I have mapped several hundred trails in and around our local mountains. They are all described on a website; www.mountain-meanders.com.
On the trail description, a link is added on the trail head parking on Google Maps. Is there any way to add a reverse link so that having got to the trail head parking, users could be shown the walking routes a available.
None of the links or routes are proprietary. They are all free and in the public domain.
