There are lots of great uphill approaches to greens - this website is littered with references to skyline greens. It's not a skyline green but I love the uphill approach to the 10th green at Royal Troon - I get to play it from the members' tee up on high ground when I think it's a great hole. From the championship tee down in a low, damp corner I think it's ghastly.
At Swinley Forest there some excellent uphill holes - the 7th, for example - with the uphill approach to the double-dog-leg par-4 12th one of the best shots of its kind in England. The 16th at North Hants, 16th on the Blue Course at the Berkshire, 16th at Wentworth West, 13th at St George's Hill, 9th at Liphook, 13th Walton Heath Old, 7th Royal Ashdown Forest, 7th at West Sussex, 12th at Isle of Purbeck, 12th at Burnham and Berrow, 12th Stoke Park, 7th Goring and Streatley, 14th Moor Park High Course, 10th Little Aston, 12th Sherwood Forest, 11th Notts, 7th Luffenham Heath, 6th Hunstanton, 6th Aldeburgh, 18th Thetford, 9th Prestbury, 10th at Sandiway, 5th Cavendish, 1st Delamere Forest, 3rd and 11th Wallasey, 7th Formby, 13th Silloth, 13th Brampton, 9th Slaley Hall Hunting Course, 10th Seaton Carew (Brabazon), 2nd Pannal, 16th Maesdu, 17th Bull Bay, 17th Llanymynech, 4th Welshpool, 13th Southerndown, 9th Royal Porthcawl, are a few in England and Wales that cannot all be great, though some are, but they are uphill holes I really look forward to playing.
