Brief ideas on what you might need for a walking or weekend event - it is not comprehensive. -For guidance please contact the leader (or phone number on the home page).
You will need light weight boots, shorts, light weight trousers (not jeans), t-shirt, sun hat, sun glasses, sun screen, woollie or fleece and waterproofs. Carry plenty of water. For high level mountain walking, make sure you carry additional warm clothing - it may be summer in the valley but at 3,000 + feet it could feel like the middle of winter!
Thermal top, thermal long johns (when its very cold), warm trousers (not jeans), extra jumpers or mid-layer fleece, outer jacket/fleece, waterproof cagoule and over trousers, heavy weight boots and thick socks. Don't forget warm hat, gloves (a spare pair may be useful), headband, scarf. Its a good idea to have a flask with a hot drink, spare water, sandwiches and plenty of goodies - chocolate, cake, to give you an energy boost when you need it. Contact the leader to check if you will need crampons, ice axe or torch.
What you bring will depend on the weather - but you can probably make do without a rucksack if the weather is very settled. But be warned, once the sun starts to set, a very hot day can become quite cool in the hills.... something to put on over shorts and a t-shirt is often a good idea.
We're fairly low tech on the cycling front - not much lycra on show in this group! You'll need a bicycle - and any spares and basic tools you might need and definitely a spare inner tube. Plus usual waterproofs, shorts etc. Although not essential, padded cycling shorts can make the trip much more comfortable. Bring a lot of water - cycling can be thirsty work. (and of course we never ever ever go near a cafe or pub? )
Bedding is provided by the YHA, including cotton inner sleeping bags. You'll need your usual walking gear as above - with spares in case one set of gear gets totally soaked on your first day of walking - plus sleeping attire, toilet bag, towel, and comfortable casual clothes for a hard evening down at the pub. Many hostels provide meals which you will need to book yourself (preferably in advance) with the warden. If you're self-catering, you'll need to bring food with you - pots and pans are provided - its advisable to bring your own sharp knife and can opener with you!
A tent - but if you haven't got one, we may be able to help. Sleeping mat, sleeping bag (a warm one for early or late in the season), cooking gear, fuel, and food, plus your usual weekend clothing. Don't forget to bring a torch, insect repellent and extra (warm) clothing for the evening.
