If you're after "nice" as in attractive as well as a decent fishery and are prepared to travel to the lakes
Ghyll Head and
High Newton
are attractive as is
Bigland, although I don't know how it's fished this year.
Watendlath is very attractive, although I've never fished it and is probably too far.
If small as Kilnsey but well managed, Bank House at Caton, Nr Lancaster is small, well landscaped and also has some big fish in as Kilnsey. It's run by the tenant at Stocks. Well managed, good facilities and clean fish.
If you go there, because it's small, it might be worth phoning up before to make sure it isn't booked up (usually there is loads of room and it's not shoulder to shoulder)
I like Barnsfold, near Preston.
Both Barnsfold and High Newton can get very windy, so if high winds are forecast, I'd give them a miss.
Tight lines, Robbie.
