If you're coming to St. John's at all, I suspect Signal Hill is already on your to-do list. If it's not? Well, then I worry that you just have no idea what you're doing because Signal Hill is Newfoundland at its finest. Well, the best you'll get within five minutes of downtown St. John's, that is.
The winding Signal Hill Road takes you past Deadman's and George's Ponds up one side of the incredible narrows of the city. On top, you'll find Cabot Tower and the most spectacular views the city has to offer. In one direction, the vast Atlantic ocean with a chance of Cape Spear (the furthest eastern point in North America) on a clear day. In the other, the city itself - a view that is electrifying by night.
Of course, you can also pop into Cabot Tower which is open to the public with a shop on the lower level, more historic elements on the higher ones, and a wind tunnel-y observation deck on the top floor that'll knock your socks off. Perhaps literally. Other attractions include the changing of the guard which I've admittedly never witnessed. This happens a little lower down on the hill next to the visitor's centre.
If you are of able body and somewhat unsound mind, you can tackle the Signal Hill hike that's equal parts beauty and beast. I'd rank it pretty high up there on the fitness scale with hundreds of wooden steps, the occasional rock jump, and a surprisingly low amount of 'stupid tourist safety measures.' In fact, for most of the hike just one slip would have you in the ocean so watch where you walk. Just remember to take breaks occasionally to take in the cliff-side views, would you?
The walk, while wonderful, does take anywhere from an hour to an hour-and-a-half. Having done it both ways, I'd recommend starting at the bottom off Battery Road and hiking up along the water, then enjoying the downward climb of Signal Hill on the way back.
