It appears construction and detours this month are not limited to area roads. Beginning Monday hikers using the southern portion of the popular Jenny Lake trail to Hidden Falls and Cascade Canyon will need to take an upper trail segment beyond Moose Ponds junction. This reroute will be in place for two to four weeks whilesignificant restoration work is done along the more often used shoreline trail. Park officials assure that this reroute does not increase the mileage to Hidden Falls, though. In other trail construction, the Leigh Lake bridge between String Lake and Leigh Lake is currently closed while the park’s trail crew constructs a replacement bridge. The closure will likely last until mid to late June. The bridge provides access to the west shore of String Lake and the junction to Paintbrush Canyon trail.
