Last Chance to Experience Crater Lake Before Trail Closures in 2026
If you have dreamed of swimming or boating in the stunningly clear waters of America’s deepest lake, now is the time to visit Crater Lake National Park. The park’s only access point to the lakeshore will close for construction starting in 2026, making this summer your last opportunity for a while to enjoy these activities.
Closure Schedule for Cleetwood Cove Trail
The National Park Service has announced that the Cleetwood Cove Trail and Marina will undergo significant upgrades to enhance safety standards. The closure will commence in 2026 and is expected to last through 2028.
- Closure Period: 2026 to 2028
- Activities Affected: The trail will be closed, which means no boating or swimming in the lake during this time.
- Reopening: If everything proceeds as scheduled, the trail will reopen to the public in the summer of 2029.
During the construction, visitors will only have the option to view the lake from above, as all access to the water will be restricted.
Insights on Crater Lake
Crater Lake, located in south-central Oregon, is not just breathtaking; it is also the deepest lake in the United States and renowned for its exceptional clarity. According to the National Park Service, this unique body of water was formed within a volcanic caldera resulting from the collapse of Mount Mazama, which occurred approximately 7,700 years ago.
