Beautiful B&B with sea view in Manarola.

Ostello Tramonti

Is actually in biassa, not any of the five towns, but is accessible by bus from la spezia and riomaggiore. a word of warning: the last bus up the mountain runs at about 8pm, and you don't want to hike up in the dark.

Above corniglia, offers accommodation for about €60 per room.

(http://www.baranin.com/). provides rooms with b&b treatment and apartments in manarola.

Cinque Terre Holidays

Hostel in riomaggiore. €40/person, but these are rooms with a view! high up on a hill with a stone balcony overlooking the sea in front and a terraced mountainside on the side. be warned that this hostel has gotten very mixed reviews on review sites.

Campgrounds

campgrounds
 

There are a few campgrounds where you can rent a tent with two beds and linens for very low prices. Note that none are inside the national park area but quite a few can be found just to the north of the park in the touristy but pleasant town of Levanto.

campgrounds
Camping Aqua Dolce

Near the town center and about 200 meters from the beach.

campgrounds
Pian di Picce and Albero 'd Oro

Are situated next to each other a bit more inland, at about 1000 meters from the beach but closer to the railway station at about 200 meters.

campgrounds
 

Other campsites can be found south of La Spezia and further north around Deiva Marina. Levanto is a better option though because it is serviced by the park-run train service connecting all five villages as stated earlier.

It's advisable to try to book in advance when arriving in late June, July, August since these sites tend to fill up quickly during that period. Many hotels, including the hostel, book up in months in advance.
