At just over 2,500 feet, it's the highest point on the TMT. In spring, look for red currant blooming here. From Tom's Crossing, the West Tiger #2 Trail heads steeply uphill providing another way to reach that summit. Continue down the TMT on many switchbacks and, in about 0.3 mile, note the junction with the K3 Trail.
I rarely show up more than 1.5 ahead of time. Another idea: technically, the ticket counters usually open 24 hrs before your flight, and sometimes this is the only way to easily get special seats like exit rows.
Best Answer: I would show up at least 3 hours before the flight. You want to give yourself enough time to go through security and get to your gate. Just know that you don't want to show up to late to the gate as the gate can close 20 minutes prior to departure.
