4km easy access in so taking an old bike in is a good idea. Straightforward hike. Grassy slope launches best southwest aspect but south and west launch options also good. Avoid higher wind days due to proximity of other hills and possible leeside turbulence.
Access and parking
Fairly remote, unlikely any issues, no restricted airspace issues but can check NOTAMs just in case.
Forecasts are planning aids, not safety clearance. Check current observations, official airspace and NOTAM information, local rules and your own experience before every flight.
