We are climbing Snowdon soon. Teens are fir enough but not super fit. I am taking this seriously. Ensuring the correct clothing and food and drink etc. We plan to go up via lanberris . Is it really boring to return that way? If we go back down the ranger path is there a bus that can take us back to lanberris? I plan to set off early. To bring a physical map and compass just in case. What else should I be considering? What else should I know?
