I went to the Marin Trail a couple of weeks ago, for the first time in about 10 years, at the end of a weekend riding at CYB and clambering on the Snowdon Massif.
The Marin Trail was ok. The new bit was excellent, but much of the rest was fire road and/or quite forgettable. Some of the southern part was quite pleasant.
-As one of my friends pointed out, it illustrated just how far things have improved at other trail centres.
Interestingly, as somebody who often has a good recollection of these things, I had hardly any memory of the Marin Trail at all, other than the (good) Dragon’s tail(?) and the (fairly good) final descent, from the previous 2-3 times I’d been there.
I wouldn’t make a special effort to drive to the Marin Trail, but would to Penmachno and CYB.
