In reply to eivhje: The ben from Fbill is not too much longer than from the NF especially if youve got a nice hotel to walk back too. The norries are another option; bus from aviemore or hitching a lift is quite easy. Again glencoe you can easily get a lift up to the climbing areas. Im sure there are plenty of other areas but these three are easy to get to on public transport (relatively) and have accommodation, steady traffic and are reliable.
