Trail systems
Bertram Chain of Lakes
Official Wright County trail map (2019) names 15 distinct singletrack segments totaling 14.25 miles. IMPORTANT: the official map does not publish difficulty ratings for any segment or for the system as a whole. A prior version of this record incorrectly stated the system was "IMBA green-rated," based on Trailforks commentary rather than the official source -- that claim has been removed. Trailforks (non-official, supporting-tier) does rate most segments green-to-blue on its own site if a difficulty estimate is needed for UI purposes, but that should be sourced/labeled as Trailforks own rating, not the county's.
