YHA Minehead
Just in the process of booking this for a weekend in May for the club (about 30 people). Haven’t been for a couple of years but used twice in the past.
Excellent access out the back of the garden straight onto Exmoor (just don’t ride all over the lawn!). Good food (they will do breakfast, dinner and IIRC packed lunch too), plenty of showers, secure bike storage and some bike washing facility, large drying room.
Recommended.
The Campbell Room noted above is Quantocks, not Exmoor – however its a great place to stay on a budget (works out at £10 pppn if there’s 12 of you). Its a scout hut with a kitchen, 2 showers and a small cabin. Sleeping is on plastic mattresses on the floor, pretty basic but fine for a lads weekend MTB’ing.
500 yds from the bottom of the hill, and not far from the bottom of Bin Combe which is the best way to end any day biking!
