Taking the route via Jacobs Ladder was well worth it. It only cost £5.50pp however is valid for a whole year. Although there are free walking routes, Jacobs Ladder is the quickest and easiest to get to the first initial ascent.
The views from the top are breathtaking. It may be an idea to carry a walking/hiking stick to take pressure off knees/legs. The journey for novice climbers will take approx 1h 40 - 2 hours.You may feel like giving up, but honestly, you'll be glad you pushed yourself through it. Just make sure to take in the sites from the top and view of the lake. ;)
