This scenic spot is located on Lookout Mountain about 30 yards away from the Lookout Mountain Nature Center parking lot. There are a few rocks on the short trail down to this overlook and there aren't many places for guests to easily view. I would recommend ten guests max with five being comfortable. This area is free for use, no permit required.
Swan mountain - Sapphire point overlook, Dillon, CO
Sapphire Point Overlook is a common and exceptionally busy intimate wedding location that definitely requires scheduling and a permit (don't try to do an event there without it). It is located on the South side of the overlook and can accommodate up to 35 guests. The overlook is about 70 yards from the parking lot with a flat easy trail leading the way. There are outhouses on site, but I wouldn't recommend getting dressed in them. The site is a popular hike and it's common for people to hike the trail during the ceremony. Some stop and are respectful while some trudge past. Chipmunks are everywhere here!
This west view over Chatfield Reservoir is about 50 yards west of the Heronry Group Picnic Parking Area. There are restrooms onsite. A permit is probably required, and I would encourage you to reach out to the local agency to get one. However, I have done several intimate weddings here where couples have rolled the dice and there haven't been any issues. As long as the event is small, I don't know that they would actively complain. One of the park rangers even took a moment to wish us well.
This is a new one, but as I was driving past, I couldn't believe the view. Particularly for how close to Denver it was. It was cloudy when I was last there so the photos aren't as glorious as they could be, but this little gem of a spot is really nice. A permit is probably required, and I would recommend that you get one. However, the nearby road isn't heavily trafficked and we generally wouldn't be there for long. This spot is about 50 yards from the parking lot which only holds eight cars. There are no restrooms onsite.
Shadow Mountain - Maxwell falls overlook, Conifer, CO
Maxwell Falls Overlook is a 20 minute hike from the Upper Maxwell Falls Trailhead where there is parking for about 20 cars. There are no restrooms onsite. The hike isn't difficult, but sneakers or hiking boots are required. There are actually three separate rock outcrops to choose from. Each with a slightly different view. I've used this location year round, but a hard snowfall would make the trail impossible to find. The area is free for use. No permit is required.
Swan Mountain - Sapphire POint Overlook (NoRTH), Dillon, CO
Sapphire Point Overlook is a common and exceptionally busy intimate wedding location that definitely requires scheduling and a permit (don't try to do an event there without it). It is located on the South side of the overlook and can accommodate 35 guests. It is the only sanctioned area for weddings in the Dillon Ranger District. However, on the North side of the overlook, about 100 yards from the parking lot, there is a spot with an equally good view yet not as well developed. A couple of picnic tables are here and an event of 8 or fewer people can do a quick intimate wedding without likely drawing much attention. There are outhouses on site, but I wouldn't recommend getting dressed in them.
This charming structure at the Mt. Falcon West Trailhead has quite the scenic overlook. A permit is required. This site can be used for a wedding of up to about 20 people. There is a lot of parking, but it is also a very popular hiking spot and the lot can get full.
Golden gate Canyon - panorama point, Black hawk, CO
Located in Golden Gate Canyon State Park, Panorama Point is set of overlook decks. The main deck can likely seat about 40 people. And there is one small deck about 20 yards from the main deck which can accommodate about 8 people. There are around 20 parking spots and there is a fee for parking within the State Park. Last time I was there, the fee was $8 and payable either at the welcome center or by cash onsite. There are restrooms onsite.
