A simple day route taking you up the longest (height wise) route possible. Starting at around 65 metres and heading up to over 1000 at the top.
The route takes you through some beatiful and exclusive sites on Snowdon, passing by waterfalls and old quarry building as well as some beatiful natural flora.
The route itself is not hard by mountain terms. I have only listed it as a Medium due to a few hands on points. The majority of the trail is a well laid footpath with steps. You will need a little stamina to get up to the top, but as its not the longest route you have the opportunity to take it slow and still do the tour in good time.
The last pitch before the summit heads quite steep over loose rock and dirt. There is no good route marking at this point and it gets a little hands on.
There is an affordable campsite a few kilometers north east of the trail start called "Llyn Gwynant Campsite" (http://www.gwynant.com/index.html). At time of writing the rates are around GBP10 per adult if you want to pitch a tent.
Even closer are the "Red Dragon Camping Pods" if you would like a little more luxury (of course with a little more cost). You can hire out a small hut, or the same company even let out a large cottage. (http://www.reddragonholidays.co.uk/camping-pods-in-wales.aspx)
Failing all else just drive up and down the road a little. There are a lot of campsites and hostels in the area.
