(Lincoln City, Oregon) – Just north of Lincoln City, where the Salmon River weaves its way around three large rocks on its way out to sea, there's a very unique spot for Oregon. Cascade Head and a stretch of land and waterways around it are known as the Cascade Head Biosphere – one of only about 750 biosphere regions as designated by UNESCO. (Photo CHBC)
At the helm of this area is the Cascade Head Biosphere Collaborative (CHBC), which oversees some of its preservation and promotes education on this subject in various ways. Some of those include a lot of serious fun on the Oregon coast.
This summer, the group puts together a variety of gatherings and activities on the central coast, which can take you to some truly secret spots to diving into what's happening in those tidepools at Lincoln City.
On Sunday, June 15, the CHBC presents the Salmon River Estuary Tours. These guided pontoon boat tours provide a chance to experience the estuary up close. Three tour times are available - 4 p.m., 5 p.m., and 6 p.m. - departing from Knight Park (2341 North 3 Rocks Rd, Otis). Tickets are $20 per person.
Guests will board a US Coast Guard-certified pontoon boat for a 45-minute guided journey, led by experienced naturalists. The tour highlights the estuary’s biodiversity, unique geology, and cultural significance, offering insight into its place within the UNESCO Cascade Head Biosphere Region.

"Please note that space is limited, and tours will depart promptly at their scheduled times," the group said. "Unclaimed spots may be offered to standby guests. Due to scheduling constraints, refunds or exchanges cannot be provided for missed tours."
CHBC introduces a new initiative for 2025 - the Biosphere Beach Ambassador program. Scientist and documentarian Josh Havelind will serve as the program’s public representative throughout the summer.
Havelind will be stationed at the tidepools near NW 15th Street beach access in Lincoln City, one hour before and after low tide events. He will answer questions, share insights about the Cascade Head Marine Reserve and Marine Protected Areas, and offer ways to help preserve Oregon’s coastal ecosystems.

Friday, May 23 – 3:50 PM (-0.98’)
Sunday, June 1 – 12:00 PM (-0.45’)
