Borrow a jobsworth jacket, hard hat and lanyard and see how far you can penetrate into the BAE submarine base before being stopped? Better take some real ID like a pssport to prove your real identity.
I’d definitely climb Black Combe because it’s such a prominent hill, you can see it from almost anywhere on the Fylde coast or any high spot in Lancashire. Wiki says:
The view from Black Combe is unique, a result of its isolated position to the south and west of the main Lake District fells. William Wordsworth claimed that “the amplest range of unobstructed prospect may be seen that British ground commands.” Half the view is the glittering sea, with the Isle of Man seen clearly to the west, and the hills of Wales and Scotland seen as shadowy silhouettes.
On the seaward side views extend from the Cumbrian coast, and from Criffel, 49 miles to the north, a mountain on the Scottish coast near Dumfries, round to the Isle of Man, 45 miles due west, then round to Snowdon which may be seen on days of exceptionally good visibility, 85 miles to the south, to the coast of Lancashire. On the landward side; views include the Scafell Group and the Coniston Group of fells in the Lake District National Park, including four 3000-foot mountains: Skiddaw, Scafell, Scafell Pike and Helvellyn. To the east and south the Pennine Hills, the Forest of Bowland and Blackpool Tower are visible. Closer by, there are also good views over the Duddon Estuary, Millom and the new wind farm just offshore.
