camping
Snowdonia has a large number of campsites and finding a pitch is rarely a problem. Facilities range from the most basic with nothing more than a drinking water tap in the corner of a small field, up to plush "Holiday Parks" with electric hook-ups, laundry facilities, on-site restaurants and night-time entertainment. See the relevant town and village articles for listings.
backcountry
Wild camping is possible but remember that in Snowdonia, like other UK National Parks, the vast majority of the land is in private ownership. Generally at low-level and/or in the busy tourist season, it's better to stick to "official" campsites. On higher ground, in less popular areas, or out of season, you're less likely to encounter any problems. Use your discretion as to what constitutes an appropriate site, and where possible gain the permission of the farmer or landowner. Please follow the guidelines in Leave-no-trace camping.
hostels
The Youth Hostels Association YHA (http://www.yha.org.uk/) has a dozen hostels in, or close to, the National Park. Most of these are located in the northern part of the park, around Snowdon itself. Only Kings hostel, near Penmaenpool and Ffynonwen hostel, near Bala cover the southern or eastern areas of the park.
There are also numerous private hostels, especially in the popular outdoor activity centres such as Llanberis, Betws y Coed and Bala.
