The Tremymor people have stopped running retreats now.

We've got a book with lots of retreats listed in it. When I have a bit more time I'll post its title.

Rennaldburn is a seventeenth-century farmhouse, reputedly the first house built by Thomas Telford under the apprenticeship of a master stonemason.
It sits secluded in three and a half acres of land, part of which is a wooded ravine with a beautiful waterfall running through it (and two-storey tree house overlooking it!), two miles South of Samye Ling Tibetan Centre in Eskdalemuir (in-between Lockerbie and Langholm in Dumfries and Galloway).
Visible from the house and five minutes walk away, by the river Esk that winds through the valley, are the Loupin Stanes. This is one of many prehistoric sites in the area, including the Girdle Stanes, another ancient stone circle twenty minutes walk down the valley
The centrally heated farmhouse has recently been lovingly refurbished in an earth-friendly way, and has many unique features inside. Upstairs, there are two double bedrooms looking out on the valley as well as a small single room with a skylight. Downstairs is the sitting room, also with an open fire. This holds an extensive library, specialising in books of a spiritual and esoteric nature (particularly Tibetan Buddhism). There is also a music system, computer (with broadband, DVD player and selection of DVDs) and pedal organ. The under-floor heated kitchen, with all cooking and washing facilities, has a door leading to the front garden.
Rennaldburn is vegetarian, non-smoking, and child-friendly, with cot and high chair available if required.
