In case you hadn’t noticed, it’s winter in Jackson Hole. As such, winter season activities are slated to get under way in Grand Teton National park beginning Sunday. Park Spokesperson Jackie Skaggs says as a cost saving measure this year, the Craig Thomas Discovery & Visitor Center will be closed until April 7th. An alternative for winter visitor information about the greater Jackson Hole area is the Jackson Hole and Greater Yellowstone Visitor Center on North Cache Street in Jackson, which is open 9:00 am to 5:00 pm. The Teton Park Road becomes a designated trail in winter and is intermittently groomed for cross-country and skate skiing from the Taggart Lake parking area to Signal Mountain. Dog sleds or snow machines are not allowed on the Teton Park Road and dog sleds are not permitted on Grassy Lake Road on the John D. Rockefeller Jr. Memorial Parkway. Snowmobilers may use the Grassy Lake Road and may be on the frozen surface of Jackson Lake only for the purposes of ice fishing if they have a best available technology machine. Backcountry users and mountaineers planning to stay overnight in the backcountry must get a camping permit before their trip at the front desk of the park’s headquarters building in Moose which is open between 8:30 am and 4:30 pm.
