Terrain
The walks at Elsey are on marked trails. The ones in Limmen and on Lorella are mostly off-trail. Some sections of these walks are fairly flat and straightforward but there are some longish sections of rock scrambling and a couple of short but sharp climbs. If you have never done this before, you may find this fairly difficult.
Vegetation
Much of the walking is through relatively flat, open woodland with a grassy understorey. Some short sections of grass may hide a broken rocky surface where you will have to be particularly careful. In 2021, we had one short section of very thick scrub we had to bash our way through. The vegetation can vary from year to year depending on when last burnt.
Generally 4-6 hours, not including breaks. A few days might be longer.
You need to carry up to 7 days food on the longest walk. Much less on the shorter ones. Day packs some days.
