This section displays the weather forecast for Llanbedr, which is located to the west and is one of the nearest towns to Y Llethr. Remember that Llanbedr sits at around sea level whereas the summit of Y Llethr reaches 756m. This means that when looking at temperature the adiabatic lapse rate must be taken into account, which in Wales is a drop in temperature of between 0.5 and 1°C per 100m in altitude. Exposure and wind speed can also significantly lower temperatures.
Essential GearY Llethr can be climbed at anytime of the year, however in poor conditions the mountain's rock routes are best avoided, particularly if the weather has been wet. March to April offer the most reliable conditions. Of course this all depends on ones ability as a mountaineer/climber, and what might be comfortable for some may seem daunting to others.
If you’re lucky enough to climb the mountain in winter conditions then an ice axe and crampons would be very useful.
Getting ThereY Llethr is located in the southern portion of the Rhinogydd and can be approached from numerous directions. The best stars however, are all located on the range’s western side, either starting in Cwm Nantcol or Dyffryn Ardydwy
The best starting point is probably from near Cil-Cychwyn (SH 633 258) in Cwm Nantcol, which can easily be reached along narrow roads by leaving the A496, which runs along the coast from Llanulltyd near Dolgellau in the south to Blaenau Ffestiniog in the north, at Llanbedr or Dyffryn Ardydwy.
Alternatively it’s also possible to approach the mountain from the south by parking at Bontddu (SH 672 188) or Cwm Mynach (SH 684 215). The routes from here are less satisfying that the other options though.
The area can also be reached by rail, however getting from the stations to the mountains themselves can be difficult as public transport is pretty infrequent and hitching can be a bit of a nightmare these days.
Red Tape and AccessNo red tape here!
Although unlikely it's worth checking the countryside access map provided by the Countryside Council for Wales (CCW) regarding whether or not any restrictions on movement in the area are in place.
Countryside Access Map
For climbers, hill walkers and mountaineers, the British Mountaineering Council (BMC) runs a Regional Access Database, which holds mountain/crag specific information on matters of conservation and access, including issues such as nesting restrictions, nature designations and preferred parking.
Regional Access Database
If you are in any doubt about any particular access arrangement, or need to report an incident, you should contact your local BMC Access Representative or the BMC Access Officers for Wales: Elfyn Jones.
Camping and AccommodationThere’s an almost unlimited supply of accommodation within the Snowdonia National Park so it would be inappropriate to list it all here. For budget accommodation it’s worth checking out some of the following sites:

Campsites in Gwynedd
For more local options, there are a number of campsites that surround the range. Nearby campsites can be found at Cae Gwyn Farm (SH 713 297) to the east of the range, and Merthyr Farm (SH 600 319) to the west.
For wild camping Llyn Hywl (SH 662 267) and Llyn Bodlyn (SH 648 239) make an excellent locations.
