supplies: Put a bit of loo roll in your rucksack - just in case!
Photo Equipment: Camera/camcorder with plenty of memory cards/film/tape!
Camping/Beach/Outdoor Gear: You will need a decent map (the one for sale at Ecoturs is good) and a compas as you can't rely on following just the red markings alone as they can be few and far between or (worse) lead you along the wrong path!
Miscellaneous: I am putting together a web site with details of lots of walks - I will post the URL when it is complete!
Luggage and bags:
Rucksack for picnic lunch and water bottles
Clothing/Shoes/Weather Gear: Good hiking shoes or trainers for lower paths
Rain wear if you are in the hills about 3pm when it thunders!
Toiletries and Medical Supplies: Sun block and hat
Photo Equipment: Plenty of memory cards for the digital :-))
(I have my reputation to think of ;-) )
Miscellaneous: Invest in a map indicating the trails in the area and the time needed. We were given one by our tour company and was invaluable - they are available in the local shops too.
Info boards are available at the entrance to the park regions - see sports tip - but they don't fit in your rucksack!
Region B is up near the ski - lift end of town - near our Hotel and this board was for region C - where we started the hike to Monte Tranquillo and the sanctuary.
