The trailhead is across the parkway from a pullout on the south side, between mile markers 14 and 15. The path rises about 0.4 mile each way, so expect a steady climb rather than a level stroll. A parking tag is required if your vehicle is parked longer than 15 minutes, and no reservation is required. Pets are not allowed on the tower trail.
There is no restroom at the tower pullout. The nearby Look Rock Picnic Area has picnic tables, grills, and seasonal restrooms, typically from late April through late October. There is no food service at the tower itself.
