HI Phil

Parking is quite easy for the waterfalls - to get to the Barranc de Caramella just take the Mont Caro road and just after the dry canal take the first road on the left.  You will eventually come to a t-junction with a rabbit farm opposite, take the left and then follow to the right around the farm.  The road now gets pretty bumpy and narrow but keep on , over the cattle grid and down to the parking area at the hunting lodge.  It is just a short walk from here along the barranc or taking the path on the right to the pools and falls where you can follow the path alongside them.  How far it goes I don't know as at one point I needed to carry the dog as she does not like getting near water and it appeared necessary to go through the water to follow the path so I didn't go any further.  In fact the next time I was there I found the path went around the water on the left, but was well hidden in the undergrowth and I was short of time to follow it.   I just find that during the summer, rather than this time of the year it is a nice walk to do as I can swim in the pools on the way, plus the fact that the scenery is stunning.

Tosca is a delightful spot where the waters come pouring down out of the mountainside (you will see Tosca water on sale in the shops).  To get to Tosca just follow the Alfara de Carles road from Roquetes and the turn is on the left about 3k before Alfara.  There is some delightfuly scenery here as well, with the remains of hermitages dotted around.

Good walking !!
