GPS tracks and geolocated maps are provided as a guide only and do not replace paper maps. GPS tracks can be inaccurate for various reasons and the tracks provided here do not necessarily accurately represent any tracks or imply any right of way. Track position may change over time. Always stick to the marked tracks if possible and obtain recent local information before hiking.

Best efforts are made to provide accurate information about licences, etc. but rules change over time. Locations indicated do not imply right to park or access the rivers at the given locations. Always obtain recent local information before fishing.
