Hi Graham
missing the TT this year but heading over for the Manx
A lot depends on what type of shots you want ( anything you take will be superb anyway
)
Once roads are closed you can be pretty much stuck if you're on the inside of the circuit , Ive not had too many problems crossing under marshall supervision but it is hit n miss .
There's a great spot on the mountain where you can park outside the circuit & cross over which leave you lots of walking to various good viewing spots is....verandah , bungalow,mountain box...food & loo's at the Bungalow.
Sulby is great for long fast shots subject to light as lots of tree's....not sure of the allowed spots but if you turn right at the crossroads (if you're going in the course direction ) you may be able park up there & wander down to view...the road leads you eventually up to the bungalow I belive .
Gooseneck is great for close shots of a semi fast corner & you can get away down the back lane...last time I was there parking was in a field on a steepish slope ! Like wise Braddon bridge good for close ups but slower than you'd think , again you can get away .
Hillberry is ( was when I was there) a cracking spot...park on the outside in the little field ( loo's n food) then you could walk up through a coulle of fields ( not to far) & sit just behind a small wall to watch them come howling down from Brandish , the lovely left sweeper & away up the hill toward signpost corner ...you're literally inch's away from them .
The Glen Helen hotel is another good spot , bit over hung with trees ( less they've cut them down) but again great view's of a couple of bends & away up the hill past Sarah's Cottage & on to the Cronk ....you are stuck there though
Keppel Gate...another goodun , plenty to see as they howl along a semi straight coming from your left , down through a couple of bends then away past Kates Cottage down to the Creg....stuck again though...you may be able to park at the Creg & walk uphill to Keppel .
Governors bridge gives a good view of riders slowing to go through The Nook ( or not slowing in some cases)
Ballugh Bridge....awesome ( well I think so ) park on the outside & cross over ,bag the spot just at the end of the pub wall & keep your spot...think you can park on the lane by the pub but not sure where the road leads . I got there at 7am on race day...just early enough as within 15 mins I was joined by about 20 more people...but breathtaking to watch them over the leap
Parliament Square is ok'ish....if you're in the right spot you should be able to get shots of the bikes squirriling under braking for the sharp right
Last couple of years I've been access to the pit area has been very relaxed...good chance to see bikes n riders up close....they're generally happy to natter
Loads of other place that I've not been to but hope the above helps somewhat
Wherever you decide to go you'll need to get there early & wait....as more places are restricted there's more people for fewer viewing spots.
If you can take a whizz round the circuit when you arrive it'll help you decide where you wanna be...or several whizz's cos belive me....the place is addictive
Getting all giddy about the Manx now
Look forward to seeing your shots mister
