Miami - International

1Customs

At the end of NW 25th Street, where the road turns a bit to the south near the customs clearing building, the airport authorities have made special holes in the fence to make photography easier. This holds in particular for making photos of aircraft lining up on runway 12. The same applies to aircraft heading for runway 8R, but heatwaves will trouble you most of the day. Taking pictures of landing aircraft through the holes requires some practice. The best thing about this spot is that photography is officially allowed, according to the signs next to the holes.
Across the road from 'the holes' is a large cargo looking building with dirt parking under a large tree (on 65th Avenue). Park there and not on the paved lot down the road. However, the latest reports are that 'no parking' is enforced here, so beware.

2Cargo building 706

The roof of cargo building 706 offers a great view of the aircraft parked in front of it. Be sure to take the western branch only (thus turn right after driving up the ramp from NW 21st Avenue), as chances are that US Customs will make your life miserable on the eastern branch. However, even here staying here too long will result in a visit of security, so only make a quick visit: read the numbers, make your shot and drive on.

3El Dorado

When runway 9 is used it is possible to make good landing and line-up shots near the El Dorado Furniture warehouse/showroom. This is at the dead end of NW 72nd Ave, off NW 12th St. Do not park at the lot of El Dorado, but only at the extreme end of the road. Still you may be sent away, either by the Miami Dade police or El Dorado staff. The probability of being visited by law enforcement can be reduced by staying away from the fence as much as possible.
In between the road and the runway are some railroad tracks. In case a train passes by, or is "parked" there, your view may (temporarily) be obstructed. In that case you can back walk about 50 metres to a parking area near Armondo's Check Casing.
Runway 9 is used in particular by cargo aircraft, both during arrival and departure. So when you stay only at the Customs (spot 1), you may miss them completely.

494th Aero Squadron restaurant

The only 'legal' place left along the Perimeter Road on the south side of the airport is at the parking lot of the 94th Aero Squadron which is accessible from northbound NW 57 Avenue, just north of the 836 overpass. It is good for "loggers", but less suitable for photographers, because between the car park and the fence is a busy road and a railroad and you are not allowed to use stairs within 10 feet from the fence. Effectively this means that you need to stay on the south side of the road. Still with a long lense you may still be able to take some pictures.
Just south of spot 4, on Blue Lagoon Drive, the Hilton hotel offers great views over the airport.

5Maceo Park

If you are only interested in taking landings photos of aircraft landing on runway 30, there are two spots alternative to the restaurant (spot 4). The first one is in the northeast corner of the Maceo Park, off NW 7th Street. You can park your car west of the entrance and then need to walk through the park. The aircraft will be visible for about 15 seconds and you will hardly hear them until they are close to you, so keep your camera ready!

6Blue Lagoon

The dead end of NW 47th Avenue is itself an alternative to spot 5. You are closer here, but also a bit more underneath the approach pad. It is just a matter of what you like most. It is advisable to be with someone here, to avoid looking too suspicious.

7George T. Baker technical school

With westerly winds runways 26L and 30 are the main landing runways. For the first runway you need to be near the George T. Baker technical school, for example in front of the Avis Rent-A-Car centre. From this spot you have a short time to get the inbounds as they come over a group of trees and pass before you. Not the best place, but doable when they are using 26L.

8Comfort Inn

High level rooms in the odd range ending between 03-15 give you excellent views on runway 08L/26R and 08R/26L arrivals and departures. Also aircraft at the north side of the terminal can be identified easily. Action on the other runways can also be seen from here, but reading off is difficult is impossible due to distance (heatwaves). Having an SBS set up in your room may do the trick for these aircraft.
Taking photos is difficult, as there are double windows. You may be able to open one window with some tool, but still need to deal with the other window.
